Abstract
The utility model discloses a crosslinking polyethylene insulated cable, which comprises conductors. An insulating layer made of crosslinking polyethylene materials is arranged on the outer side of each conductor. A filling layer, a tape wrapping layer and an outer sheath are together arranged outside the conductors provided with the insulating layers. A water resistant layer made of polyester fiber weaved cloth and high water-absorption materials in a composite way and a water proof layer made of plastic-aluminum composite belts are arranged between the tape wrapping layer and the outer sheath. The crosslinking polyethylene insulated cable provided by the utility model solves the waterproof insulation efficacy problem during a using process. The service lifetime of the cable in a humid condition can be prolonged. Meanwhile, the signal transmission stability problem is also solved.
Description
Technical field
The utility model relates to a kind of field of cables, is specifically related to cross-linked polyethylene insulated cable.
Background technology
Along with the development of cable with popularize, the cable security possibility that is used for electric equipment requires also more and more higher, the environment for use of polyethylene insulated cable is very special, abominable, if cable uses operation under the environment of humidity, along with the extraneous moisture of the increase of service time can slowly be penetrated in the cable, in cable, can form the water shadow of the trees and ring cable problem in useful life, increase along with service time, finally may cause the puncture of insulating, thereby cause scrapping of cable, may bring the problems such as fault even potential safety hazard to electric equipment.
Summary of the invention
The purpose of this utility model is to provide a kind of cross-linked polyethylene insulated cable, efficiently solves waterproof insulation effect in use, has prolonged the life-span that cable uses under wet environment, the problems such as stable signal transmission.
To achieve these goals, this uses the technical scheme of novel proposition to be:
Cross-linked polyethylene insulated cable, include conductor, outside every described conductor, be provided with the insulating barrier that adopts cross-linking polyethylene materials to make, a plurality of conductors that are provided with insulating barrier are provided with packed layer, belting layer, oversheath outward jointly, are provided with the watertight composition of being made by polyester fiber woven cloths and the compounded water blocking layer of high-absorbent material, employing aluminium-plastic tape between described belting layer and oversheath.
As the further improved cross-linked polyethylene insulated cable of the utility model, described conductor is to be made by 3 copper cores or aluminium core, and described oversheath adopts cross-linking polyethylene materials to be made.
Cross-linked polyethylene insulated cable provided by the utility model has solved waterproof insulation effect in use, has prolonged the life-span that cable uses under wet environment, the problems such as stable signal transmission.
Description of drawings
Fig. 1, the cross-linked polyethylene insulated cable perspective view.
1 is conductor, and 2 is insulating barrier, and 3 is packed layer, and 4 is belting layer, and 5 is water blocking layer, and 6 is watertight composition, and 7 is oversheath.
Embodiment
In order to deepen understanding of the present utility model, the utility model is done describing in further detail below in conjunction with drawings and Examples, this embodiment only is used for explaining the utility model, does not consist of the restriction to the utility model protection range.
As shown in Figure 1, the cross-linked polyethylene insulated cable that present embodiment provides, include conductor 1, described conductor 1 is to be made by 3 copper cores or aluminium core, outside every described conductor 1, be provided with the insulating barrier 2 that adopts cross-linking polyethylene materials to make, a plurality of conductor 1 outer packed layers 3 that jointly are provided with that are provided with insulating barrier 2, belting layer 4, oversheath 7, described oversheath 7 adopts cross-linking polyethylene materials to be made, good flame retardation effect has prolonged the useful life of cable, between described belting layer 4 and oversheath 7, be provided with by polyester fiber woven cloths and the compounded water blocking layer 5 of high-absorbent material, the watertight composition 6 that adopts aluminium-plastic tape to make, described by polyester fiber woven cloths and the compounded water blocking layer 5 of high-absorbent material when cable end has moisture to invade, form full-closed structure and contained high suction powder, can expand rapidly and become gelinite, stop water further vertically deeply, guaranteed the electrical insulation properties of cable, the watertight composition that described employing aluminium-plastic tape is made can play anti-sealing and radially enter cable inside.
