Enclosure of Metal-Clad Removable Switchgear (KYN28A-24)

Introduction
Our enclosure is made of Al.-Zinc plated steel sheet, designed for medium voltage switchgear given type is KYN28A and made up by advanced technology in full range of technical specifications. The air insulated switchgears' features are stable, high reliable performance and easy of use. It is mainly used as a monitor and protector in primary substation power distribution systems and large-scale high voltage motors of electric power plant, industries and mining enterprises.The KYN28A switchgear consists of cabinets and handcart. The enclosure is divided into several functional compartments separated by metal partitions.Busbar room;Circuit breaker room;Cable room;Low voltage instrument room.
Different functions can categorize the handcart into circuit breaker handcart, voltage transformer handcart, metering handcart, isolation handcart, arrester handcart, fuse handcart, etc. Handcart of the same specification are freely interchangeable with each other.Technical parametersRated voltageKV7.2122440.5Rated frequencyHz50/60Rated 1min. power frequency withstand voltageKV32426595Rated lightning impulse

FeaturesThe MV. Switchgear can be equipped with circuit breakers named as VD4/ABB, EV128/Schneider, 3AE/Siemens, VS1/Canin.Unique innovation concave-convex style with blue eliminates visual fatigue.The switchgear enclosure used high quality 2mm thick aluminum-zinc plated steel sheet, processed by CNC machine. The entire cabinet is excellent in precision and resistance to corrosion and oxidation.Handcart and cabinet coordinate well with safe, reliable and flexible mechanical interlocking mechanism.Mechanical and electrical operations are interlocked with all doors closed.Switch cabinet can be mounted against wall. Maintenance is allowed to be carried out in front of the cabinet. Space occupation is reduced quietly.Cable room has plenty of space for connecting 6 cables.Operation of the switchgear can be observed through an inspection window in front door of breaker room.
Multifunctional modular designIncoming cabinet can be equipped with vacuum breaker;Outgoing cabinet can be equipped with vacuum breaker;Busbar cabinet can be equipped with vacuum breaker;Isolation cabinet can be equipped with isolating handcart;Busbar lifting cabinet can be with and without measurement;Motor outgoing cabinet can be with vacuum contactor;PT cabinet can be with PT handcart with vacuum contactor;Capacitor cabinet can be with fuse handcart, surge arrester handcart;The switchgear can be designed for different purposes according to customer's requirements.
