A, YH5WR-51/134 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. Second, the selection of the user can choose different arrester protected object models, 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.

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! Shanghai Yi Electric Co., Ltd. is well-known in your industry, one of the professional manufacturers of electrical and building electrical accessories, mainly for high-voltage current-limiting fuses, high-voltage load switch, high voltage insulators, high voltage surge arrester research and development and production of domestic and foreign advanced standards, wall bushing, a series of high and low voltage vacuum circuit breakers and other electrical products! Product Name: MOA Model: YH5WR-51/134 MOA Keywords: YH5WZ-84/221, YH5WZ-84/221 MOA manufacturers promise: 2 days shipping, 7 days, 15 days shifting, one year warranty. Four, YH5WR-51/134 MOA MOA MOA working principle is recognized worldwide as the most advanced mine appliances. The structure of the number of films ZnO compress the seal valve arrester porcelain sheath. ZnO valve has a very excellent nonlinear characteristics at higher voltage resistance is very small, you can discharge a large number of lightning current, residual voltage is very low, at a large power grid voltage resistance, leakage current of only 50-150μA, the current very small, can be regarded as non-frequency-wheeling, this is can be made without gaps MOA reasons. Its steep slope and amplitude of the same limited pressure effect of lightning, lightning protection function is completely is its outstanding advantages. In China it is used to produce zinc oxide surge arresters without gaps, operation and practice, which has damaged explosive rate, short life and other shortcomings. The reason for the difference between transient overvoltage tolerance is its Achilles heel. The series gap MOA still unprotected performance benefits gap MOA, while transient overvoltage withstand strong features, is an ideal product weaknesses, combined with China's national conditions and the system can be connected in series 3-35kV gap MOA.
