A 500-kVA transformer is being set up underground at Malleswaram 15th Cross at a cost of Rs 2 crore. The transformer, which will thwart power-related accidents and power-supply snags, is being executed by Bescom and Bruhat Bengaluru Mahanagara Palike (BBMP). Karnataka’s energy minister Sunil Kumar claims it is the first such project in the country.
According to the state energy department officials, the transformer will be built 8ft deep from the road surface. While Bescom engineers are working on electrical details, BBMP is carrying out civil work.
“Western countries have adopted this method, keeping in mind the public convenience and safety. We will be experimenting that for the first time in India here in Malleswaram,” Dr CN Ashwath Narayan, higher education minister and Malleswaram MLA, told TOI.
Engineers: Transformer will be concealed in sump-like chamber
According to a senior engineer of Bescom, “The transformer will be concealed in a chamber which will be under complete a ir-condition system along with fire protection to absorb the heat generated by the transformer. Underground transformers require half the area consumed by overhead transformers. The electrical cost alone would come up to Rs 1.3 crore.”
Sou rces said based on the technical inputs given by TCS, BBMP is working on the chamber. “The structure would resemble a bigger water sump. Citizens can walk over the chamber without hassles. The chamber will be covered with thick concrete walls on all four sides. Along with ventilation, a small passage will be provided for engineers to repair and service the transformer,” explai ned an executive engineer from BBMP.
‘Accidents can be avoided’
Minister V Sunil Kumar said, “The first-of-its-kind project in the country will put an end to transformerrelated accidents. Be it a transformer blast or electrocution, these accidents can be avoided by goingu
nderground. This will come in handy if there is space constraint.” BBMP, as per officials, has finalised bids and submitted them to the government for approval.
