Lightning arrester for transformer neutral point type HY1.5W
Description:
The composite jacket metal zinc oxide arrester is a high-tech
product of the international 90s. It adopts integral silicone
rubber molding, has good sealing performance, excellent
explosion-proof performance, pollution-free cleaning, and can
reduce the occurrence of foggy wet flash, corrosion resistance and
aging resistance. Small size, light weight, collision resistance,
easy to install and maintain
Used to protect the transformer neutral point of the corresponding
voltage level from atmospheric overvoltage and operating
overvoltage
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. The creepage distance is large, the water absorption is good,
the pollution resistance is strong, the performance is stable, and
the operation and maintenance are reduced;
4. Uniquely formulated zinc oxide resistors, high capacity, low
leakage;
5. Realized DC reference voltage, square wave flow capacity and
high current withstand capability are higher than national
standards
Use environment:
1. Ambient temperature is -40 ° C ~ +40 ° C
2. The altitude does not exceed 2000m
3. Power frequency is 48Hz ~ 62Hz
4. The maximum wind speed does not exceed 35m/s
5. Earthquake crack 7 bottom and below
6. Long-term applied voltage does not exceed its maximum continuous
operating voltage
