Abstract
The utility model relates to a high tensile power cable used in a deep well, which is used in a deep well or on a power transmission line with big drop. The high tensile electric power cable comprises an outer sheath in which a conductor provided with an insulating layer is arranged; a wire rope is arranged between the conductor provided with the insulating layer and the outer sheath; a cushioning layer is arranged at the outer surface of the wire rope; and stuffing is arranged among the cushioning layer, the insulating layer and the outer sheath. The high tensile electric power cable can effectively prevent the damage to the cable caused by dead-weight of the cable and the weight of the wire rope and saves material. The utility model replaces the wire armoring layer with the wire rope provided with a cushioning layer, and when aluminum clad steel or copper clad steel is adopted as the conductor, the tensile strength of the cable can be greatly increased, the cable is not easy to rupture, and the wire rope and the insulated wire core can be twisted together, which largely enhances the bonding force between the wire rope and the cable and more importantly enhances the tensile strength of the cable. The cushioning layer at the outer surface of the wire rope is good for combining with the insulated wire core and at the same time prevents the wire rope from piercing and scratching the cable.
Description
Technical field
The utility model relates to a kind of cable that uses in the power transmission lines of deep-well and big fall laying, relate in particular to a kind of deep-well high tensile power cable that uses in the power transmission lines of dark mine.
Background technology
In the big power transmission lines of deep-well and drop, especially in dark mine, need to adopt the cable (as shown in Figure 1) of LWA light wire armoured or thicker wire.The skin of this cable is made up of oversheath (1) and inner sheath (3), between oversheath (1) and inner sheath (3), be provided with steel wire (2), in inner sheath (3), be provided with the conductor (6) that has insulating barrier (5), between conductor that has insulating barrier (5) (6) and inner sheath (3), be provided with filler (4), oversheath (1) is polyvinyl chloride or polyethylene, steel wire (2) uses zinc-plated thicker wire or finer wire, inner sheath (3) uses polyvinyl chloride, filler (4) is polypropylene mesh tearing film or polyvinyl chloride or polyethylene rope, insulating barrier (5) adopts polyvinyl chloride and polyethylene insulation when conduction low pressure, adopt crosslinked polyethylene three-layer co-extruded when the conduction high pressure, conductor (6) adopts aluminium conductor or copper conductor.But because the weight and the steel wire armoured weight of this cable self are very big, easy fracture of cable conductor and whole cable are easily moved downward, cause the accident easily.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of and can prevent effectively because cable deadweight and steel wire weight to the destruction of cable self, can be saved raw-material deep-well high tensile power cable again.
The purpose of this utility model is achieved in that and comprises oversheath, it is characterized in that: in oversheath, be provided with the conductor that has insulating barrier, between conductor that has insulating barrier and oversheath, be provided with steel wire rope, outside at steel wire rope is provided with resilient coating, is provided with filler between resilient coating, insulating barrier and oversheath.
Described conductor adopts aluminium Baogang or copper covered steel or copper conductor.
Described resilient coating is polyvinyl chloride or polyethylene or other high polymer.
Described oversheath uses polyvinyl chloride or polyethylene.
Described insulating barrier adopts polyvinyl chloride and polyethylene insulation when low pressure, adopt crosslinked polyethylene three-layer co-extruded when high pressure.
Described filler is polypropylene mesh tearing film or polyvinyl chloride or polyethylene rope.
Described steel wire rope uses corrosion-resistant finer wire or thicker wire.
The steel wire rope that has resilient coating is in the same place with the insulated wire cores winding stranding that the conductor that has insulating barrier constitutes.
The utility model can effectively prevent because cable deadweight and steel wire weight to the destruction of cable, have been saved raw material again.Replace the wire armoring layer with the steel wire rope that has resilient coating, adopting aluminium Baogang or copper covered steel is conductor.The tension effect of cable self is strengthened greatly, be not easy fracture.Steel wire rope twines stranding with insulated wire cores again and is in the same place, this adhesion that has strengthened steel wire rope and cable again greatly be the more important thing is the tension effect that has strengthened cable simultaneously and since steel wire rope outside have resilient coating help with insulated wire cores in conjunction with having avoided steel wire rope to stab and scratch cable again.
Description of drawings
Fig. 1 is the structural representation of prior art middle-deep well with power cable.
Fig. 2 is the structural representation of deep-well with the high tensile power cable.
Embodiment
As shown in Figure 2, the utility model comprises oversheath 10, in oversheath 10, be provided with the conductor 7 that has insulating barrier 11, between conductor 7 that has insulating barrier 11 and oversheath 10, be provided with steel wire rope 8, be provided with resilient coating 9 in the outside of steel wire rope 8, between resilient coating 9, insulating barrier 11 and oversheath 10, be provided with filler 12.
Described conductor 7 adopts aluminium Baogang or copper covered steel or copper conductor.Resilient coating 9 is polyvinyl chloride or polyethylene or other high polymer.Oversheath 10 uses polyvinyl chloride or polyethylene.Insulating barrier 11 adopts polyvinyl chloride or crosslinked polyetylene insulated when low pressure, adopt crosslinked polyethylene three-layer co-extruded when high pressure.Filler 12 is polypropylene mesh tearing film or polyvinyl chloride or polyethylene rope.Steel wire rope 8 uses corrosion-resistant finer wire or thicker wire.
The utility model is the conductor of cable with aluminium Baogang or copper covered steel or copper conductor, twines the wire armoring layer (as shown in Figure 2) that stranding has replaced the tension effect together with steel wire rope that has resilient coating and insulated wire cores.When employing has the conductor of steel core, the tension effect of cable self is strengthened greatly, be not easy fracture.Steel wire rope twines stranding with insulated wire cores again and is in the same place, this has strengthened the adhesion of steel wire rope and cable again greatly, the more important thing is the tension effect that has strengthened cable simultaneously and since steel wire rope outside have resilient coating help with insulated wire cores in conjunction with having avoided steel wire rope to stab and scratch cable again.
