Introduction
Explosion-proof intercom phone are widely used in workplaces where explosive gases are present. They are quite different from civilian phone and conventional ones in the presence of explosions.
Explosion-proof intercom phone must be used in environments with explosive gases. Otherwise, it will cause a fire and explosion. Explosion-proof intercom phone do not refer to intercom phone that can resist explosions by themselves, it refers to its ability to operate in an environment with explosive gases.
We know that intercom phone transmit signals through electromagnetic waves
and the transmission of electromagnetic waves relies on electric fields and the continuous conversion of the magnetic field makes it easy to generate electric sparks during this conversion process. Explosion-proof intercom phone, due to their specially treated circuits, can be converted during the process，all the places where sparks could be produced have been shielded.
Explosion-proof intercom phone must also use explosion-proof batteries that are compatible with them. Gas stations, oil depots, oil fields, petrochemicals, petrochemical coal mines, mines, natural gas gasification，flour processing plants, flax processing plants, coal processing plants, fire protection, and industries with large amounts of dust require the use of explosion-proof intercom phone.
