Send EnquiryFrequently Asked Questions — HT / LT Cable Laying & Jointing
Got questions about electrical contracting in Chennai & Tamil Nadu? Here are clear answers.
What is the difference between LT and HT cable laying?
LT cables (1.1kV) supply power from main panels to machinery and sub-DBs. HT cables (11kV/33kV) bring high-voltage grid power from utility lines to transformers and VCB switchgear rooms. HT cabling requires specialized heat-shrink termination kits and stringent Hi-Pot testing.
Do you supply heat-shrink jointing kits and glands?
Yes, we supply and install reputed ISI/IEC-approved heat-shrink jointing kits (Raychem/3M equivalent), brass double compression glands, and heavy-duty lugs.
