LZZB9-35 Casting Resin Indoor High Voltage Current Transformer

Description and meaning of model

LZZB9-35 Casting Resin Indoor High Voltage Current Transformer is an epoxy resin casting high voltage current transformer designed for indoor environment. Its rated voltage is 35kV and it is suitable for energy metering, current measurement and relay protection in power system. The transformer adopts epoxy resin casting process, has excellent insulation performance and moisture resistance, and can operate stably in harsh indoor environment.

Characteristic of structure

This type of transformer is fully enclosed structure, usingannular iron core and the annealing treatment.The iron core,primary and secondary windings are casted with epoxy resin.Due to strengthen insulation, the transformer can work well in wetcondensation and impurity level ll . There are four holes for instal-ation on the base.
