FLP Intelligent High Voltage Switchgear For Phase Failure , 400A 1140V

Description:

KJZ-1500/1140Z flame-proof and intrinsically safe type intelligent vacuum switchgear is suitable for use in underground mines containing methane mixture gas and prone to dust explosion. On power supply line of 50Hz and1140V it controls start/stop, sequential control or dual speed switching of equipment, such as, shearer, AFC, stage loader, crusher, emulsion pump, spray pump, etc, and provides protection of electric motors and power supply lines. The switchgear is provided with auxiliary power supplies of 127V and 220V for external illumination and controlling systems.

Competitive Advantage:

Digital signal processing, CAN bus, self-adaptive detection, network interface, Chinese (English) character LCD, fault detection, rapid plug-in drive unit, incoming & outgoing cables connected by cable couplers.
