Abstract
Track traffic 1500V and fire -retardant power cable of following DC traction, 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 outward and crowd the polyester fiber layer that package thickness outside the armor is 5mm, and the packing has waterproof material between armor and the copper core, and the armor comprises around wrapping many aluminium strip spirals, and water blocking layer crowded package the outward has or not fire -retardant layer of the low cigarette of bittern or takes at a distance from the fire around wrapping the low cigarette of nothing bittern that has non -hyproscopic. Simple structure has good fire -retardantly with waterproof performance and when the puncture trouble appearing, can judge fault point position immediately, the trouble of discharging rapidly when insulating.
Description
Technical field
The utility model relates to power cable for rail transit, particularly relates to track traffic 1500V and following DC traction flame-proof power cable.
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, existing track traffic 1500V and following DC traction power cable (hereinafter referred to as cable) complex structure, fire resistance is poor, haves much room for improvement.
Summary of the invention
The utility model is for the deficiencies in the prior art, provide a kind of structure simple, there is good fire-retardant and water resistance and when breakdown fault appears in insulation, can failure judgement point position, the rapidly out of order track traffic 1500V of row and following DC traction flame-proof power cable immediately.
For realizing the utility model object, provide following technical scheme: track traffic 1500V and following DC traction flame-proof power cable, it is characterized in that comprising copper conductor successively from center to skin, extrude the insulating barrier outside copper conductor, wrapped water blocking layer outside insulating barrier, be extruded with LSOH anti-flaming layer outside water blocking layer or be surrounded with non-hygroscopic low smoke, zero halogen fire insulation band, be socketed on LSOH anti-flaming layer or be surrounded with on non-hygroscopic low smoke, zero halogen fire insulation band closed metal cover and extrude the thermoplasticity or thermosetting restrictive coating that put in closed metal, described copper conductor comprises 5 copper cores mutually linked, the outer wrapped armour of copper core and extrude in the outer thickness of armour be the layer of polyester fiber of 5mm, waterproof material is filled with between armour and copper core, armour is made up of many aluminium strip spiral winding bags.
As preferably, insulating barrier is crosslinked polyethylene or hard ethylene-propylene rubber.
As preferably, water blocking layer is wrapped non-conductive waterstop outside insulating barrier.
As preferably, closed metal cover for thickness be the Resisting fractre metallic sheath of 1.5mm.
The utility model beneficial effect: the utility model is by changing the structure of copper conductor, and set up LSOH anti-flaming layer or low smoke, zero halogen fire insulation band improves fire resistance greatly, and realize when breakdown fault appears in insulation by arranging closed metal cover, because conductor and metallic sheath constitute galvanic circle, by existing cable fault locator, failure judgement point position, discharges fault rapidly immediately.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
