Product Introduction

Our company’s indoor high voltage AC earthing switch series (hereinafter referred to as earthing switch) are suitable for three-phase AC indoor earthing device with the rated voltage of 12kV and the rated frequency of 50Hz. The switches conform to requirements of both GB1985 High Voltage AC Disconnectors and Earthing Switches and IEC129. They have various advantages including advanced design, reliable technical performance, simple structure and easy installation. The switches can be equipped into different kinds of high voltage switchgears. For example, the switch can be used as artificial earthing of manufacturing network during overhaul of high voltage electrical equipmentto protect people against electric shock. (We can gear our switches to the special environmental conditions in accordance with the requirements of clients.)

Product Features

1. Main conductors in our high voltage earthing switch series adopt T2 copper one-time shaping technology, increasing the flow capacity of the current.

2. The switch uses special porcelain as insulating material, greatly enhancing the insulation level and mechanical strength and making the operation more safer.

3. The switch can be operated by hand or automatically by electricity with advantages of light operation force, simple structure, easy maintenance and no pollution on environment.
