Medium Voltage 12KV Metal-Clad Enclosed Switchgear
Model: KYN28-12
Voltage: 12Kv 24Kv
Product Overview :
KYN28-12 indoor drawer style metal-clad electrical switchgear
1. General
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.
Fully type-tested
The switchgear has undergone all the tests required by the international (IEC) Standards. Each
switchgear unit is subjected to routine tests in the factory before delivery. These tests are
intended to provide a functional check of the switchgear based on the specific characteristics of
each installation.
IEC type tests
? Short-time and peak withstand current
? Temperature rise
? Internal arc capability
? Dielectric test
? Making and breaking capacity of circuit-breaker
? Earthing switch making capacity (top application)
? Mechanical operations of circuit-breaker and line
disconnector
? IP degree and impact test

Structural characteristics
1. It has perfect mechanical and electrical double locking and anti error operation function.
2. The cabinet can be flexibly equipped with VS1, VYG, VD4, VN2 and other vacuum circuit
breakers.
3. The roof part adopts ventilation design, that is, it can meet the need of dust prevention
and no need to consider the problem of pressure relief.
4. Cabinet use: single axis, double shaft and so on, to meet different requirements.
5. Using Aluminum-zinc composite flanging process, application of flat screw installation,
flexible use, convenient, simple and practical, good performance.
6. KYN28-24 in the high voltage electrical equipment quality supervision and inspection center
through the full tank type experiment, its design and manufacture fully meet the requirements of
GB, DC, IEC standards.
