 LZW-10 current transformer

Description and meaning of model

The current transformer for outdoor epoxy casting insulation fully enclosed structure .Applies to the rated voltage of 10kV and below ,rated frequency 50Hz or60Hz outdoor power syatem for the current use of energy measurment and relay protection.

Characteristic of structure

The current transformer is a user outside the epoxy resin as a whole casting,arc resistance,UV resistance,aging resistance,long life characteristics.Core made of high quailty magnetic material,and annealing treatment ,primaary and secondary windings and core are cast in epoxy resin.Has excellent insulating properties.The first outlet at the top of the casting body,the qualifying mark for the P1,P2.Measuring winding outlet side for 1S1,1S2,winding protection qualifying mark for 2S1,2S2,the transformer is subtractive polarity,the second wiring part of the protective cover.And anti-tamper measures.The base has four mounting holes for installation.
