Surge Arrester is also called over-voltage protector and over-voltage limiter. It is connected in parallel to the front end of the protected equipment. Which protects other electrical equipment from lightning over-voltage, operating over-voltage, and power frequency transient over-voltage impact.

Technical features
The Arrester is mainly composed of insulating housing (composite or ceramic material), resistors, and end accessories.
Product advantages
- The resistors are manufactured with high-quality raw materials and strict processes. The comprehensive performance of the resistors has reached China’s advanced level, especially the current capacity, high current impact, and residual voltage ratio performance have reached China’s leading level.
- The use of duration encapsulating materials or epoxy composite casing fundamentally solves the problem of product failure caused by moisture intrusion. Even in a high-temperature environment with a humidity of more than 90%, there will not be any failures.
- Silicone rubber material is highly hydrophobic, it can prevent rainwater from forming continuous channels and prevent any pollutants from accumulating during use. Make the product corrosion-resistant and cut off the leakage current path. Moreover, the flame retardant and self-extinguishing properties of the material can realize the product’s cleaning-free function.
