A tri-proof explosion-proof lamp integrates water resistance, dust resistance, corrosion resistance, and explosion-proof capability. It uses an explosion-proof enclosure and meets Ex explosion-proof standards to prevent internal electric sparks from igniting external explosive mixtures, while having a high IP rating and passing salt spray tests, so it can be used in humid, dusty, corrosive environments with explosion risks. Its housing is mostly aluminum alloy, the light cover is tempered glass, common power is 20W to 90W, protection rating up to IP65 and above, widely used in petrochemical, coal mining, port and terminal, and other places.
