Jiangsu Daqo kfine electric Co., Ltd(KFINE)was investigated by Daqo group Co.,
Ltd(the former Jiangsu Changjiang Electric group Co., Ltd). The company specializes
in developing, manufacturing and selling of low-voltage electric equipment, and has
been given the title of "High-tech Enterprise of Jiangsu".
The company has a strong technical foundation and modern design means. Here
have the good cooperative membership with shanghai electrical apparatus research
institute, Xi'an jiaotong University and Jiangsu University. And the postdoctoral
programs in group corporation plays a vital role in researches and development.
The company concentrates on the technical improvement and introduces successively
various international advanced manufacturing and testing equipments from Germany,
USA, Japan and Swiss. All those provide reliable guarantee for high quality products.
the ACB and NCCB products are listed in "Torch High-tech item of China", and win
many honors from Jiangsu province and Zhenjiang city.
The company has built ERP system and Human Resource administion systerm, and
has passed the ISO9001:2000 quality authentication.
Now, the products designed and developed by the company include: the KFW2 series

With the development of society People's request to the
reliability of power supply are becoming more and more
strict, 2-circuit electric source has been used in many
conditions in order to ensure the reliability of power supply.
So a reliably transfer switch between two circuit electric
KFQ2
sources is required emergently. KFQ2 duplicate power
KFQ2
supply automatic transfer switch is such a new product
designed according to this requirement.

KFQ2 400V KFQ2 is suitable for transferring between two circuit s of
power supply (working power supply, standby power supply
63A 800A
or generated power supply) with rated frequency of AC
KFQ2 50Hz,rated working voltage to 400V and rating current up
to 800A. KFQ2 is switable for important plale where power-
breakering is not allowable such as hospital, mall, bank and
fire protection facilities.
