Abstract
The invention discloses a direct current traction flame-retardant power cable of 1500V or below for rail transit. The direct current traction flame-retardant power cable sequentially comprises a copper conductor, an insulating layer, a water-resisting layer, a sealed metal sleeve and a thermoplastic or thermosetting sheath layer from the center to an outer layer, wherein the insulating layer is arranged outside the copper conductor in an extruded manner; the water-resisting layer wraps the outside of the insulating layer; the sealed metal sleeve sleeves the water-resisting layer; and the thermoplastic or thermosetting sheath layer is arranged on the sealed metal sleeve in the extruded manner; the copper conductor comprises five twisted copper cores, an armor layer and a polyester fiber layer; the armor layer wraps the outside of the copper cores; and the polyester fiber layer is arranged outside the armor layer in the extruded manner and is 5mm in thickness; a waterproof material is filled between the armor layer and the copper cores; the armor layer is formed by spirally wrapping a plurality of aluminum strips; and a non-halogen and low-smoke flame-retardant layer is arranged outside the water-resisting layer in the extended manner or a non-absorbent non-halogen and low-smoke fire protection strip wraps the outside of the water-resisting layer. The direct current traction flame-retardant power cable is simple in structure, has good flame retardant property and waterproof property, can immediately judge the position of a fault point when a breakdown fault occurs in insulation, and can quickly eliminate the fault.
Description
Technical field
The present invention relates to power cable for rail transit, particularly relate 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 present invention is directed to 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 object of the invention, 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 ethylene-propylene rubber 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.
Beneficial effect of the present invention: the present invention 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 structural representation of the present invention.
