138kV Porcelain Type Indoor, Outdoor Termination

Introduction

Rated voltage 76/138kV YJZWC4(3)porcelain outdoor termination composed of connector lug, stress cone, stress cone cap, porcelain, wiping sleeve and other accessories. The hardware like connector lug have been treated by positive polarity, fastening are made of stainless steel, have good corrosion resistant property, the stress cone adopt imported EPDM rubber injecting formed. Porcelain bushing adopts high strength porcelain, figure is cone, has good pollution resistant and anti-flashover porcelain bushing, sealing with imported sealing ring, ensure the insulation and sealing property. It has advantage of compact structure, superior property, beauty appearance, easy to install and high mechanical strength. Well accepted by all clients.

TYPE

YJZWC3 Type: Suitable for indoor III pollution grade.

YJZWC4 Type: Suitable for outdoor IV pollution grade.

suitable range

●Indoor and outdoor

●Rated voltage/Max voltage:138kV/145kV

●Environment pollution grade: IV grade

●Suitable for cable section:185~1200mm²

^Features

●Porcelain bushing is made of high-strength inorganic material porcelain, it has advantages of superior weather resistant, good anti-tracking, electrical corrosion and drain off water property, ensure the termination can be run in bad weather condition and high pollution zone safety.

●The structure adopts spring promoting cone bracket, keep the stress come closely, to make it localization. The stress cone cap ,to avoid the stress come dipping into the silicone oil, overcome the evil of the stress cone elastic loosing for the material age and bad conductor layer, pro-long the service life of the stress cone.

●The end of porcelain bushing is sealed with imported 0 sealing ring. The top of porcelain bushing adopt milt-sealing structure to prevent leakage water and oil phenomena of the termination porcelain bushing during running, pro-long its service life.
