Weidmann sees growth in Indian business
witzerland-based Weidmann Group, was amongst the several multinational companies that participated in Elecrama 2016. In a brief interaction with Electrical Monitor, a senior spokesperson of Weidmann said that the group’s core business in India was providing insulation to high-voltage oil-cooled power transformers. “The higher the voltage of the transformer, the better chance we have to reach India as a customer,” noted the spokesperson. Weidmann caters to manufacturers of 400kV, 765kV and also 800kV, he said. Apart from supplying insulation components, Weidmann also does consultancy that might involve assisting transformer makers with field calculations.
Weidmann, present in India for over 50 years, operates through Mumbai-based Govik Electricals Pvt Ltd. The local company does not have a manufacturing
Sfacility but is licensed to fabricate insulation parts out of large boards (around 6m x 3m) sourced from the Swiss company. Large power transformers need customized insulation parts in various shapes including cones. Crompton Greaves was an important Indian customer, the official said, adding that there were several others in the clientele as well. Lowvoltage transformer manufacturers were not in Weidmann’s clientele as it was not economically viable to source high-cost Swiss-made insulation for relatively lowend products.
The spokesperson drew parallels between India and China stating that both countries would need extra-high voltage lines to transmit power across long distances that separate power generation and consumption centres. In China, Weidmann has four fabrication lines, he added. On the transmission technology front, the Weidmann official felt that DC lines might be the choice for long-distance high-voltage power transmission as the line losses are lower.
“In earlier years, business was low in India but it is now picking up because of the economy,” the Weidmann official concluded.
