A, Y HY5WR-48/125 MOA is a common arrester also known as: surge arrester. Arrester is a device substation equipment to be protected against lightning shock attacks. When passing along the road over the substation lightning surge arrester level of protection, surge arresters first discharge, and a good conductor of the lightning current through security into the earth, grounding devices make use of lightning voltage amplitude limit is below the level of lightning surge protection devices, so electrical equipment to be protected. Its development has arrester can be divided into: protection gap - is the simplest form of arrester; tube arresters - is a protection gap, but it self extinguishing after discharge; valve arrester - a single discharge space is divided into many short series gap, while increasing the nonlinear resistance, improved protection performance; magnetic blow arrester - use a magnetic blow spark gap and improve the interrupter ability, but also has the ability to restrict internal overvoltage; zinc oxide arrester - use of zinc oxide valve ideal voltage characteristic (non-linear high, i.e., at high currents was low resistance characteristic, limiting voltage arrester on, in the normal form of the high frequency voltage resistance characteristics), having no gap, no freewheeling residual depression, etc., but also limits the internal over-voltage, are widely used. Second, the MOA product structure features 1, reasonable design, novel structure, reliable technical performance, compact, lightweight, flexible installation, high tensile strength, resistance to impact, transport without damage; 2, a reference to the silicone rubber coat metal oxide Advantages arrester, the overall molding a shape, has a good seal, stain, explosion-proof, moisture resistance, high dielectric strength, thermal performance, with a larger over-voltage energy absorption capacity.
