Product Introduction

Our company’s indoor high voltage AC insulated switch series (hereinafter referred to as insulated switch) are three-phase AC indoor device with the rated voltage of 12kV and the rated frequency of 50Hz, used for opening and closing the circuit when there is voltage while no load. This product conforms to GB1985 national standard. (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 insulated 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.
