Specifications

intrinsically safe ,with certificate, coal mine used ,best quality

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”.
