VOLTACTIVE provides you the complete encapsulation of primary and secondary winding in epoxy resin which prevents penetration of moisture into windings. Contrary to the conventional dry type transformers, the cast coil transformers are better in respect of impulse voltage withstand strength. The cast resin offers very good protection against adverse ambient conditions. These transformers can work without disruption of service at 100% humidity.
These transformers are generally smaller in dimensions and lesser in weights. The construction and installation cost for the sub-station can be reduced by adopting dry type transformers.
Due to encapsulation of coils with cast resin the coils dimensions are stable & no coil tightening is required to maintain the short circuit strength. Also no check of oil level and electrical insulation/oil is required. This leads to saving in cost on account of maintenance.
Voltactive can manufacture upto 1000KV 11KV/433V with best quality.
