Mine explosion-proof and intrinsically safe communication sound and light signal specs specifications

KTZ127 mine explosion-proof and intrinsically safe communication sound and light signal device is mainly used in coal mines where coal dust and explosive gas are contained. It is suitable for the use of coal mine inclined lane lifting, belt transportation, etc. It can also be used as a direct telephone for the winch house and the wellhead. Sound and light signals are realized by mine moisture-proof speakers and high-brightness light-emitting diodes.

Characteristics of mine explosion-proof and intrinsically safe communication sound and light signal

The product integrates the dot button, explosion-proof lamp, explosion-proof electric bell and three-way junction box. The explosion-proof wiring chamber has a dot button and three outlet ports, which replace the dot button and the three-way junction box, with high-brightness LEDs and The mine moisture-proof speaker replaces the explosion-proof lamp and the explosion-proof bell. Carrier intercom communication is realized through power connection.

The wiring is simple, easy to maintain, easy to use, the communication adopts the frequency modulation power carrier, strong anti-interference ability, long transmission distance, good communication effect, and the product movement adopts epoxy packaging, moisture proof, shockproof and long service life.
