Medium Voltage Cable: The Complete FAQ Guide

What is Medium Voltage Cable?

A medium voltage cable is a category of cables that carry voltage of between 1kV to 100kV.

Medium voltage cable

 Medium voltage cable

How does Medium Voltage Cable compare to High Voltage Cable?

Medium voltage cable transmits medium voltage of between 1kV to 100kV and voltage range of between 240V and 360V.

High Voltage Cables transmits voltage high voltage of above 100kV and a voltage range of above 600V.

High voltage cable

 High voltage cable

What is the Best Material for Medium Voltage Cable?

The best material for medium voltage cable includes:

· Aluminum

The advantage of aluminum is that it has a non-ferrous property as well as it being highly conductive.

However, it is a poor soldiering material on its own.

Also, it has poor oxidation, and it is highly corrosive

· Copper

It is an ideal material due to its attenuating and magnetic waves properties.

As such, they are of common use in hospital and laboratory electrical equipment.

You can easily fabricate this material with other materials such as alloys of bronze and brass.

However, this material is relatively expensive when you compare to aluminum.

Medium Voltage Cable uses which insulation material?

The type of insulation material used for medium voltage cable includes:

· Cross-linked Polyethene (XLPE)

XLPE consists of different linked polyethene.

This prevents the melting of the polymer as an insulation material.

XLPE is ideal for use in high-temperature marine applications.

· Ethylene Propylene (EPR)

EPR offers a flexible insulation material than XLPE and PE.

Its operating temperature is between 90C and 100C.

However, it has a high dielectric loss than most insulation materials.

What is the Importance Shielding Medium Voltage Cable?

The importance of shielding medium voltage cables include:

  • To reduce electromagnetic interference, which affects the quality of signal transmission.
  • To reduce electromagnetic radiation
  • To minimize crosstalk between cables that are close to each other.

How do you Slice Medium Voltage Cable?

You will use a lineman’s pliers, wire stripping tool inner cutter or diagonals to slice a medium voltage cable.

How do you Conduct Resistance Test for Medium Voltage Cable?

You will need a multimeter if you want to conduct the resistance test for a medium voltage cable.

The resistance test is affected by the thickness and length of your medium voltage cable.

An increase in the length or thickness of your medium voltage cable increases its resistance.

You need to set the multimeter to ohms before using it.

Ensure that it reads zero.

Place your cable on a wooden surface or a towel.

Place the ends of the multimeter on the end of the medium voltage cable.

The acceptable range of a proper function medium voltage cable should be at most 2 ohms.

What are Medium Voltage Cable Quality Standards?

Medium voltage cable

Medium voltage cable

The quality standards for medium voltage wires include:

  • IEC 60092 standards. they explain the standards for installation of these cables for voltages of up to 15kV
  • JIS C 3410 standards is a Japanese standards requirement which has its international standard equivalents.
  • DIN 89158?159/160 standards explain the quality aspects of the ship’s electrical cables.
  • BS 6883 & BS 7917 describes the quality specifications for fixed wiring of the ship electrical cables. It also offers the testing methods for these cables.
  • VG 95218 standards specify the quality of cables that you can use for fixed installation.
  • UL 1309 standards explain the requirements for distribution, signal and control cables
  • IEE 1580 standards specify the quality of ship electrical cables for use in harsh environments.

There are other quality standards whose use depends on the country of use of the medium voltage cables.

Is there Voltage Range for Medium Voltage Cable?

Yes. There is a voltage range for medium voltage cables. This is between 2,000V and 35,000V.

Should you Choose EPR or XLPE Insulation for Medium Voltage Cable?

EPR has numerous advantages over XLPE when used as an insulation material for medium voltage cables. They include:

EPR has high flexibility properties

EPR has a lower thermal expansion, which makes it ideal for use in high-temperature applications.

It has high abrasion properties.

It has a high resistance to water treeing.

What are the Characteristics of Medium Voltage Cable?

The characteristic of medium voltage cable includes:

  • Fire-retardant minimizes the occurrence of fire outbreaks within the cables.
  • High electrical conductivity facilitates the transmission of electricity.
  • Low smoke ensures there is low smoke in case of a fire outbreak. This helps in containing the fire.
  • Abrasion resistance reduces exposure of the cables as a result of wear and tear.
  • Halogen-free ensures there are no halogen elements such as chlorine
  • High-temperature resistance helps in ensuring the operation of these cables in high-temperature applications.

Medium Voltage Cables have how many Cores?

Medium voltage cables can have different cores depending on the area of application.

That is, you can have 2-core, 3-core or 4-core medium voltage cables.

What is the Recommended Color Coding for Medium Voltage Cable?

The recommended color coding for medium voltage cable is: red, yellow with green, black and grey.

When Should you use Medium Voltage Cables?

Among the reasons that you should use medium voltage cables include:

  • They are extremely durable and flexible.
  • They are easy to install
  • They have a reinforced jacket that increases their resistance to pulling, tension and twisting.
  • They have a high resistivity to moisture and high heat and oil.
  • The copper used offers a high electrical conductivity
  • Their manufacturing takes into consideration the extreme abuse application.

Is there Specific Color Coding for Medium Voltage Cable?

There is no specific color coding for medium voltage cables.

The color coding for medium voltage cable depends on the internationally recognized standards.
