This article explains electrical power cables used in construction works complete with supply, installation, testing and commissioning of High Voltage (HV) and Low Voltage (LV) cables. All cables shall conform to standards of IS 7098-1973, IS 1554-1976 and wiring cables to IS 694-1977 however, contractor shall comply with the latest or superseded versions of IS/BIS to be used for the complete work.
Electrical Cable Laying
Most Construction projects requires underground cabling system for its power supply, some times High tension system too. The architects and builders are least bothered about how this cables routed to the premises and equipment. If electrical professionals pointed out the feasibility, the aesthetics of the project would touch to the intended level.
