 KYN28-12 Removable AC Metal-clad Switchgear

KYN28-12 removable AC metal-clad switchgear (short for panel as below) is  a new prod uct, designed and developed by HEAG Group, based on the  introduction of advanced foreign design and manufacturing technology. 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 can be arranged for single busbar, single busbar sectionlizing  system or double busbar. It accords with IEC62271-200 AC Metal Enclosed  Switch and Control Equipment above 1kV and below 52kV IEC60694 Standard  Common Clauses for HV Switchgear, DIN. VDE AC Switchgear at Rated  Voltage Above 1kV, GB3906 3~35kV AC Metal Enclosed Switchgear and  so on. It has perfect and reliable prevention function against misoperation.

1. Ambient temperature:  -10 ~40 ; daily average  35 ;  
2. Altitude:  1000m;  
3. Relative humidity: daily average  95%, monthly average  90%;  
4. Earthquake intensity:  8 degree;  
5. Applicable occasions should be free from inflammables, explosives, corrosives and severe vibration.

The enclosure is made of aluminium-zinc plated steel sheet by CNC machine, high precise dimension, short production  cycle, excellent mechanical strength and nice appearance. The busbar compartment, VCB handc art compartment, cable  compartment and relay compartment are separated by metal sheet. Flexible operation for handcart movement, clear position  instruction, the earthing switch allow to making short circuit current and creditable mechanical interlock. It fit with many kinds of  handcart circuit breaker such as VD4, VS1 and VHY1-12 etc, and also select FK(R)N32-12 fixed load breaker switch or VC  series vacuum contactor. The panel adopts air insulated, the door of circuit breaker have the function of anti- explosion, tested by  internal electric arcing fault, without any welding contacts on the panel, mechanical and electrical locking design, the product  conforms to GB 3906, GB/T11022,IEC 62271-200,DL/T404 standards , and passed domestic and Netherlandish KEMA test.
