Wind power 35kV zinc oxide lightning arrester without gap

Wind power 35kV zinc oxide lightning arrester without gapFunction:
The lightning arrester is connected between the cable and the ground, usually in parallel with the protected equipment. Lightning arresters can effectively protect communication equipment. Once abnormal voltage occurs, the lightning arrester will activate and provide protection. When communication cables or equipment operate at normal operating voltage, lightning arresters will not work and are considered as open circuits to the ground. Once high voltage occurs and endangers the insulation of the protected equipment, the lightning arrester immediately operates to direct the high-voltage surge current to the ground, thereby limiting the voltage amplitude and protecting the insulation of communication cables and equipment. After the overvoltage disappears, the lightning arrester quickly returns to its original state, allowing the communication line to work normally.
Therefore, the main function of lightning arresters is to attenuate the invading flow waves through parallel discharge gaps or nonlinear resistors, reduce the overvoltage value of the protected equipment, and thus protect communication lines and equipment.
Lightning arresters can be used not only to protect against high voltage generated by lightning, but also to protect against high operating voltage.
The function of a lightning arrester is to protect various electrical equipment in the power system from damage caused by lightning overvoltage, operational overvoltage, and power frequency transient overvoltage. The main types of lightning arresters are protective gap, valve type lightning arrester, and zinc oxide lightning arrester. The protective gap is mainly used to limit atmospheric overvoltage and is generally used for the protection of incoming lines in distribution systems, power lines, and substations. Valve type lightning arresters and zinc oxide lightning arresters are used for the protection of substations and power plants. They are mainly used to limit atmospheric overvoltage in systems of 500KV and below. In ultra-high voltage systems, they will also be used to limit internal overvoltage or serve as backup protection for internal overvoltage.

Wind power 35kV zinc oxide lightning arrester without gapPoint and Principle:
AC gapless metal oxide surge arresters have excellent nonlinear volt ampere characteristics, good response characteristics, no freewheeling, large current capacity, low residual voltage, strong ability to suppress overvoltage, pollution resistance, anti-aging, free from altitude constraints, simple structure, gapless, tight sealing, long life and other characteristics.
This lightning arrester exhibits a high resistance state under normal system operating voltage, with only microampere level current passing through. Under the action of overvoltage and high current, it exhibits low resistance, thereby limiting the residual voltage at both ends of the lightning arrester
