Silicone Rubber Railway Composite Insulator

Integral wrist arm support composite insulator normal working conditions:

1. Altitude: ≤ 1500 meters

2. Ambient temperature: -40 ℃~ + 40 ℃;

3. AC power frequency: ≤ 100Hz

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

5. Earthquake intensity: 7 degrees and below

Structural features of integral wrist arm support composite insulator:

1. Small size and light weight, it is about 1/5 to 1/9 of the porcelain insulator of the same voltage level, which is resistant to collision and easy to transport and install.

2. High mechanical strength, large tensile load, reliable structure, stable performance, and large safe operation width.

3. The overall wrist arm support composite insulator has superior electrical performance, silicone rubber has good hydrophobicity and mobility, strong anti-fouling flashover ability, can operate safely in medium and dirty areas, and does not require manual cleaning, and can be free of test zero value maintenance.

4. The integral wrist arm support composite insulator has anti-brittleness performance of acid, alkali and heat aging resistance, strong shock resistance, and will not occur.
