The 11kV XLPE cable is one of the greatest and best selection in high power distribution in commercial places or areas.
11kV XLPE power cables have a very simple structure. These cables can be used efficiently and are convenient. Also, 11kV power cables can be implemented or installed without the limitation of various levels.
The long-lasting operational temperature of 11kV XLPE cables is 900 ℃. Also, these cables have a very high transmission capacitance. They are available in different colors and sizes as well.
These 11kV XLPE cables exist in two cores; single-core 11kV XLPE cable and three core XLPE cable. 11kV XLPE cables are basically insulated with XLPE with PVC armor.
This cable upholds outstanding electrical properties. It has a 90 ℃ Operational temperature for normal conductors.
11kV XLPE power cables are designed with single or three circular conductors which are covered with a screened conductor.
11kV XLPE cable gives outstanding performance at 0.6kV to 11kV Voltage. This voltage is in accordance with the international electro technical commission publication (IEC 60502.2).
These 11kV XLPE cables are ideal for indoor or outdoor applications. Also, they are appropriate in cable tubes in water.
These cables are used for direct burial underground because there is very severe mechanical stress present there.
Two British standards BS6622 and BS7835 are used in the production of XLPE cables having 11kV Voltage. These cables are used for providing or transmitting power in various distribution networks.
In these XLPE cables, Aluminum wire armour is used for making single-core cables. And for multicore or 3 core cables steel wire armour is used.
This armouring provides these 11kV cables strong mechanical protection because these are buried direct in the ground.
These 11kV XLPE cables having medium or high voltages are made up of copper conductors. These cables have a semi-conductive screen, XLPE insulation with a semi-conductive insulation screen and a metallic screen with copper tape.
Their outer covering or armour is made up of PVC or steel wire armour.
According to IEC 60502 standard 11kV XLPE cables are most appropriate for voltages 6 to 11kV.

To cut short, 11kV XLPE cables are available in single as well as multi-core structures. In 11kV XLPE cables are mainly comprised of a conductor screen, XLPE insulation, and an insulation screen.
It is made up of compact stranded copper in a spherical shape conforming to BS EN 60228. As the insulation, the semi-conducting compound is joined with the insulation.
XLPE insulation at a temperature of 90-degree centigrade is used. As insulation screen, cold strip able screens are utilized but sometimes fully welded screens are used.
To give earth liability the current path, copper screens are used. As a standard low smoke 0 halogens and sometimes polyvinyl chloride is also used in 11kV XLPE single-core cables.
In Single-core 11kV XLPE cables, a single layer of round aluminum cable is coated.
As an alternative option, on some occasions, medium density polyethylene is also utilized in as a cable’s jacket.
SSG’s cross-linked polyethylene 11V cables are made up to be appropriate for 90-degree centigrade as well as 250-degree centigrade.
