lightning arrester

Description

Detailed Product Description 1.KEMA certification; ********1 quality management system; ***** test laboratory; ***** supply of product components. Metal-oxide surge arrester(Lightning arrster, polymer surge arrster) 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. Advantage (CANTOR BRAND) - Low residual voltage - Long protection distance - High energy input capacity - Stable U-I characteristics even after multiple strokes - Proof against ageing - Explosion and shatter-resistant design - Pollution resistant and UV-stable - Housing resistant to rough handling - Maintenance free - Stable against shock and vibration - High mechanical resistance Main Technical Para meter of Polymer Housing Metal-oxide Surge Arrester (YH*0W**1kV E3) 1.
