Introduction of HDB-1 explosion - proof telephone
This phone is of intrinsically safe type, which has the functions of common telephone and all-electronic contactless induction. The circuit adopts special technology, strong vibration bell, low power consumption and high explosion-proof level. The telephone is matched with the associated equipment HOB-1 explosion-proof coupler and connected with the switch to form an explosion-proof communication system.
Mainly used in power plants, chemical and petroleum industries, indoor and outdoor can be used. The telephone set produced by our company has the characteristics of high explosion-proof grade, long service life, easy installation, wide use and loud sound. Hdb-1 type explosion-proof telephone is a new technical product developed by combining foreign advanced technology with China's explosion-proof product standards and the requirements of the majority of users. The outer shell of the machine is made of ABS enhanced engineering plastic injection, and the circuit is made of special technology and measures.
