Product Description

As a special accessory of the surge arrester, the insulating mounting bracket plays the role of insulation and fixed support for the installation of the surge arrester, so that the surge arrester can be effectively and firmly installed on the power cross-arm. And after the lightning arrester is installed, the required disconnector can be installed under the insulating mounting bracket.

Product Features

1. Overall molding, good sealing performance, special structure, moisture-proof and explosion-proof;

2. Good heat dissipation performance and large overvoltage absorption capacity;

3. Small size, light weight, flexible installation and collision resistance, high mechanical strength, no damage during transportation.

4.Excellent insulation performance and efficient hydrophobicity;

5. It is suitable for installation in transmission lines with low lightning resistance level and high lightning trip rate: arid hills and mountainous areas: towers with high grounding resistance, large-span river-crossing towers: high operating overvoltage, it is necessary to enter the substation. Previously restricted occasions: Severely polluted areas.

Ambient conditions for use

1. The ambient temperature is -40ºC~+40ºC:

2. The altitude does not exceed 2000m (it should be stated when ordering in plateau areas):

3 The power frequency is 48Hz~62Hz;

4. The maximum wind speed does not exceed 35m/s;

5. Areas with an earthquake cracking degree of 7 degrees and below;

6. The arrester is allowed to swing. According to the tower shape, consider the suspension method and the seat pile method.
