H05RR-F Cable

H05RR-F Cable
  • Feature: Flexible, Cold resistant, Ozone resistant
  • Rating Voltage: 300/500V
  • Structure: CU/RUBBER/RUBBER

H05RR-F cable is flexible rubber sheath cable used as fixed installation. It can provide power to portable appliances in homes and commercial places. Since these are essentially rubber cables, they are very good for coiling.

The H05RR-F is the harmonized code for such cables and is used as their name. You may also see these cables as 318-TRS. These cables come in multiple cores: 2 cores, 3 cores, 4 cores, and even 5 cores.

These aren’t heavy-duty power cables, so these aren’t ideal for industrial or heavy commercial use, as they cannot support the voltage and current requirements for such applications.

H05RR-F Cable Buying Guide

H05RR-F cables are some of the most common cables in residential and commercial use.

These are lightweight cables that help power a plethora of devices.

So you’ll see them everywhere.

Before you buy these cables, it’s imperative to understand their construction, features, and benefits.

This post covers all of those, so you can invest in reliable cables.

Even if it’s not an industrial use cable, it does warrant some attention to ensure all the compliance standards are met.

What is H05RR-F Cable?

H05RR-F are flexible rubber sheath cables used as fixed installations.

These cables provide power to portable appliances in homes and commercial places.

Since these are essentially rubber cables, they are very good for coiling.

The H05RR-F is the harmonized code for such cables and is used as their name.

You may also see these cables as 318-TRS.

These cables come in multiple cores: 2 cores, 3 cores, 4 cores, and even 5 cores.

These aren’t heavy-duty power cables, so these aren’t ideal for industrial or heavy commercial use, as they cannot support the voltage and current requirements for such applications.

H05RR-F Applications

H05RR-F cables are typically used for powering portable and home appliances such as coffee makers, blenders, hairdryers, vacuum cleaners, etc.

These cables can be used in damp conditions outdoors, but only temporarily. So you may also see them with portable devices for outdoors.

These are also used for lightweight workshop tools such as a small drill or electric saw.

Difference between H05RR-F & H05VV-F Cable

The difference between H05RR-F cables and H05VV-F cables is of construction as the material of the insulation and sheath differs.

While H05RR-F cables use rubber, the H05VV-F cables use PVC insulation and sheath.

While both rubber and PVC are great materials for insulation, they have a few differences.

First of all, PVC is cheaper than rubber, which is basically a combination of PVC and silicone.

Rubber offers more flexibility and abrasion resistance, whereas PVC offers more chemical resistance.

The applications and voltage ratings are similar for both these cables, as they use the same type and form of conductor.

Both of these cables help power small portable household and office devices.

Rubber cables like H05RR-F work better outdoors as compared with PVC cables. On the other hand, PVC cables offer higher operating temperature ranges.

So it really just comes down to the conditions around the application when choosing between these two types of lightweight cables.

Construction

The construction of H05RR-F is pretty straightforward:

Conductor

The conductor of these cables is a flexible stranded copper, typically class 5 copper.

The quality of the conductor is indicated by the standards followed by the manufacturer.

Insulation and Outer Sheath

Rubber is the main material in H05RR-F cables.

The insulation is a rubber compound, and the outer sheath is entirely rubber.

Rubber insulation and sheath are inherently water-resistant.

They can also bend pretty well as rubber is a highly elastic material.

Lastly, it also acts as a flame retardant.

As for mechanical stress, these cables have a lightweight construction and don’t have metallic armor, so they can only withstand light mechanical pressure.

Cores

The number of cores varies by specific cable construction, and it depends on your application.

Two core cables are the most common, as most handheld devices and tools use dual-core cables.

Colors of the cores depend on whether the manufacture follows a color-coding standard, such as HD 308.

Characteristics

Here are the characteristics/features of H05RR-F cables:

Voltage Rating

The voltage rating of these cables is 300/500 V, which is more than enough to power small appliances.

Operating Temperature

The operating temperature may slightly vary by manufacturer, but typically -25 to 60 degrees.

There are other such cables with different harmonized standards that offer even higher temperature ranges.

As you can tell, these cables are not fire-resistant, as they are not high-temperature cables.

Bending Radius

Rubber is extremely flexible, which is why these cables have a high bending radius.

It can be four to eight times the outer diameter of the cable.

This is why it’s very easy to coil these (you may see them as recoil cables in some small appliances).

Fire Retardant

While not flame-resistant, rubber is a fire-retardant, so it does provide some form of fire safety.

It won’t propagate fire, but it will not be able to withstand very high temperatures.

Standards

Almost all cable manufacturers use international standards for producing cables.

These standards, commonly IEC and BS, dictate the materials, properties, and applications of the cables.

In the case of H05RR-F cables, each component is used following international standards.

For instance, the class 5 copper conductor is per IEC 60228 standard.

In the British Standards system, the standard numbers for these cables are BS EN 50565-2 and BS50525-1-21.

The current rating is according to IEC 60364-5-52 standard.

There may be regional standard ratings as well for such cables in local markets.

Also, you should look out for certifications such as ROHS and CE, which confirm that these cables use non-hazardous materials.

Advantages

Here are some of the advantages of using these rubber cables with small appliances and tools:

  • Flexibility: These are highly flexible cables that can be coiled and turned. Handheld devices require such bendable cables so as to ensure the power supply is consistent even when the cable is coiled.
  • Fire Retardant: These rubber cables are fire-retardant, so they don’t result in more damage in case of a fire.
  • Halogen-free: Halogen can be dangerous in cables because when oxidized, they can produce harmful gases. Rubber doesn’t contain any of the halogens.
  • Abrasion Resistant: These cables offer adequate abrasion-resistant, enough to withstand light mechanical pressure. This is why these cables last long in domestic use.

Conclusion

H05RR-F cables are essentially for domestic use and certain commercial activities like small workshops or offices. These help power light handheld appliances that don’t have a higher wattage.

These cables are not for agricultural or industrial use as the max voltage is 500 V.

It’s imperative to choose cables that are manufactured following strict international quality standards.

So make sure to check which standards the particular cable you choose follows.
