Product Introduction
KYN28-12 metal-clad withdrawable switchgear is suitable for 3-phase AC 50Hz/3.6～12kV single busbar and single busbar section system. Apply to distribute electricity power and implement system control, protection supervision monitoring. The switchgear comply with the standards IEC62271, GB3906, DL404.
Operating Conditions
1. Ambient temperature: max. to +40℃min.to-10℃.
2. Altitude: 1000m(max).
3. Relative humidity: daily average less than 95%, monthly less than 90%.
4. Shock of earthquake: less than 8 magnitude.
5. This product should not be used under conditions of fire, explosion, earthquake and chemical corrosion environments.
Characteristic
1. Metal-cald and partition completely, efectively pre- vent faults spreading.
2. The low voltage section is completely separated from the high voltage sections.
3. Enclosure p rotection deg ree is IP4X, protect against electric shock and ing ress of solid foreign bodies.
4. Simple but effective interlocking prevents malopera- tion.
5. Space is provided for multiple cable connections. Installation and maintenance is convenient.
6. Withd rawble part of the same design are mutually in- terchangeable, an exchange of VCB is very simple.
