The metal zinc oxide arrester is the most advanced over voltage protection equipment in the world at prestent, which is to be applied to AC electrical systems with AC frequency 48~62HZ, 35kv and below for over voltage limitation, in order to protect the insulation of various electrical equipments in the electrical system from the damage of lightening over voltage or operation over voltage. It is one of the cirtical protection equipment that ensures the safe action of electrical system. It has the following features: the metal zinc oxide arrester adopts zinc oxide resistance sheet with excellent volt-ampere characteristics as the chip, which has many advantages over traditional carbon silicon arresters, such as quick action, good steep wave characteristics, low remain voltage, large flux capacityy, no following flux, simple structure, light, good reliability, strong anti-pollution capability and easy maintenance, the compound sleeve type also has a cover, which is made of silicon rubber through inegral press molding, It is well sealed without gas slot, and is also humid and explosion resistant, which is especially applicable in switch bar.
The main technical performance of this product is in conformity with the standard GB11032-2000 and JB/T8952-1999.
