PRODUCTS

JW6-126/252 type Disconnetor

Description

1.Brief Description

JW6-126/252 outdoor AC high-voltage grounding switch is for high voltage line to make the reliable grounding, in order to make sure the personal safety in the maintenance of busbar and other equipments. Equipped with CSC human mechanism(or CJ11 motor operating mechanism), the electromagnetic lock of CSC human mechanism is supplied to other equipments for electrical interlocking.

2.Main Features

2.1.Straight lun plug-in, advanced design concept, simple and reliable

2.2.The transmission shaft of products use high-quality alloy steel, hot-galvanizing process on surfaces, strong anti-corrosion. Some part of drive shaft adopt composite sleeve, good wear resistance and strong anti-corrosion.

2.3.Products has the characteristic of smooth and reliable operation, small operating force, long mechanical life, etc.

2.4.Reasonable structure, sate and reliabe performance, easy installation and commissioning on-site.

2.5. Long mechanical life: 5000 times

2.6.The transimission part of products is coated with anti-freezing greese, its operating temperature is -60°C~120°C, low temperature operation is not affected.

2.7.The contact surface of the products is Toshiba silver plating technology, the hardness of silver layer is 140HV, enhances the conductivity and wear resistance of its surface.
