Electric Power Line Material Metal Oxide Polymer Silicone Surge Arrester Iso9001
0.28kV~500kV Surge Arresters' Characteristics:
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 large
in 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.
Features:
1. Compact and Lightweight
2. Extremely Safe Pressure Relief Performance
3. Superior Performance against Environmental Contamination
4. Directly Molded Structure
5. Compliance with International Standards(IEC60099-4)
6. Simple Support Structure
7. Manufactured at Advanced ISO-9001 certified facilities
Apply to:
1. Distribution networks
2. Transmission line
3. Substation
4. Railway power station
5. Alternator and electromotor
