Description

Condenser wall bushing with CT

FCRG-L dry-type condenser wall bushing with current transformer is based on the following principles.:
A. Electromagnetic induction principle static transmission of AC electrical energy and change of AC.
B. Reduce the high voltage gradually through the capacitive voltage division principle. The lead wire of the capacitive terminal is led out through the capacitive terminal hole on the flange and connected to the ground bolt.
Thus, the high-voltage lead wire can be safely passed through the wall or floor, etc., to play the role of insulation and support the diversion of the above two principles made of the device.

Structure

FCRG-L wall bushing with CT is divided into two types: integrated and separated type. It is composed of the primary winding, heat shrink tube, silicone rubber sheds, grading shield at both ends, shell, secondary winding, and conductive clamp, etc. Pollution class： Ⅱ、Ⅲ、Ⅳ。
