Detailed Description

Main features:

 

       SF6 is the internal insulation medium; CB can be equipped with pneumatic mechanism, DS, ES and FES can be equipped with motor or motor spring mechanism. This type product requires much smaller site work and has the following advantages: 


  1. Stable and reliable interrupting performance: the breaking current can be 67-70kA, using copper-tungsten contact and minimizing the parts number.


  2. Highly reliable operating mechanism: simple structure, plenty of service experience and smaller maintenance work.

 

  3. High quality insulating parts, such as insulator, cylinder and rod, which shall be individually tested by power frequency and PD measurement.

 

  4. Perfect assembly and inspection condition; products can be transported to site as one complete bay, which reduces the site installation work.

 

5. Lower SF6 gas annual leakage rate through self-sealing adaptor.
