Indoor Metal Clad Medium Voltage Switchgear For Power Transmission / Distribution

MV medium voltage KYN28-12 metal-clad switchgear

KYN28 indoor metal-clad withdrawable switchgear(hereinafter short as switchgear) which is for distributing and accepting 3-phase AC electricity (3-12 kV, 50 Hz) distribution system, single-bus and single-bus sectionalized system. It is universally applied within power transmission of middle/small generators in power plants; power receiving, transmission for substations in power distribution and power system of factories, mines and enterprises, and starting of large high-voltage motor, etc. The switchgear compliant with IEC298,GB3906-9. Besides, it also can control, protect and monitor the circuit.
Simple and effective lock system to prevent misuse. Reliable FIVE-PREVENTION interlock can effectively prevent from mal-operation and entrance into energized compartments.
1, Prevent pushing and pulling circuit breaker handcart with loads;

2, Prevent circuit breakers from mal-operation;

3, Prevent the circuit breaker from closing and connecting when earth switch in live condition;

4, Prevent straying into electrified compartment;

5, prevent connecting error of grounding switch while live.
Perfect Removable part of the switchgear can mount with vacuum circuit breaker and vacuum contactors components, etc.
The cabinet can debugged or maintained from front or behind, when adopt front side for debugged,
can be installed against a wall or back-to-back be a double arrangement, more flexible for installation and reducing floor space.
