KTH 18 Flame Proof Manufacturer Explosion Proof Intrinsically Safe Automatic mining telephone
1.Aplication
KTH106-Z mining explosion-proof intrinsically safe automatic telephone is produced according to the standard Q/HX001-2007.
It is a telephone combined with impulse and double audio frequency, configured with KTA104 mining telephone coupler and dispatching desk whose outputting signal meets requirement or switch, to achieve safe communication internet of coal mine. It can be used in the places around explosive gas and the Ex-mark is “ExibI”.
2.Main Features
1)the material of the telephone is Aluminum with beautiful appearance and the mechanical strength high.
2)adopt the new type keyboard.
3) adopting international general integral circuit, with merits of signal accurate , voice clear, work stable.
4)with functions of double audio frequency and impulse signal sending.
5)with features of explosion-proof, anti-moisture, volume small, weight light, solidity, durability, maintenance convenient.
