LZZBW-10 Outdoor Current Transformer

Description and meaning of model

LZZBW-10 Outdoor Current Transformer is especially suitable for outdoor environment, with rated frequency of 50Hz or 60Hz and rated voltage of 10kV. This transformer is mainly used for electric energy metering, current measurement and relay protection to ensure stable operation and efficient management of power system.

Characteristic of structure

This product is epoxy resin casted, with these characteristics of arc-proof, anti-ultraviolet radiation, aging-proof, long life. The iron core adops quality high permeability magnetic and being annealing treatment. The iron core, the primary and secondary windings are all casted in the epoxy resin.Therefor the insulativity is excellent. The signs of the primary outlet which is on the top of the casting body are P1 and P2. The signs of outlet of the winding (measuring class)are 1s1, 1s2. The sign of outlet of the winding (protection class) are 2S1 and 2S2. The transformer is subtractive polarity. And the secondary connection has protection cover and avoid being stolen. On the base there is four mounting holes for installation.
