Flameproof type “d”
Explosion-proof principle：
An enclosure of electrical equipment that can withstand the internal explosion of a flammable mixture that has entered the enclosure without damage, and will not ignite an external explosive atmosphere formed by the same one or more gases or vapors through any bonding surface or structural hole on the enclosure.
Application examples:
Explosion-proof circuit breakers, switches, lights, starters, buttons, operating columns, distribution boxes, motors.
Increased safety “e”
Explosion-proof principle：
It is a kind of electrical equipment that takes some additional measures to improve the safety of electrical equipment that does not produce arcs and sparks under normal operating conditions, to prevent the possible occurrence of dangerous temperatures, arcs and sparks in its internal and external components.
Application examples:
Explosion-proof junction box, junction box, threading box, transition box, flexible tube, lamp, motor.
Positive pressure type “p”
Explosion-proof principle：
It is an electrical equipment that achieves safety by keeping the pressure of the inner protective gas higher than the pressure of the surrounding explosive atmosphere.
Application examples:
Explosion-proof analysis cabins, large electric motors, power distribution, instrumentation controllers.
Intrinsically safe “i”
Explosion-proof principle：
Electrical equipment that can not ignite the specified explosive gas or vapor under the specified test conditions, the electric spark and the thermal effect generated by the circuit inside the equipment under the specified test conditions, normal operation or specified fault state.
Application examples:
Explosion-proof communication equipment, sensors, regulators, measurement and control equipment.
Encapsulation type “m”
Explosion-proof principle：
Encapsulating arcs, sparks or high temperature parts that may ignite explosive mixtures so that they cannot ignite surrounding explosive gas mixtures.
Application examples:
Explosion-proof transformers, resistors.
