6kV Polymer Surge Arrester Metal Oxide Lightning Arrester
The technical performance of metal-oxide surge arrester is accord with IEC60099-4 and IEEE(ANSI)C62.11.
The module core design was developing in the early 80s and has over 15 years service experience, with the housing material changing in the early 90s.
The modular single column polymer housing metal-oxide surge arrester design is available up to 220kV 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.
