ARRESTER

ARRESTER We are specialized in producing 0.28~ 220kV A.C System metal oxide surge arrester, electric railway surge arrester with porcelain and polymeric housing for protection electrical system and electric railway against over-voltage.
Meanwhile we have tried our best to improve technology by ourselves, our surge arresters have passed KEMA type test and got the test report.
Routine test items: Our surge arresters are produced according to IEC 60099-4 and ANSI standard, also for every piece of arresters, we will perform routine test items specified in IEC.
Features: Excellent protective performance: The metal oxide varistor have good response to steep front surge, excellent volt-ampere characteristics and high discharge capacity, which provides a very consistent protection merit at steep front surge, lighting surge and swithing surge and enhance protective capability.
Reliable pressure relief function: the unique pressure relief device worked out upon latest achievements in this field, features precise operation, safely and reliability, which ensure MOA to release internal excessive pressure in any event to minimize fault effect.
Unique sealing device: Excellent MOA to sealing is insured during its service life by weathering proof, thermal-resistant and well elastic sealing gasket and unique sealing device as well as high sensitive leakage detection-helium mass spectrometry.
