mv composite metal oxide surge arrester without gapsMain
features:1. The Core column applied winding structure, Polymer
Housed core pillar molded on the core column, with almost no
internal air gap, and outstanding sealing performance Simple in
structure, small in size and light in weight. 2. Polymer
Housed with silicone rubber, explosion-proof ZnO varistor as the
core component is largein flow capacity.3. International standard
IEC 60099-4 and ANSI 62.22, and with high reliability. With fully
insulated tops, the product can be applied to the complete cabinet
installation, which can reduce the designing size of
cabinet. 4. Products with detachment device can provide
signals for quitting operation when failure occurs,avoiding
arrester explosion, and it is maintenance-free. 5. Polymer
housed products with a six CTI level, creepage distance meets the
requirements of IV level in heavy pollution areas.Technical
