Abstract
The invention discloses a direct-current traction anti-twist power cable up to 1500V for rail transit. The direct-current traction anti-twist power cable comprises a copper conductor, wherein a shielding layer, an insulating layer and a protective sheath sequentially coat the outside of the copper conductor; and the protective sheath is filled with a group of metal wires. Compared with the prior art, through a design of adding the metal wires, the cable is always in a stable state under the action of gravity, can generate a certain deflection when a vehicle passes through a rail, but still returns to an original state under the action of the gravity after a passenger car passes, so that the condition that the cable is not twisted off due to long-term stress is ensured.
Description
Technical field
The invention belongs to field of cables, be specifically related to that a kind of track traffic 1500V and following DC traction are anti-twists into two parts 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, its structure is followed successively by from center to skin: cable copper conductor, the insulating barrier of the crosslinked polyethylene extruded or ethylene-propylene rubber or hard ethylene-propylene rubber.When needed, water blocking layer can be had; When needed, watertight composition can be had; When needed, refuge floor can be had; When needed, armour can be had; When needed, the protection overcoat adding chemical agent can be had.According to demand, design different material layers, but can be stressed after cable laying, and As time goes on, cable may rotate when after rotation excessively, may cause twisting into two parts of cable.
Summary of the invention
Goal of the invention: the object of the invention is to for the deficiencies in the prior art, provides a kind of track traffic 1500V and following DC traction to prevent twisting into two parts power cable.
Technical scheme: in order to reach foregoing invention object; the present invention has specifically come like this: a kind of track traffic 1500V and following DC traction prevent twisting into two parts power cable; comprise copper conductor; copper conductor is coated with screen, insulating barrier and protective sleeve outward successively, is filled with one group of wire in described protective sleeve.
Wherein, described insulating barrier is polyethylene or polypropylene insulation layer.
Wherein, described number wiry is not more than 6, and the spacing between adjacent 2 wire is less than 0.5cm.
Beneficial effect: the present invention is compared with conventional art, by adding design wiry, cable is made to be in a stable state under gravity all the time, although may track have car by time produce certain deflection, but passenger vehicle is through still getting back to original state under gravity later, ensure that cable can not be twisted into two parts because of stressed causing for a long time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
