Product Name: MOA Model: HY5WZ-7.6 / 27 MOA Keywords: MOA HY5WZ-10/27, MOA HY5WZ-10/27 arrester manufacturers promise: two days delivery, seven days package back, 15 days replacement, one year warranty. A, HY5WZ-7.6 / 27 MOA Description: .... Y MOA HY5WZ-10/27 arrester is used to protect power plants, substations AC electrical equipment from atmospheric over-voltage and voltage spikes. Arrester is a device of substation equipment to be protected against lightning surge attack. When passing along the road to the substation lightning surge arrester exceeds the level of protection, surge arresters first discharge, and a good conductor of lightning current through security into the earth, to make the use of grounding lightning voltage amplitude limit is below the level of lightning surge protection devices, make electrical equipment to be protected. Arrester has its development can be divided into: protection gap - is the simplest form of surge arresters; tube arresters - is a protection gap, but it self-extinguishing after discharge; valve-type arrester - a single discharge space is divided into many short series gap, while increasing the varistor improve the protection of property; magnetic blow arrester - use of magnetic blow spark gap, improve the interrupter ability, but also has the ability to restrict internal over-voltage; zinc oxide arrester - ideal for use zinc oxide valve voltage characteristics (nonlinear high, that large current resistance characteristic was low, limiting the voltage on the arrester in the normal frequency voltage was high resistance characteristics), with No gap, no freewheeling residual depression, etc., but also limits the internal over-voltage, are widely used. Two, HY5WZ-7.6 / 27 MOA MOA Product structural features 1, reasonable design, novel structure, reliable technical performance, compact, lightweight, flexible installation, high tensile strength, resistance to impact, transport without damage; 2 , citing the advantages of silicone rubber coat metal oxide surge arresters, the overall molding a shape, has a good seal, stain, explosion-proof, moisture resistance, high dielectric strength, thermal performance, with greater overvoltage energy absorption capability. Three, HY5WZ-7.6 / 27 MOA use conditions: a) suitable for indoor and outside; b) Ambient temperature -40 ℃ ~ + 40 ℃; c) altitude less than 3000m (porcelain formula does not exceed 1000m); d) Power frequency not less than 48Hz, not exceeding 62 Hz; e) long-term frequency voltage is applied between the terminals of the arrester does not exceed the arrester continuous operating voltage; f) seismic intensity of 8 degrees and the following areas; g) Maximum wind speed does not exceed 35m / s. Four, HY5WZ-7.6 / 27 zinc oxide lightning arrester selection Users can choose different types of objects to be protected, and on the use of different places can be used and pollution prevention and plateau. To meet the needs of the market, I plant non-standard products can be designed according to user requirements.

Seven Info I 110kV, 220kV line composite jacket arrester has passed the National Insulator arrester inspection center type test, and outstanding performance. I am using a unique ring mandrel through the resistor and the ends of the gold with the design and reliable sealing process directly crimped, it has a tensile strength of suspension composite insulators. Flexible fittings at both ends configured to avoid stress on joints of each arrester by the wind swing. Model if the picture is inconsistent, please call to confirm!
