Abstract
The utility model discloses a low temperature resistant, flame-retardant and light-duty control comprehensive explosion-proof cable which comprises multiple insulating pair-twisted shielding sheath cable cores, multiple insulating cable cores and one insulating shielding sheath cable core. The multiple insulating pair-twisted shielding sheath cable cores respectively comprise two first conductors, one second conductor and three third conductors which are twisted. The multiple insulating pair-twisted shielding sheath cable cores, the multiple insulating cable cores and the one insulating shielding sheath cable core are externally provided with an external wrapping layer formed by wrapping polyester film, an external shielding layer formed by weaving tin-coated copper filament, and an external protective sheath formed by extruding polyurethane elastomer in turn. The cable is simple in structure, and has characteristics of being high in strength, great in toughness, low temperature resistant, flame-retardant, thin in insulating layer and light in weight. Explosion-proof grade is grade II so that the cable has a high explosion-proof characteristic. Application temperature ranges from -50 DEG C to 120 DEG C so that operation requirements of electronic devices in more demanding environment are met.
