Description

Introduce

In order to expand the scope of this type transformer design three different technical parameters to choose from.

In addition.Based on user needs,this type of transformer can be designed for the special specifications of the varied and the measured level and protection level change.

Features

The current transformer is the pillar structure,the use of epoxy pouring full-closed,resistant to pollution and humidity,but also suitable for tropical regions.

Completely closed due to current transformer with epoxy resin casting.

The transformer does not require special maintenance,just on a regular basis to remove surface dirt.

Small size,Suitable for any location,and installed in any direction.
