Product Description
Products Introduction:
A surge arrester is an over-voltage limiter that protects power transmission and transformation equipment (transformers, switches, capacitors, wave blocks, transformers, generators, motors, power cables, etc.) from overvoltage damage.It is a power system.The basis of insulation coordination.
The metal oxide arrester with the disconnector composite jacket is equipped with a special insulating plate and mounting bracket.The bolt on the disconnector is directly connected to the bottom of the arrester, and the lower bolt of the disconnector is connected to the ground wire.The purpose of the arrester disconnector is that when the arrester is damaged under abnormal conditions, the power frequency short-circuit current causes the disconnector to act, and the grounding end of the disconnector is automatically disengaged, so that the faulty arrester is separated from the system, and the fault arrester needs to be replaced.To achieve this, the disconnector must have fast acting characteristics and withstand specified current surge and action load capabilities.

Normal operating conditions:
1.Ambient temperature :-40ºC~+40ºC;
2.Radiation of sunlight:Note:The influence of the maximum sun exposure (1.1 KW / square meter) has been considered by the method of preheating the sample in the type test.If there is other heat source near the arrester, the use of the arrester needs to be negotiated by both parties..
3.Altitude:≤1000m;
4.Frequency:48Hz~62Hz;
5.The power frequency voltage applied between the terminals of the arrester for a long time shall not exceed the continuous operating voltage of the arrester;
6.Earthquake intensity below 7 degrees;
Features:
1. Small size, light weight, collision resistance, no loss of transportation, flexible installation, especially suitable for use in switch cabinets;
2. Special structure, integral molding, no air gap, good sealing performance, moisture proof and explosion proof;
3. Large creepage distance, good water absorption , strong pollution resistance, stable performance, and the operation and maintenance are reduced;
4. Uniquely formulated zinc oxide resistors, high capacity, low leakage;
5. The actual DC reference voltage, square wave flow capacity and high current withstand capability are higher than the national standard.
