KYN28A-24 Metal-clad movable type metal-enclosed switchgear (hereinafter called switchgear), which is suitable for indoor three-phase 50Hz and rated voltage 24KV electric system, mainly applied in power factory, substation, industrial and mining enterprises and high-rise for receiving and distributing power energy and controlling, protecting and supervising electric circuit.
KYN28-12 metal armored moving switchgear(indoor)
Usage:
KYN28-12 metal amored moving switch equipment is mainly applied to distribution system: AC 50Hz with rated working voltage 3-10KV, rated working current up to 3150A. It takes actions as receving&feeding the electricity for power plantsubstation, facotry, high bulding etc. And starting the large electromotor.
Feature:
1: Excellent and reliable performance, long service life
2: Well controllling&protection of loop.
3: Protection level: IP40
4: Each switch cabinet consist of several functional unit, which isolated by steel sheet. Aslo there is strict isolation between cabinets. So that can avoid expansion of accident effectively.
Main switch (Vacuum circuit break) is withdrawable, you can replace it when there is a emergency fault happened.
5: This cabinet possesses perfect "five-prevention" function
6: The products conform to GB3906-2006, DL404 and IEC404 standard
We can produce according to your design and request
The enclosure is completely assembled from aluminized and galvanized steel plate, which are machined and bent by machine tool and then bolted.
It has high mechanical strength and its neatness and beauty is ensured.
The switchboard door is sprayed with plastic, also has strong capacity of impact resistance and corrosion protection.
The protection grade of the enclosure is of IP4X.
The primary switch may be provided with VD4 vacuum circuit breaker and C3 series of fixed type load switch from ABB, various domestic vacuum circuit breakers (such as VS1, VH1, VK, ZN28) may also be provided in lieu of the same foreign products.
