Oil-filled part of the entire device or equipment within the oil invasion protective solution I l, so they can not point above the fuel surface or shell explosion outside atmosphere. Filling sand filling sand or other specified characteristics of the powder material in the shell, so that under the conditions of use prescribed proof floodlight specifications, arcs or high temperatures generated by the shell can not ignite a surrounding explosive gas explosion-proof equipment such airtight h Type hermetic shell. Ie explosive gas mixtures in the environment can not invade the device housing. Airtight shell with melted, extruded or adhesive sealing method, which is mostly non-removable enclosure to ensure permanent tightness. Type of electrical equipment to protect the environment. LED lighting is an explosion-proof performance of a class of lighting, with such signs Ex. Explosion-proof floodlight lamps sealing performance, further protective measures in the structure, and so proof floodlight suppliers, the state has certain requirements for explosion-proof lighting. Rather than proof lamps are not above requirements. 1, explosion proof lighting category, level and temperature class see national standards. 2, divided according to the type of protection flameproof, increased safety, positive pressure, dust-proof and non-sparking type 5 main types, you can also by other types of protection and a combination of these various types of protection or complex shape and special type. 3, according to protection against electric shock type can be divided into Ⅰ, Ⅱ, Ⅲ category. Electric shock protection is to prevent explosion lamp housing accessible live parts, the conductor of electric shock or a different potential human touch spark and ignite an explosive mixture.
