Kyn28 Drawout Type Indoor Switchgear

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.

The newly introduced and developed large current and high breaking switchgear can also be used as a high- voltage generator export.

KYN28-12 indoor metalclad withdrawable switchgear is designed to be complete distribution equipment with three-phase A.C. singe busbar and single busbar section system having a rated voltage of 3.6~12kV and rated frequency of 50Hz.The switchgear is mainly employed in receiving and distribution of power energy from the network as well as starting of large-sized HV motors. In addition, the switchgear is provided with controlling, protection and monitoring functions. The switchgear conforms to IEC 298, GB 3906, DL/T404-91 and other standards. The switchgear itself owns five prevention functions such as prevention of misoperation of circuit breakers, prevention of pushing or pulling truck with load, prevention of closing earth switch under voltage, prevention of supplying power when earth switch is at the earth position and prevention of entering the electrical separation zone by accident. The switchgear selects not only VS1 vacuum circuit breakers but also ABB made VD4 vacuum circuit breaders, thus recogninzed as power distribution equipment with excellent performance.

JSA Exports, a renowned player in the import-export sector, proudly presents a
comprehensive range of high-quality switchgear products. Our meticulously
crafted switchgear solutions are designed to effectively manage and control electrical power systems with utmost precision and reliability.

I. Summarization
KYN28A-24 indoor AC metal armoured pull-out switch cabinet is suitable for three-phase AC 50/60Hz power system, for receiving and distributing power, and for controlling, protecting and testing the circuit. APG epoxy casting and reliable solid insulated bus technology are used in the interior of the product for full insulation design. It has good electric field distribution measures. It is a miniaturized switchgear with advanced technology, stable performance, reasonable structure, convenient use, safety and reliability.
â?¡.CHARACTERISTICS of China High Voltage Switch Cabinet
1. Bus bar adopts thermal shrinkable insulating material or epoxy coated insulation method to optimize the shape of the electrode, make the cabinet structure compact and reduce the occupied area.
2. The High Voltage Switch Cabinet body is made of high-quality cold-bonded steel plate and imported aluminium-zinc coated sheet metal, which are processed by NC sheet metal and connected by high-strength bolts, nuts and rivet nuts.
3. The switchgear equipment has other primary schemes such as cable in-out line, overhead in-out line, bus connection, isolation, voltage transformer, lightning arrester and so on.
4. Insulation boards are installed in bus cabinet, handcart cabinet and cable cabinet, which greatly improves the insulation level.
5. The interlock between main LOAD SWITCH, handcart, ground knife switch and cabinet door adopts mandatory mechanical door lock mode to meet the "five-proof" function.
6. Friendly man-machine interface makes switchgear operation programmable and formulaic, and the operator can see it at a glance.
7. The main wiring scheme can reach more than 160 kinds, and has strong structural adaptability, which can meet the needs of different users.

XGN2 Type Modular High Voltage Switchgear,High Voltage Switchgear,High and Low Voltage Switchgears
XGN2 type modular high-voltage switchgear cabinet is applied to receive and distribute the electrical energy in three-phase AC power system with rated voltage 3, 6, 10KV and rated frequency 50HZ
Product Description
XGN2 type modular high-voltage switchgear cabinet is applied to receive and distribute the electrical energy in three-phase AC power system with rated voltage 3, 6, 10KV and rated frequency 50HZ, especially for the frequently operated occasion. Its busbar system is a single busbar (which can derive the single busbar with bypass and double busbar structure). The switchgear cabinet is in line with the requirements of the National Standards GB3906 3-35KV AC Metal-enclosed Switchgear and the international Standard IEC298, also there are proposed "five anti" interlocking functions such as anti-breaking and closing by mistaken for circuit breaker, anti-breaking and closing disconnector switch with load, anti-breaking and closing grounding wire/switch with load, anti closing circuit breaker/disconnector switch with grounding wire/switch, anti entering charged interval by mistaken.

Product Features
The main switch of the switchgear applies ZN28A-10 series vacuum circuit breakers, equipped with CD117 series of electromagnetic operating mechanism and CT19 series of spring operating mechanism. Using GN-30 rotary isolating switch.
