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.
