KYN28-24KV withdrawable switchgear
KYN28-24KV withdrawable switchgear
Detail

KYN□-24 series of indoor withdrawout metal-clad switch cabinet applyto indoor power system of three phase 50/60Hz, rated voltage 24KV. They aremainly used in power plant, substation, industry and mining enterprise andhigh-rise buildings to receive and distribute electric energy and control,protect and monitor the electric circuit. KYN□-24 series of indoor withdrawout metal-clad switch cabinetis of advanced technology, stable performance, reasonable structure, easyoperation, reliable.


Main characteristics and technical parameters

The shell of the switchgear applies the aluminum-zinc alloy coatedsheet plate brought in abroad, processed by CNC machine tool, applies multiplefolding technology. The whole cabinet has the advantage of high accuracy,strong anti-corrosion and anti-oxidation ability. And for the multiple foldingtechnology, the cabinet is much lighter than the other similar cabinet, andstronger mechanical strength. The cabinet applies the assembly structure,connected by pulling rivet and high-strength bolt. The framework of thewithdrawable handcart applies thin steel plate,  processed by CNC machining tool. The handcartis classified as vacuum circuit breaker handcart, voltage transformer handcart,lighting arrester handcart, isolating handcart, measuring handcart, transformerused handcart and fuse handcart. The same specification handcarts can beinterchanged. The main electric components of the switchgear has independentcompartment, that is: circuit breaker handcart chamber, bus chamber, cableroom, relay instrument room and so on. The protection level of all cubicles isover IP2X. The other three compartments have their own pressure release pathwaysexcept the relay instrument room. The mid-set structure greatly increase thecable room space, and thus multiple cable can be paralleled connec KYN□-24 series of indoor withdrawout metal-clad switch cabinet applyto indoor power system of three phase 50/60Hz, rated voltage 24KV.
