Description

Introduce

For rated voltage of 10kV,rated frequency of 50Hz power line current,energy measurment and relay protection in use.

This product is completely closed product in the original old LQJ-10 on the basis of an improved design can completely replace LQJ-10 products,its most important feature is to overcome the old products can not do the 0.2S,0.5S,and problem,and a rated current extends to the 1000A.

Features

This type of transformer core and a secondary winding is all sealed in epoxy resin cast body is fully enclosed structure.

With excellent insulation properties and moisture resistance,to overcome the LQJ-10 shortcomings.

With light weight,small size,suitable for installed in any position in any direction.

The base mounting bar for installation.
