ABB Medium Voltage MV Surge Arresters
ABB MWK High Voltage Surge Arresters AC 4kV - 44kV
ABB MWK indoor and outdoor high voltage AC surge arresters protect against multiple atmospheric and switching overvoltages including Very Fast Transients (VFT). ABB MWK surge arresters are suitable for the protection of high voltage transformers, cables, motors and other HV electrical equipment.
ABB high voltage metal-oxide surge arresters are renowned for their high performance in both indoor and outdoor installations. The MWK surge arresters are produced with a polymer housing made of silicone. The silicone housing is deirectly moulded onto the active part of the surge arrester, thus avoiding any air volume or air gap inside the housing. cover the complete range of continuous operating voltages from 4-44kV(kV rms), including 6.6kV, 11kV, 15kV, 20kV, 24kV, 33kV, 36kV cable networks and systems.
ABB MWK High Voltage Surge Arrester Advantages
The surge arresters are extremely resistant against overload, thus preventing explosions and subsequential damage to other high voltage electrical equipment in the area. In comparison to other polymeric materials, silicone has the highest resistance against pollution. The silicone used by ABB has proven itself under severe environmental conditions like water, salt fog, sand, industrial pollution as well as UV radiation.
ABB surge arresters are tested according to IEC standard 9904, 1991.
