High medium voltage electric switch gear control panel
1: XGN2-12 is mainly used for power reception and distribution of 3-6KV-12KV 3 phase AC 50HZ indoor electric system
Specially suitable for working conditions where frequent operations
2: the production is strictly designed according to I standard,also suitable for frequency Shizuku and dirty working conditions.
3: Successfully widely used by Three Georges project, national engineering designing institute, mining company, cement mill, stell mill,sugar factory,wood industry, chemical industry, city planning, and other place with big power motor and high electric consume place.
4: KYN28-12 removable AC metal-clad switchgear (short for panel as below) is a new product. It will be a substitute for old fashioned metal-enclosed switchgear, such as KYN-12, JYN-12, GFC-12, etc. The panel applies to 3.6~12kV 3 phase AC 50Hz network for receiving and distributing power energy and also for control, monitor and protection. It accords with standard of IEC62271-200, IEC60694, GB3906.
Working condition:
relative humidty: daily average value < 95%, monthly average value <90%
No explosion, serious pollution, chemica erosion, excessive vibration
earthquick intensity no over 8 degree
Note: Due to continuous product improvement, the dimensions provided in this sample are for reference only. If necessary, our company can design and produce according to user requirements. Please contact the company in time.
