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. 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:≤2000m;4.Frequency:50Hz or 60Hz;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.Technical
