KTH106-3Z type mine intrinsically safe automatic telephone 
 Intrinsically safe telephone automatic telephone automatic telephone 
 KTH106-3Z type mine automatic telephone is intrinsically safe according to Q/HX001-2007 standard production, and its anti-static flame retardant ABS plastic enclosure used injection molding and rugged, the use of modern integrated circuit design from the new circuit The explosion-proof communications products. Hereinafter referred to as "telephone." 
 HDK-based phone calls through the couplers and switches, scheduling PBX infrastructure, composed of intrinsic safety explosion-proof communications system. 
 Telephone to GB3836.1-2000 "Electrical apparatus for explosive gas atmospheres: General requirements", GB3836.4-2000 "Electrical apparatus for explosive gas atmospheres: intrinsic safety" i "" and "MT/T289-1992 intrinsically safe coal mine type of power supply, automatic telephone General "part of the terms of the basis for the design, explosion-proof grade: Exib Ⅰ protection class: IP54. With a waterproof and dustproof function. 
 Telephone is mainly used in explosive gas but not enough to destroy metal and insulation of the corrosive gas and steam environment.
