China Wholesale MJ Terminal block Manufacturer – KYN28-12KV Removable AC Metal-clad Enclosed Switchgear – Timetric Detail:

General

KYN28-12KV removable AC metal-clad switchgear (short for switchgear as below) is a new product designed and developed by our company.It is based on the introduction of advanced foreign design and manufacturing technology. Applied to 3.6~12KV, 3-phase AC50Hz network, the panel is used for the reception and distribution of power energy and the system’s control, monitor and protection. It can be arranged for single busbar, single busbar sectionalized system and double busbar. The panel meets IEC298″AC Metal Enclosed Switch and Control Equipment above lKV and below 52KV”,IEC 694 “Standard Common Clauses for High Voltage Switchgear” DIN.VDE”AC Switchgear at Rated Voltage above lKV”, GB3906 “3~35KV AV Metal Enclosed Switchgear”and so on. It has perfect and reliable prevention against misoperation.

Working condition

Products feature

● This product is applicable for our own made GPVN-12KVembedded or insulating sleeve vacuum circuit breaker or ABB’s VD4 vacuum circuit breaker
● We produce and configure GPVC vacuum contactor-fuse combination or ABB company’s VC vacuum contactors,which can be composed of F-C loop cubicle, to meet electrity system of power plants and.
The cabinet adopts double bending bending process and excellent aluminum-zinc steel plate produced by precision CNC machining equipment, which improve itsrength.
● The door surface adopts epoxyresin electrostati powder spray proess,wih resistance of corrosion,oxidation and impact and strong adhesion. OThe cabinet with enclosed structure is fully armored and the function units are completely separated.When the door is closed, it can achieve the
operation of circuit breaker and earthing switch.
● Precision screw drive mechanismensures the chassis with good interchangeabiliy.
● The perfect primary plan meets the various needs of users and enables double chassis plan.
● Fast grounding switch for earthing and short circuits achieves electric ( Motorized ) operation.
● Simple and effective”Five Protection”interlocking device can reliably prevent misuse and ensure operator’ssafety.
● It is arc-proof type. There are pressure relief device on the top bus compartment, vacuum circuit breaker compartment and cable terminal compariment.
● Cable compartment has enough space so it can be easy to connect several cab;es and ensure the right installation height of the cable plug.
● It has strict protection rating (IP40) to effecively prevent foreign matter or pest invasion.
● The security monitoring device of the optional secondary system has a self-diagnostic function and computer with data communication and intelligent .integration, to achieve remote control, telemetry, viewing and adjustment.
● It meets GB3906, GB/T022,DL404 and IEC6227-I standard,and passes a comprehensive test and plateau test (3000m).
● It passes electromagnetic compatibility tests in the high voltage equipment test laboratory.
