Description

Metal-oxide surge arrester(Lightning arrster, polymer surge arr

Technical Performance

The technical performance of metal-oxide surge arrester is accord with IEC******4 and IEEE(ANSI)C*2.*1. The product certification through KEMA Nederland B.V. T&D Testing Services.
Structural Design
The module core design was developing in the early *0s and has over *5 years service experience, with the housing material changing in the early *0s.

The modular single column polymer housing metal-oxide surge arrester design is available up to **0kV systems.

The essential feature of the internal patented construction is the permanent homogenous resin and fiberglass bond over the complete insulating service of the metal-oxide varistor, the arrester module has an inherently high mechanical strength and provides a uniform dielectric at the insulating surface of the metal-oxide varistor.
