Abstract

Track traffic 1500V and following DC traction prevent biological power cable of destruction, from the center to outer include insulating layer in the copper conductor outside of copper conductor, crowded package in proper order, around the water blocking layer of package in the insulating layer outside, cup joint the airtight metal covering on the water blocking layer and crowd thermoplasticity or the thermoset restrictive coating that wraps on airtight metal covering, the copper conductor includes that 5 copper cores that splice each other, copper core wind the armor of package and the polyester fiber layer that crowded package thickness outside the copper strips armor is 3mm outward. Simple structure improves production efficiency, practices thrift raw and other materials, reduces the energy consumption.

Description

Track traffic 1500V and the anti-biological destruction power cable of following DC traction
Technical field
The utility model relates to power cable for rail transit, particularly relates to track traffic 1500V and the anti-biological destruction power cable of following DC traction.
Background technology
The technical requirement of existing track traffic 1500V and following DC traction power cable performs GB/T28429-2012: track traffic 1500V and following DC traction power cable and annex, for the electric power transfer of orbit traffic direct current trailer system, the protection against rodents of existing track traffic 1500V and following DC traction power cable (hereinafter referred to as cable), termite-proof method add chemical addition agent in sheath.Sheath in use because of external force or natural aging cause break time, the protection against rodents of cable, termite-resisting function actual effect at once.Be subject to mouse, ant infringement cable can cause insulation breakdown, cause the fault of transmission system.
Summary of the invention
The utility model is for the deficiencies in the prior art, and provide a kind of structure simple, cost of manufacture is low, can effectively the track traffic 1500V of protection against rodents and termite and the anti-biological destruction power cable of following DC traction.
For realizing the utility model object, provide following technical scheme: track traffic 1500V and the anti-biological destruction power cable of following DC traction, it is characterized in that comprising successively copper conductor, the insulating barrier extruded outside copper conductor, wrapped water blocking layer outside insulating barrier from center to skin, be socketed on closed metal cover on water blocking layer and the thermoplasticity extruded on closed metal cover or thermosetting restrictive coating, described copper conductor comprise 5 mutually hinge joint copper cores, the outer wrapped armour of copper core and extrude in the outer thickness of armour be the layer of polyester fiber of 3mm.
As preferably, insulating barrier is crosslinked polyethylene or ethylene-propylene rubber or hard ethylene-propylene rubber.
As preferably, water blocking layer is wrapped non-conductive waterstop outside insulating barrier.
As preferably, armour is woven by many one metal wires or concentric stranding wiry forms or put up wrapped composition by one or more metal tape spiral.
As preferably, closed metal cover for thickness be the Resisting fractre metallic sheath of 1.5mm.
The utility model beneficial effect: the utility model structure is simple, enhance productivity, save material, reduce energy consumption, when breakdown fault appears in insulation, because the breakdown channel of conductor, insulating barrier, metallic sheath constitute galvanic circle, thus by existing cable fault locator, can failure judgement point position immediately, discharge fault rapidly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment 1: track traffic 1500V and the anti-biological destruction power cable of following DC traction, from center to skin, comprise copper conductor 1 successively, the insulating barrier 2 extruded outside copper conductor 1, wrapped water blocking layer 3 outside insulating barrier 2, be socketed on closed metal cover 4 on water blocking layer 3 and the thermoplasticity extruded on closed metal cover 4 or thermosetting restrictive coating 5, described copper conductor 1 comprises 5 the copper core 1.1. of hinge joint, the outer wrapped armours 1.2 of copper core 1.1 and to extrude in the outer thickness of armour 1.2 be the layer of polyester fiber 1.3 of 3mm mutually.Insulating barrier 2 is crosslinked polyethylene or ethylene-propylene rubber or hard ethylene-propylene rubber.Water blocking layer 3 is wrapped non-conductive waterstop outside insulating barrier 2.Armour 1.2 is woven by many one metal wires or concentric stranding wiry forms or put up wrapped composition by one or more metal tape spiral.Closed metal cover 4 for thickness be the Resisting fractre metallic sheath of 1.5mm.Copper wicking surface is provided with zinc coat.
