LZZBJ9-36/250W2G1（L）current transformer adopts indoor epoxy resin casting and pillar structure. The product can be applied to indoor power system of rated frequency 50Hz and rated voltage 40.5KV or below, used for current & electric power measuring and protective relaying, and applicable to mid-set switchgear or other type switchgear. This product possesses the characteristics of high power and thermal stability parameter, large secondary output capacity and stable insulation performance. More complex product can be produced according to the requirements of the customers.
The secondary terminal of the current transformer is equipped with a wiring protective cover. There respectively is one hole on the front and two sides of the protective cover for the secondary line. Also the protective cover is fixed by seal screw with the anti-tampering function.
