FCRG composite capacitive wall bushing

Introduction

FCRG composite capacitive wall bushing gradually reduces the high voltage through the principle of capacitive voltage division, and the capacitive terminal lead wire is drawn from the flange, and connected with the grounding bolt. So that the high voltage lead wire safely through the wall or floor, etc., It plays the role of insulation and support diversion equipment.

Structure

FCRG composite capacitive wall bushing is composed of the primary winding, housing, current carrier contactor, capacitor core, silicone rubber sheds, flange, and contactor clamps. The main insulation inside is divided into composite film capacitive insulation and rubber-impregnated fiber capacitive insulation. The main insulation outside is divided into high-temperature vulcanized composite rubber and porcelain. which can meet the needs of different users. There is a measuring tap on the flange. When partial discharge and dielectric loss factors are measured, it is turned on and used. It should be reliably grounded during normal operation. The two ends of the product are the cable clamps.
