New way to wash high-volt cables

After successful trials in Delhi, washing high-voltage overhead electricity wires from helicopters began in the NCR on Tuesday.
Officials launched the latest technology by washing a 400 KV High Transmission line at Samaypur village in Faridabad without shutting down the lines. “Earlier, we would need a lot of people to do the same job over a fortnight and would need to disrupt power supply for long hours,” said Atul Mittal, Chief Manager, Power Grid Corporation, which has devised this method in association with the state-owned Pawan Hans Helicopters.
Power Grid has brought in experts from New Zealand to oversee the operation. Power Grid plans to replicate it in the whole of NCR. “This technology is useful in North India because fog and pollution here often trips electricity transmission lines in winter, causing massive losses,” he added.
Industrial smoke, vehicle emission mixed with high quantity of dust due to wide spread construction work in Delhi and the NCR have wreaked havoc on overhead transmission lines.
