LT Power Cables

LT-POWER CABLELT Power Cables: LT Cable is of 1100 V, which is generally used in the domestic purpose for around 230 V and in industrial purpose for 430 V. Normally construction for LT power is 3.5 core where the 3 power cores are identified by the pigmented compound Red, Yellow and Blue and neutral core is Black which does not contain power but utilized for earth in and fault protection purpose.

The power core is also called the main cores and neutral core, which is of reduced cross section is also called half core.

ABC aluminium conductors are mainly XLPE insulated and each core are twisted round a aluminium alloy bare stranded conductors called MESSENGER. The Messenger conductor facilitates suspension of the cable on hooks and clamps in street lighting poles. Hooking and pilferage of power is prevented. There is also vast advantage of continuous power supply in the event of storms and blizzards.

Installation of AB Cable is simpler and much cheaper than the underground cables. Cable accessories are also cheap.The installation time is much less. ABC Cables are manufactured as per Indian Standards and Overseas Specification.
