What Are The Explosion-proof Types Of Explosion-proof Phones

1. Flameproof enclosure type "d"

The explosion-proof safety performance of electrical equipment with flameproof enclosures is mainly guaranteed by the "flameproof enclosure". The "flameproof enclosure" allows the explosive gas mixture entering the interior to ignite and explode within the enclosure, but it does not permit the explosion to spread out of the enclosure and ignite the surrounding explosive gas mixture.

2. Increased Safety type "e

The explosion-proof safety performance of increased safety electrical equipment mainly involves taking some structural measures and safety requirements for the electrical equipment to further enhance their safety and reliability, thereby making it impossible for them to become ignition sources of flammable gases.

3. Intrinsically safe "i"

The explosion-proof safety performance of intrinsically safe electrical equipment is mainly achieved by limiting the energy of the circuit to prevent explosion. In such electrical equipment, even if electrical discharges and thermal effects caused by faults such as short circuits, open circuits, and insulation breakdowns occur in the circuit, they cannot ignite the explosive gas mixture.
