Details
The intrinsically safe network switch for mines is a key component of the underground part of the mine wireless communication system, and is used in conjunction with the dispatching host, communication substation, mobile phone, identification card, card reader substation and other equipment to realize wireless communication, personnel positioning and other functions. The switch can also communicate with the dispatching host, transmit the collected signals to the ground dispatching station, and can also execute various remote control instructions issued by the dispatching station.
The switch is an intrinsically safe product for mines, which can be used in coal mines with explosive mixtures of methane and coal dust, but without significant vibration and impact, and without corrosive gases that damage insulation.
Explosion-proof type: Intrinsically safe for mines, the explosion-proof mark is ExibI Mb.
