Power System Protection Surge High Voltage 11kv Arrester at Outdoor 132kV Silicon Metal-Oxide-Lightning Arrester Price

Metal oxide arrester

The metal oxide arrester adopts an oxygen-zinc resistor with excellent nonlinear volt-ampere characteristics. Therefore, compared with the traditional silicon carbide arrester, the protection characteristics of the arrester, lightning wave and working wave are greatly improved. In particular, zinc oxide resistors have good slope response characteristics, no delay to steep slope voltage, low operating residual pressure, and no discharge dispersion. Therefore, it overcomes the shortcomings of the steep discharge voltage caused by the inherent steep discharge delay of the silicon carbide arrester, the large dispersion of the working wave discharge and the high working wave discharge voltage, thereby protecting the margin of the slope. And greatly improved the operation wave. Moreover, in terms of insulation coordination, it can achieve steep slopes, lightning waves, and the protection margin of working waves is almost uniform, thereby providing better protection for power equipment, thereby improving the reliability of protection. Zinc oxide surge arresters have the ability to absorb lightning overvoltage, operating overvoltage and power frequency transient overvoltage.
