In the capital, overhead power lines are fast becoming a thing of the past with the Kerala State Electricity Board (KSEB) replacing them with underground cables.
The KSEB is in the process of laying underground (UG) cables on additional stretches, totalling 440 kilometres and installing 700 Ring Main Units (RMU), the basic tool for automating the distribution system, for ensuring ‘almost uninterrupted supply’ in the city.
‘’The work of laying the UG cables is in progress,’’ the KSEB representative told the Commission at a hearing on the estimates submitted by the KSEB for installing RMUs. Currently, Thiruvananthapuram has in place 650 km of UG cables and 1,700 RMUs, he said.
Kochi has 365 km of UG cables in place and Kozhikode, 309 km, at present. The two cities stand to get an additional 300 km and 236 km respectively.
The cables are being laid in the three cities under the World Bank-aided city schemes, and the centrally-funded APDRP and RAPDRP schemes.
UG cables eliminate the need for overhead 11 KV lines and related structures, ensure improved safety, supply reliability and customer care and reduction in power loss, KSEB officials said.
Along with RMUs, the UG network promises easier fault detection and isolation of the faulty stretch, automated management and almost uninterrupted supply.
