MOA is one of the most advanced over-voltage protection, and is the
basic coordinate insulation device of power equipment. Its
advantage includes short response time, flat voltammetry, low
residual depression and high flow capacity. Besides its
performance, stability, longevity, simple structure makes it be
widely used in the generation, transmission, substation and
distribution systems to prevent the insulation of the electrical
equipment from over-voltage damage.
The 0.22 ~ 220 kV voltage levels of all sizes and types of
composite ceramic coating MOA is produced following country’s
corresponding standard. The product has reasonable design and novel
structure, and is of high performance, good quality and variety.
Users can also make special requests for their arrester.
