Abstract
The invention discloses a high-temperature resistant and waterproof coaxial cable, which comprises a coaxial wire core and a protective sheath, wherein the protective sheath coats the outer side of the coaxial wire core; a shielding layer, a waterproof layer and a high-temperature resistant layer are sequentially coated between the coaxial wire core and the protective sheath; the coaxial wire core comprises a center conductor, an aluminum foil armor layer and an outer conductor; the center conductor is formed by stranding 99.99% anaerobic-annealed and nickel-plated superfine soft copper wire bundles; a ground wire core is coated with the outer conductor; the ground wire core is formed by coating the outside of tinned and annealed soft copper wires with an annealed steel wire and twisting and weaving the wires towards the right at 270 degrees; and a drainage wire is coated with the waterproof layer. The cable disclosed by the invention has good conductivity, high temperature resistance, waterproofness, dragging resistance and wire breakage resistance; and the high-temperature resistant layer of the cable can withstand the maximum temperature of 1,000 DEG C, ensures that a circuit is open in a fire, and is mainly applied to an underground roadway.
Description
Technical field
The invention belongs to field of cables, particularly relate to a kind of high temperature resistant waterproof coaxial cable.
Background technology
At present, along with socioeconomic development, cable consumption increases rapidly, also constantly improves the quality requirement of cable.Such as in the exploitation work of coal mine, because underworkings is dark, common cable many employings PVC sheath, resistance to elevated temperatures is inadequate, once cable fire will discharge a large amount of dense smoke and toxic gas, impact rescue.
Only have the multiple requirements of symbol cable, just can better ensure the safe handling of cable.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of high temperature resistant waterproof coaxial cable.
The present invention takes following technical scheme to realize: a kind of high temperature resistant waterproof coaxial cable, the sheath that it comprises coaxial core and is wrapped in outside coaxial core, is also enclosed with screen, watertight composition, high-temperature-resistant layer between described coaxial core and sheath successively; Described coaxial core twists center conductor, aluminium foil armour and outer conductor by the ultra-fine soft copper tow of employing 99.99% anaerobic annealing nickel plating and forms, described outer conductor internal package ground connection core, described ground connection core is that 270 ° of stranded braidings to the right form by zinc-plated annealed copper silk outsourcing annealed wire;
Described watertight composition internal package drainage thread.
Described high-temperature-resistant layer is closely wrapped up by several high temperature resistant alkali-free glass fiber cloth and forming.
Described sheath is rolled by ceramic fireproof silicon rubber and ethylene-propylene rubber to be composited.
The present invention has following beneficial effect in sum: this kind of cable conduction performance is good, high temperature resistant, and water resistance is good, resistance to towing, anti-broken string, wherein, the high-temperature-resistant layer of cable can bear the highest 1000 DEG C, ensures circuit in the case of fire unimpeded, is mainly used in underworkings.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention.
Wherein: 1, coaxial core: 1A, center conductor; 1B, aluminium foil armour; 1C, outer conductor; 2, screen; 3, watertight composition; 4, high-temperature-resistant layer; 5, sheath; 6, ground connection core; 7, drainage thread.
