Product Description

The working principle of the protector: The core component of the product is the cable sheath protector, and the protector is composed of an oxidation resistance sheet with excellent nonlinearity. In the normal working state, the resistance piece has a high resistance value, and when the overvoltage wave is immersed, the resistance piece has a low resistance value. Even if a large current flows, the voltage value across the protector is still limited within the allowable range. It effectively protects the insulation of the outer sheath of the cable and prevents it from being damaged by overvoltage.

Scope of use:
The product is applied to the direct grounding of the metal sheath of the 35-220kV high-voltage cable system;
The conductor cross-section range of the grounding cable is 120-400mm².

Normal use conditions:
a. Ambient temperature -40 ºC -40 ºC;
b. The altitude does not exceed 1800 meters;
c. The power frequency is 50Hz.
d. Application 35-220kV high voltage grounding
