Introduction
Explosion-proof telephones are used in flammable and explosive places such as power plants and chemical plants. They are equipped with couplers and are also called coupler explosion-proof telephones. They are terminal equipment of explosion-proof communication systems and have the basic functions of ordinary telephones. Explosion-proof telephones can be used by directly connecting to the 24~60 volt local telephone network automatic telephone exchange and user small exchange (or dispatch machine).
The explosion-proof shell of the explosion-proof telephone is cast with aluminum alloy
and the surface is electrostatically sprayed with plastic, which has good impact resistance and protection performance. The keypad of the explosion-proof telephone is made of stainless steel, the handle is an outdoor public telephone handle, and the handle rope is an outdoor public telephone metal sheath cable rope. The circuit components are purchased and produced according to outdoor standards, and the circuit is strictly explosion-proof and protective. The explosion-proof telephone can use an anti-noise handle (also known as an explosion-proof anti-noise telephone) to make the phone clearer in a high-noise environment.
Installation method: wall-mounted screw fastening. The wiring is connected to the user line of the telephone exchange with a two-core cable with an outer diameter less than 8mm. The cross-sectional area of the core wire is ≥0.5mm2, and the line inlet is sealed with a 1/2G” sealing nut.
