polymer surge arrester

Over-voltage arrester is a limiter, is the protection of power transmission equipment (transformers, switches, capacitors, filter resistance, transformer, generators, motors, power cables, etc. ) from over-voltage damage to electrical appliances, insulation coordination of power system is basis.

MOA of the main components of metal oxide film resistor, is the company adopts the international advanced technology, manufacturing improvements by optimization with a non-linear (V characteristics) excellent, steep wave response to a good through-flow capability and resistance excellent performance characteristics of aging and greatly enhance the protection of surge arresters and reliability.

Jacket composite metal oxide surge arresters, the use of the overall injection molding, two encapsulation techniques, good sealing performance, explosion-proof performance, filthy-resistant, corrosion-resistant, anti-aging, small size, light weight, easy to install and maintain.

Porcelain jacket MOA, the structural characteristics of a good, long-lasting sealing properties, the potential publication of uniform and reliable pressure release device.

The main types are:

Communication system using composite jacket MOA 1: Low use; 2: 3 KV ~ 220KV power distribution and power plant use; 3: Transformer with neutral point; 4 motor; 5: Parallel compensation capacitor; 6: Use of electrified railway; 7: AC Transmission Lines; 8: AC transmission lines are in series with composite jacket MOA gap; 9: AC Transmission Line Composite jacket with metal oxide surge arresters without gaps; 10: Liquid silicone rubber (LSR); 11: With out-type; 12: Belt-type compound from the coat of metal oxide surge arresters without gaps; 13: Series gap; 14: Live-style overhaul.

Communication system using porcelain jacket MOA 1: Low-voltage communication systems; 2: 3 KV ~ 220KV AC power distribution and power plant system with; 3: 3 KV ~ 35KV systems with series gaps; 4: Transformer neutral point; 5: Electrical used; 6: Parallel compensation capacitor; 7: Use of electrified railway; 8: DC system free space.
