AC High Voltage Single Pole 12kV Disconnect Switch 

 PRODUCT  FEATURES

     1.  High quality material

     All fittings are not only reasonably, intergrally designed and fine fabricated, but also made of high quality materials.  Their over 15um silver coating for all conductive parts, high quality hot galvanized coating and stainless steel material and ensure a long service life of the product.

     2.   High strength anti-bird insulator

      

     3.   Manipulating and locking device

     Composed of cast precisely copper elements the device can be manipulated at any angle. The simple and unique copper locking device and connecting elements made of stainless steel ensure stable and reliable locking and unlocking in long term.

     4.   Conduction circuit structure

     Made of high conductive copper material and silver-plated on the surface for preventing from oxidation the structure presents reasonable arrangement, large conductive contact area, small contact resistance and load capacity for current more than 1000A.
