The metal oxide arrester with all-insulated compound coat is a kind of new type over-voltage protector with simple configuration. The insulated wire at the end of high voltage can shape in integration with core of the arrester. Such arrester has good seal performance and high electricity saving strength.
When using the arrester, its inter-phase insulation distance must be guaranteed, the distance should be changes as using conditions, so that creeping distance and inter-phase distance should be increased accordingly. The arrester produced by our company has overcome such disadvantages, which widened creeping distance and narrowed insulation size between arrester bodies, so that they are convenient and flexible which are suitable to different installing environment, especially can be installed in switch cabinets, high-altitude areas and areas heavily contaminated areas with limited space.
