Abstract
The utility model relates to a cross-linked polyethylene insulated power cable which comprises a cross-linked polyethylene sheath, a magnetic shielding layer and a power cable core group which are successively arranged from outside to inside. A support sleeve group is arranged between the cross-linked polyethylene sheath and the magnetic shielding layer. The support sleeve group is formed by several high-density polyethylene resin support strips rotating around the central axis of the cable, and cross section of the high-density polyethylene resin support strips is an ellipsoidal structure. The power cable core group is formed by five cable cores rotating around the central axis of the cable. A rubber support sleeve is arranged at the center of the five cable cores. Several polyurethane support core strips are disposed inside the rubber support sleeve. The cross-linked polyethylene insulated power cable has a simple structure. By arranging the support sleeve group with flexible supporting capacity on the outside and by arranging the polyurethane support core strips for raising toughness at the center, toughness and strength of the cable can be raised, and application range of the cable is broadened.
Description
Technical field
The utility model relates to a kind of crosslinked polyethylene insulated power cable.
Background technology
In known technical field, crosslinked polyethylene insulated power cable not only has good electrical insulation properties, heat resistance, and mounting and installation do not limit by drop, so obtained in recent years developing rapidly and using.At present, the basic structure of crosslinked polyethylene insulated power cable is: conductor, be coated on the conductor shield and the insulating barrier that is coated on conductor shield outer surface of conductor outer surface, and wrapping is at the insulation screen of insulating barrier outer surface, wherein, insulating barrier is the key component that ensures the normal work of cable, and it is determining useful life of cable.Meanwhile, the support toughness of crosslinked polyethylene insulated power cable is also very important.
Utility model content
The technical problems to be solved in the utility model is: a kind of crosslinked polyethylene insulated power cable that toughness is good that supports is provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of crosslinked polyethylene insulated power cable, include outer in the crosslinked polyethylene sheath that sets gradually, magnetic masking layer and power electric cable core group, between described crosslinked polyethylene sheath and magnetic masking layer, be provided with support set group, described support set group is rotated distribution centered by the central axis of cable by some high-density polyethylene resin support bars, and the cross section of described high-density polyethylene resin support bar is ellipsoidal structure, described power electric cable core group is rotated distribution and is formed centered by the central axis of cable by 5 cable cores, be provided with rubber cover at the center of described 5 cable cores, in described rubber cover, be provided with some polyurethane supporting-core bars, between the inner side of overlapping in described rubber and polyurethane supporting-core bar, be filled with high temperature resistant gypsic horizon.
Further, as a kind of concrete execution mode, the thickness of the sheath of crosslinked polyethylene described in the utility model, magnetic masking layer and power electric cable core group is followed successively by 1.5mm, 2mm and 2mm.
