Explosion proof lighting distribution box is a special electrical equipment designed for flammable and explosive hazardous areas, mainly used for distributing, controlling, and protecting lighting circuits. Its design complies with explosion-proof standards and can effectively prevent internal arcs or sparks from igniting hazardous environments such as explosive gases and dust.

Application scenarios

Petrochemical industry: refineries, chemical plants, gas stations, etc.

Underground coal mine: a roadway or working face with high gas concentration.

Dust environment: Explosive dust areas such as grain processing, textile factories, flour mills, etc.

Other hazardous areas: natural gas stations, oil depots, pharmaceutical factories, etc.

Key selection points

Explosion proof level: Select the corresponding explosion-proof mark based on the degree of environmental hazard (such as Ex d IIB T4, Ex tD A21, etc.).

Material: Stainless steel is preferred for corrosive environments, and aluminum alloy is optional for lightweight requirements.

Capacity: Select the number of circuits and current specifications based on the load power (such as 4-circuit, 6-circuit, 63A, 100A, etc.).

Additional features: Whether remote control, overload protection, temperature monitoring, etc. are required.

Installation and maintenance

Installation requirements

It must be carried out by professionals to ensure reliable sealing of cable entry devices (such as explosion-proof gland heads).

Avoid installing in locations with severe vibrations or direct exposure to high temperatures.

Maintenance precautions

Regularly check whether the sealing ring and cable inlet are aging or loose.

Open the cover for maintenance after power outage, and prohibit live operation.
