KTH186 dual circuit mining explosion-proof telephone

     The KTH186 intrinsically safe mining telephone is a high-performance, high reliability explosion-proof communication terminal developed and produced using the latest electronic technology and digital noise reduction processing technology, based on our company's long-term experience in industrial production scheduling communication system research and development. It can be connected to various existing switches or scheduling hosts to form an explosion-proof communication system.

The KTH186 intrinsically safe mining telephone has explosion-proof performance and a high protection level (wind and rain resistance, corrosion resistance, anti knock), with a protection level of IP65. It is widely used in harsh working environments such as outdoor, high temperature, high humidity, heavy pollution, and high noise, such as steel rolling workshops, power plants, water power plants, coal preparation plants, coal mines, metal and non-metal mines, ports, etc.

Product features:

● It has dual circuit protection function and is used in conjunction with the KTJ132 dispatch host. The cables are routed down from the main and auxiliary shafts and then connected to the KTH186 telephone. If any line breaks or experiences a short circuit fault, it does not affect the normal use of the telephone and can report the line fault to the system, indicating that the line is short circuited or open circuited, which is convenient for troubleshooting.

The phone casing is made of polyester material molded, waterproof, dustproof, and corrosion-resistant, with a protection level of IP65, suitable for various harsh environments.

Wall mounted installation, using a magnetic fork spring switch structure, with no movable parts on the phone.

The keyboard is fully sealed with luminous light touch buttons, and is equipped with emergency call, hang up, and redial keys.

The front of the phone is equipped with a ringing indicator light, making it easy to identify incoming calls in dim environments.
