Abstract
The utility model discloses a coaxial power cable with a flexible compressive structure. The coaxial power cable comprises three inner conductors; the exteriors of the three inner conductors are respectively coated with a polyvinyl chloride insulation layer, such that three insulated inner cores can be formed; the three insulated inner cores are distributed in a manner that the three insulated inner cores form a structure shaped like a Chinese character ''pin'' so as to form a cable core; a bar-shaped compressive supporting body of which the section is Y-shaped is arranged at the center of the cable core; a plurality of through holes are distributed inside the bar-shaped compressive supporting body along the direction of a central line; the exterior of the cable core is provided with a belt wrapping layer; the exterior of the belt wrapping layer is provided with a liner; the exterior of the liner is provided with a carrier layer; a plurality of outer conductors in annular distribution are arranged inside the carrier layer; the exterior of the outer conductors is provided with a winding layer; and the exterior of the winding layer is wrapped with an outer sheath layer. The coaxial power cable of the utility model is novel in structure design. According to the coaxial power cable of the utility model, the Y-shaped and bar-shaped compressive supporting body is designed, and structures such as the carrier layer, the liner and the winding layer also designed in a matched manner, and therefore, the conductors of the cable can be excellently protected and have little possibility of being damaged; and further, the cable is advantageous in uniform and lower positive (reverse)/zero sequence impedance, sensitive action of a short-circuit automatic protection device and the like.
Description
technical field:
The utility model relates to power cable, relates in particular to a kind of coaxial power cable with flexible compression-resistant structure.
background technology:
The a lot of operating characteristics of common three-core cable are poor, such as higher and inhomogeneous just (contrary) order and zero sequence working impedance, and the action of short circuit automatic safety device is insensitive etc., under actual working environment, can not meet work requirements.
Therefore, in these cases, mostly adopt coaxial cable.When meeting above-mentioned requirements, but there is the very easily impaired problem of cable core in current coaxial cable, can not guarantee long-term use in practical service environment, need to often change, and increased cost.
utility model content:
In order to make up prior art problem; the purpose of this utility model is to provide a kind of coaxial power cable with flexible compression-resistant structure; have even and lower just (contrary) order and zero sequence working impedance, being active in one's movements of short circuit automatic safety device, can be good at protecting cable conductor not easily damaged.
The technical solution of the utility model is as follows:
Coaxial power cable with flexible compression-resistant structure, comprise three inner wires, it is characterized in that: three described inner wires are coated with respectively polyvinyl chloride insulation layer outward and form three eradication edge inner cores, three thoroughly do away with edge inner core with the formation cable core that distributes in a triangle, cable core center is provided with the bar shaped resistance to compression supporter that cross section is Y shape, bar shaped resistance to compression supporter adopts olefin hydrocarbons thermoplasticity elastic body material extrusion moulding, in bar shaped resistance to compression supporter, along centerline direction, be provided with several through holes, cable core is provided with belting layer outward, belting layer is provided with inner covering outward, inner covering is provided with carrier layer outward, carrier layer adopts silicon rubber extrusion moulding to form, in carrier layer, be provided with some along the outer conductor of annular spread, outer conductor is provided with winding layer outward, winding layer is coated with external sheath layer.
The described coaxial power cable with flexible compression-resistant structure, is characterized in that: described winding layer adopts ribbon spiral to be wound around formation, and the gap of spiral winding is not more than 3mm.
The utility model has the advantages that:
The utility model structural design is novel; by the bar shaped resistance to compression supporter of design Y shape; coordinate carrier layer, inner covering, the isostructural design of winding layer; can be good at protecting cable conductor not easily damaged; increase the service life; in addition, cable also has even and lower just (contrary) order and zero sequence working impedance, the characteristic such as be active in one's movements of short circuit automatic safety device.
