KYN28A-24 armoured withdraw out metal-enclosed switchgear
Product Description
General
KYN28A-24 armoured withdraw out metal-enclosed switchgear(called the switchgear hereafter) is suitable for the voltage system of indoor three-phase 50/60Hz, rated voltage 24KV, and it is mainly used in the power plant, the substation, the industrial enterprises and high-rise buildings. It is used for receiving & distributing the electric energy, and controlling, protecting and monitoring the electric circuit.
KYN28A-24 switchgear has all kinds of functions preventing misoperation, including preventing moving handcart carrying load, closing the breaker when the earthing switch is located in closed position, mistakenly closing the earthing switch when charged, mistakenly bringing into the charged compartment, etc. KYN28A-24 switchgear equips VN2 or VS1 series builtin type high voltage AC vacuum circuit breaker and embedded pole vacuum switch with superior performance. The secondary circuit of switchgear equips the advanced reliable control protection components. The busbar adopts the thermal shrinkage insulating materials or takes the insulation measures of epoxy coating ,and optimizes the electrode shape. The structure of cabinet is compact. KYN28A-24 switchgear is the electrical distribution equipment with the advantages of advanced technology, stable performance, rational construction, convenience of use, safe and reliable.
