DNK (Xiamen) Electrical Co., Ltd. [China]

AC High Voltage Open Type 10kv Disconnecting Switch DNK have the most innovative technology in the international.

    AC High Voltage Single Phase 10kv Disconnecting Switch

     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.   Post Insulator:

     High strength anti-bird insulator be made of porcelain, epoxy resin or silicon rubber.

     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.

     5. Copper knife blade

     Double-layered, cold-drawn and round edged.
