My company production of 10kV, KYN92A type minitype armored shift type metal closed switch equipment, specifically for the upgrading of the current widely used in the national grid kyn28 type switch cabinet replacement products, compared with traditional kyn28 switch cabinet, has the following outstanding characteristics:

1) small size. Than the KYN28 volume reduction of 52%, covers an area (including the operating space) reduced by 50%. (KYN92A switchgear: invention patent)

2) using dry insulation technology, environmental protection design, can completely replace the use of SF6 gas products, ease of operation and maintenance.

(3) the mechanical life is 30 thousand times (10 thousand times of the traditional product) with the miniaturization of the ZN145-12 type pole post. (ZN145 circuit breaker: invention patent)

4) using the latest cooling technology. 3150A products without fan cooling, by its own cooling structure and technology to meet the requirements of the operation. (invention patent)

5) application. Can be in the civil building (indoor) and outdoor open and close station (outdoor) operation, and has low temperature operating capacity (-40 C).

6) stable and safe operation. The product in 2008 began to put into operation, users are mainly for China Southern Power Grid, Inner Mongolia Electric Power Corporation, Shanxi electric power company, Liaoning province power company, Jilin province power company and user engineering and industrial users substation in a large number of applications already achieved significant operational performance. In 2011 in Liaoning Province, Yingkou old substation and sports substation put into operation, stable operation, safe and reliable. Products currently operating in the power grid has more than 20000 units (surface).
