22kv silicone rubber insulators

22kv silicone rubber insulators shall be designed to meet the high quality, safety and reliability and are capable of withstanding a wide range of environmental conditions.

22kv silicone rubber insulators

This specification covers the design, manufacture, testing and supply of 11KV / 22KV / 33 KV Composite Insulators. The composite insulators shall be of the following type: Long rod insulators for conductors in tension application at angle / cut points the insulators shall be of tongue & clevis type.

SYSTEM PARTICULARS:
Nominal System Voltage 11 kV 22 kV 33 kV
Corresponding highest system Voltage 12 kV 24kV 36 kV
Frequency 50 Hz with 3% tolerance
Neutral earthing effectively grounded

The insulators should withstand the conductor tension, the reversible wind load as well as the high frequency vibrations due to wind. Glass fibers shall be Boron free electrically corrosion resistant glass fiber or Boron free E-Glass and shall exhibit both high electrical integrity and high resistance to acid corrosion.

Insulator shall be suitable for both the suspension and strain type of load & shall be of tongue & clevis type. The diameter of Composite Insulator shall be less than 200 mm. The center-to-center distance between tongue & clevis shall be max 300 mm for 11 kV, 450 mm for 22 kV & 550 mm for 33 kV composite Insulator.

22kv silicone rubber insulators consist of good self-cleaning properties.
