Product Description

LZW-10 current transformer

Description

This current transformer is full enclosed and prop shape product. It is used for metering electric energy and current, relay protetion in the electric power system up to rated frequency 50Hz or 60Hz and rated voltage 10KV. The transformers can be executed according to the standards IEC185 and GB1208—2008.

Type description

Construction

The type of current transformer is a fuII enclosed and prop shape product. lt is made by outdoor resin(made)in seitzerl and Ciba, the byp is cw5873. The product has much merlt, such as electric arc resistances, ultraviolet ray and agInq resistance, long working time, long creepage distance,little partial discharge and large caliber of resIstance to ever-voltaqe,etc. The primary winding , secondary winding and core are made up together and poured in the cast. The primary winding's terminal, P1 and P2, is on the product, and the secondary Winding's terminaI, S1 and S2, is Ieaded out underside of the product.

Use condition

1. Ambient temperature: -25°C~+40°C, if required, it also can be -40°C
2. Pollution class :IV
