The alarms rely heavily on signal transmissions.

The telephone cables thus are significant in relaying the signals for initiating the alarm sound.

That’s not all, the uses of the telephone cables are diverse and numerous in the shipboard; actually, they’re the determinants of effective communication in the whole shipboard setting.

Along with the uses, you need to be conversant with the different structures of the cables.

Read along to get a complete assessment of the specific parts.

Structure of Marine Telephone Cables

Unlike ordinary telephone cables or other offshore cables, marine telephone cables are distinct and unique in their design.

That’s evident from its cross-sectional area of the cables.

You’ll notice specific cross-sectional parts and regions.

All these segments serve a particular role in complimenting the overall information transmission.

The following are the structural parts of the cable: from the outer covering to the most interior layer.

Types of Marine Telecommunication Cables

The telecommunication cables exist in various kinds.

We shall discuss the most common ones:

Marine Telephone Cable Quality Standards

Remember how harsh and adverse conditions can be in the marine environment.

You, therefore, wouldn’t want to waste your money on products that aren’t worth it.

That’s why, when it comes to marine telephone cables, you have to watch out for the various certifications and approvals from the relevant institutions.

In this segment, we shall discuss a few but vital quality standards that the cable constructions must comply with to make safe for use in the marine:

They include:

  • IEC 60092-3 Standard
  • JIS C3410 Standards
  • DIN 89158/159/160 Standards
  • BS6883 & BS7917 Standards

Note that these are just a couple of the standards though there’re myriads of them that we can’t handle in this little segment.

· IEC 60092-3 Standard

IEC60092-3 is an international standard for ship wiring that takes care of power cables and instrumentation cables both for the ships and mobile/ fixed offshore units.

The following are the seven critical sections of the IEC 60092 that touches on electrical installations.

IEC 60092-350: 2001, Deals with the electrical installations in ships covering the shipboard power, instrumentation and control cables that have got copper conductors.

Such wires must have a maximum voltage of 36KV.

Specifically, it provides an outline of the constructional requirements and test procedures for those cables.

IEC 60092-351, This version covers the guidelines for the design of the insulation materials for the power, control, instrumentation, telecommunication and data wires.

IEC 60092-352: Guidelines for the selection and installation of wires for the fixed systems ( non-flexing ) on board ships which have got voltage ratings of a maximum of 15KV.

IEC 60092-353: 1995: Deals with both single and multi-conductor non-radial power cables embedded with extruded solid insulation but with voltage ratings of 1kv up to 3kv.

These also for non-flex installations.

IEC 60092-354: Single and triple-core power cables embedded with extruded solid insulation, conductor, and core screening for voltage ratings of 6KV up to 30KV for non-flex installations.

IEC 60092-360: Sheathing materials for the power, instrumentation, control and telecommunication cables.

IEC 60092-376: screened and non-screened wires for control and instrumentation circuits with solid insulation and voltage rating of 150/250 V.

· JIS C3410 Standards

This standard provides recommendation for the approval of the cables and the flexible cords for all the electrical equipment in ships including telephone and switchboard installations.

It also covers the insulated wires.

However, these tests come after completion and compliance of the previous IEC 60092-3.

A typical example of the above tests is 0.6/1 KV FR-FA-TPYCY cable.

· DIN 89158/159/160 Standards

For this certification, the DIN 89158 deals with the scope for electrical cables for both the ships and offshore units, especially the armoured/ shielded power cables.

The type DIN 89159 applies to electrical and telecommunication cables which are halogen-free.

Lastly, DIN 89160 covers the ship electrical cables without armor.

· BS6883 & BS7917 Standards

The British Standard BS7919 also provides a scheme for covering cable types for fixed installations on ships and offshore vessels.

However, it supplements the BS6883 which includes the marine cables especially those used for the fixed wiring of the lighting, control, power, instrumentation and propulsion circuits of voltage rating up to 3.3Kv that have no fire resistant integrity.

It thus outlines the manufacturing requirements and necessary fire-related tests.

Indeed the BS7917 Standard champions the implementation of cables resistant to fire.

That’s why it recommends the use of tapes on top of the conductor or insulation to make it fire resistant.

According to the BS6883, all the cables designed about the BS7917 are labeled depending on the type of outer sheath they have.

Such as;

BS6883 Type SW2 cables are flame retardant, heavy-duty oil resistant and minimum halogen gas emit.

BS6883 Type SW3 cables: these are ordinary oil resistant, low smoke and corrosive gases emitters under fire conditions.

BS6883 Type SW4 cables: ordinary oil resistance, little smoke and gas emitters under fire conditions.

Additionally, the BS7917 outlines the fire resistance performance as below;

  • FO Cables- fire resistant for approximately 3h at 750 °C.
  • F1 Cables- fire resistant for approximately 3h at 950 °C.

Now that you already know the types and the certification standards for the cables, I bet you should consider the properties of these cables. That’s next.

Features of Marine Telecommunication Cable

Now during our course of study, you must have noticed that marine telecommunication cables are entirely different from the ordinary telecommunication cable or any other cable.

This because of their outstanding features to deal with the maritime environment.

Now, let’s look at these distinct features.

Figure 9 Different types of marine telephone cables

· Number of Marine Telephone Cable Core

The number of cores varies.

Accordingly, they could be single, double or multiple such that the core numbers are either in pairs or triples of 1, 2, 3, 4, 5,7, 8,10,12,14,16,19,24,27,30,33,37

· Flame Retardant

For surety of flame retardancy, the marine telephone cables pass the standard tests according to IEC 60332-3-22 A which is a full guarantee of safety on board of marine ships, and other offshore units in the event of a fire.

Additionally, through these tests, the cables don’t propagate fire.

Besides, the flame, the cables also produces little smoke during a fire outbreak on the ships, ensuring safe conditions onboard.

For such reason, it passes the IEC 61034 test.

As we earlier mentioned, the marine environment comprises of halogens such as chlorine, bromine, iodine, fluorine, and astatine.

They are highly reactive, producing dangerous gases, which in turn pollutes the surrounding air.

Besides, that kind of reaction reduces the durability of the cables.

For that matter, the telecommunication cables are halogen-free.

For confirmation, these cables pass the IEC 60754-1 test standard.

Moreover, some telecommunication cables use ethylene propylene rubber or the cross-linked polyethene tape and insulation.

For the sheath, SHF1 or SHF2 is advisable, but all must be halogen-free.

What’s more, these cables are fire resistant, meaning they cant quickly burn and discourages the spread of fire.

Fire resistance feature is evident from the IEC 60331-21test standard.

· Colour Code

The color codes are vital in the identification of the cores and sheath of the different types of cables.

For a pair of cores, the colors are white and blue, triple cores have got white, blue, and red colors, while for the quads, it’s black, blue, red and white.s

On the other hand, the sheath colors are blue, black, gray and even green.

· Cross Section Area

The nominal cable cross-sectional areas are 0.75sqmm, 1sqmm, 1.5sqmm, 2.5sqmm.

· Conductor Type

The common conductor types in use are of two types, ie.

Class 2 and class 5.

Class 2 conductors are stranded bare copper conductors while class 5 comprises of tinned annealed copper conductor.

· Insulation Material

For the insulation, you have a range of options to select from.

Thermoplastics are specifically, PVC, PE, or thermosetting type of materials such as EPR and XLPE, TR-XLPE.

However, for the cables with multiple numbers of conductors, sometimes thin layers of silk and cotton are enough.

· Working Temperature

Different types of marine telephone cables have a varied range of operating temperatures.

The minimum temperature among them being -25 °C while the maximum is approximately 95 °C.

· Nominal Voltage

The shipboard telecommunication cables typically have nominal voltages of 150/250 V.

· Bending Radius

The minimum internal bending radius is commonly 8 x OD (Overall Diameter).

· Outer Diameter

The outer diameters vary by the number of cores present in the cables by cross section area. i.e. ( No. of cores x cross section area). Such that:

Multi-Pair – Min. OD is 11.9 mm, and Max. OD is 55.5 mm.

Multitriple – Min. OD is 11.9 mm, and Max. OD is 37.3 mm.

Multiquad – Min. OD is 12.8 mm, and Max. OD is 34.0 mm.

Remember, these dimensions vary.

· Weight

Similar to diameter, the masses also vary depending on the type of wire, several cores, size of conductors and the overall diameters.

Please contact your manufacturer for accurate weights depending on those parameters.

· Individual Screen and Overall Screen

A single select screen exists over every insulated conductor.

The screen shields the conductor against noise, radiations or any other interference.

These screens may be metallic, i.e. (copper or aluminum) or semi-metallic (PETP/AL) tape.

Aside, an overall screen attaches over all the insulated conductor bundles for similar functions.

· Drain Wire

A drain wire connects every single screen, thus helping in the termination of that screen.

· Armour

The armor protects the conductor against mechanical damages.

Steel wire armor (SWA) recommended for multi-core cables while Aluminium wire armor (AWA) for single core cables.

So those are the features associated with the marine telecommunication cables.

The next segment is critical, as well.

How to Handle Marine Telephone Cables

Even though we earlier on showered these cables with a lot of praises concerning their suitability on usage in a harsh environment, you still have the mandate to handle them appropriately.

From packaging to installation, you shall get the complete guide on what to do.

Figure 10 Marine cable handling

·  Packaging Marine Telephone Cable for Shipping

Packing of cables is quite easy and straightforward to do.

All you need to have is a wooden drum. After that, intertwine the full length of the wire over the wooden drum in a circular manner.

That’s all.

·  Handling Marine Telephone Cable during Installation

Consider the following measures:

Minimum Bending Radius

For a marine telephone cable, the least bending radius should be 8 x Overall Diameter (OD).

Caution, Don’t make the internal bending radius during installation be lower than that dimension.

Sidewall pressure.

Here we’re referring to the side wall pressure to the cable ie.

Tension ( Kgf) / Bending radius(m) = T/R = 500 kgf/m.

Maximum Permissible Pulling Tension (T)

Tension = 7 x ( No. of cores) x ( cross-section area of a copper conductor)

Handling Cable Drum

Carefully handle the drum.

If the drum is so heavy, then use a forklift or a crane to offload it from the vehicle.

Always, station the drum uprightly on its flanges.

Undoubtedly, handling and installing the cable is pretty simple.

Marine Telephone Cable Certification

Significantly, a quality marine telephone cable has lots of trade certificates issued by several societies globally.

The several marine telecommunication cable certifications are solely to show the degree in which the cable conforms to set standards.

Most of these organizations are active members of the IACS ( International Association of Classifications Societies).

Take a look at the certifications.

· ABS

The American Bureau of Shipping certification covers the manufacturer ability and the cable design material.

Therefore, two basic assessment checks are necessary, ie.

Manufacturing assessment (MA) and Product Design Assessment (PDM).

MA incorporates various inspections regarding the suitability and compliance to the manufacturing standards as set out by the ABS.

PDM, however, verifies the usage of quality material for manufacturing the cable.

· BV

Bureau Veritas certification issued only after the compliance of the technical quality standards of the cable.

Some of the certificates under this category include conformity assessment certification, product design assessment, type approval, and individual product manufacturing testing.

· LR

Lloyd’s Register Group Limited (LR) issues several certifications mostly for tinned marine cables after guaranteeing that the marine cables obey their industrial set practices.

These include manufacture, tests, materials etc.

LR certification shows the compliance of UK marine standard practices.

· DNV-GL

DNV-GL certification aims at verifying the quality standards of a cable.

The verification process entails QA and QC, technical design, manufacturing witnessing, joint witnessing etc.

· NK

Nippon Kaiji Kyokai is certificate is not only for compliance with Asian maritime set standards and practices but also globally.

The NK standards peg its validation on the suitability of the cable materials and use of non-pollutants in the marine environment.

· KR

Korean Register of Shipping tests and evaluates the marine telephone cables by the societal standards and regulations.

They also offer other maritime related quality services.

·  RINA

Registro Italiano Navale performs quality assessment tests and other services covering various ship equipment such as marine cables.

The certification includes; type-approval certificates.

· RS

Russian Maritime Register of shipping approves the ship cables and shipbuilding accessories.

As such, it tests the suitability of marine cables in assuring the safety of use and onboard life ships together with preventing maritime pollution.

When contracted, they also offer third-party certification and technical services for the shipbuilding and material inspections.

Conclusion

Now throughout this guide, you realize that marine telephone cables aren’t complicated to understand which therefore translates into purchasing.

But before proceeding with making a quotation, always remember that quality has to be your top priority.

Failure to select a standard cable possess a great danger to the entire maritime industry not only in terms of safety but also about pollution.

Always remember that.

Luckily you now have all that it takes to buy such high-quality cable.
