Abstract
The invention discloses an explosion proof type mine cable, consisting of two kinds of conductor cable cores, two drainage wires and five protection layers. The two kinds of conductor cable cores respectively are four groups of tin-plated annealing aluminum alloy conductor cable cores and four groups of silver-plated nickel conductor cable cores; the drainage wires are zinc-plated aluminum alloy drainage wires; the five protection layers sequentially include a silver-plated aluminum alloy wire shielding layer, a fluorinated ethylene propylene insulating layer, a silver-plated nickel strip armor layer, a polyvinyl chloride insulating layer and a nickel plastic copper strip armored polyolefin sheath layer from inside to outside; the silver-plated aluminum alloy wire shielding layer is set to be the central layer of the cable. The cable has the characteristics of being excellent in explosion proof performance, strong in oxidation resistance and ageing resistance, meanwhile is good in drainage effect, and can be widely applied to the fields of mines, petroleum and chemical engineering.
Description
Technical field
The invention belongs to field of cables, particularly relate to a kind of explosion-proof type Coal Electricity cable.
Background technology
Cable and wire is the medium of transmission of electric energy, cable is widely used in every field, relate to people's lives, industrial production various aspects, the quality requirement of each field to cable differs, and some key areas are high especially to the quality requirement of cable, not so cannot satisfy the demand, and may make troubles to work, in the middle of field, colliery, cable is not easy frequent replacing, and the life-span of cable will be grown.
Summary of the invention
In order to increase the practicality of prior art, the object of this invention is to provide a kind of resistance to ag(e)ing strong, resistance to oxidation, drainage effect is good, long-lived explosion-proof type Coal Electricity cable.
The present invention takes following technical scheme to realize: a kind of explosion-proof type Coal Electricity cable, it is by two kinds of conductor thread cores, two drainage threads and five layers of protective layer composition, five layers of protective layer are followed successively by silver coated aluminum B alloy wire screen from inside to outside, perfluoroethylene-propylene insulating barrier, silver-plated nickel strap armour, polyvinyl chloride insulation layer, nickel moulds copper strips armouring polyolefin sheath layer and copper-plastic-aluminium band pe sheath layer, described silver coated aluminum B alloy wire screen is set to the central core of cable, two kinds of conductor thread cores are respectively zinc-plated annealed Al-alloy conductor thread core and silver-plated nickel conductor thread core, zinc-plated annealed Al-alloy conductor thread core is set to four groups, often organize zinc-plated annealed Al-alloy conductor thread core inside and be extruded with 25 zinc-plated annealed Al-alloy conductors, four groups of zinc-plated annealed Al-alloy conductor thread cores are evenly extruded between silver coated aluminum B alloy wire screen and perfluoroethylene-propylene insulating barrier, described silver-plated nickel conductor thread core is provided with four groups, often organize silver-plated nickel conductor thread core inside and be extruded with 6 silver-plated nickel conductors, four groups of silver-plated nickel conductor thread cores are evenly extruded in perfluoroethylene-propylene insulating barrier, between silver-plated nickel strap armour and polyvinyl chloride insulation layer, drainage thread is zinc-aluminium-alloy drainage thread, be provided with four.
Between the silver coated aluminum B alloy wire screen that four zinc-aluminium-alloy drainage threads symmetry is extruded in cable inside and perfluoroethylene-propylene insulating barrier.
The present invention has following beneficial effect in sum: it is excellent that this kind of cable has explosion-proof performance, anti-oxidant strong, ageing-resistant feature, and drainage effect is good simultaneously, can be widely used in the fields such as colliery, oil and chemical industry.
