POLYMERIC HOUSING SURGE ARRESTERSThe INZP arrester offers all the advantages of a metal oxide distribution arrester in light-weight, low profile polymeric housing designed for either indoor or outdoor overhead aplications. The polymeric housing eliminates the problem of chipped ro cracked porcelain that can occur with rough handling or shipping. Reduced weigh is ideal for easy installation. The INZP is approximately 1.5 kg lighter than is INZ arrester porcelain equivalent for the 10 kV rating and 3.8 for the 27 kV rating.The failure mode of the INZP arrester is less severe than that of porcelain housed units. When violent failure mode of porcelain housed arresters occurs, it does so when the internal arc from excessive fault current causes thermal fracture of the porcelain housing and the hot gases created by the arc explodes the porcelain fragments in all directions. The INZP with its polymer housing, will split open suring failure conditions to relieve the internal pressure.
