Abstract
The utility model discloses a polrvinyl chloride (PVC) insulated and sheathed power cable which comprises three conductors having fan-shaped cross sections and a conductor having a circular cross section. The three conductors having fan-shaped cross sections and the conductor having a circular cross section are respectively and successively coated with a flame retardant coating and an insulating layer. After coated with the insulating layer, the flame retardant coating is vertically placed to form a notched cylinder. The conductor having a circular cross section is placed in the notch of the cylinder so as to form a cable core. The cable core is successively coated with an inner sheathing layer and a foaming layer. The thickness of the foaming layer is 2.0-3.8mm. A net-like reinforced layer braided by steel wires is arranged outside the foaming layer. An outer sheathing layer is subjected to extrusion molding outside the reinforced layer. After extrusion molding, the outer sheathing layer is integrated with the reinforced layer. The structure of the PVC insulated and sheathed power cable is reasonably designed. As the foaming layer and the reinforced layer are additionally arranged between the inner sheathing layer and the outer sheathing layer, on one hand, dead weight of the cable is effectively reduced, and on the other hand, the structure of the cable is made compact and its tensile strength is raised.
Description
Technical field:
The utility model relates to the power cable field, relates in particular to a kind of polyvinyl chloride insulation and sheath power cable.
Background technology:
Cable is in order to transmit electricity (magnetic) energy, the wire product of information and the conversion of realization electromagnetic energy.Normally by the cable of several or at least two every group stranded similar ropes that form of several groups of wires, mutually insulated between every group of wire, and often be twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.
Electric wire mainly comprises bare wire, electromagnetic wire and electrical equipment and electrical insulated electric conductor, power cable, telecommunication cable and optical cable.
It is on 0.6/1kv and the following electric line that the polyvinyl chloride power cable generally is applicable to ac rated voltage, cause being prone to disconnected core phenomenon because deadweight is large, mechanical performance is relatively poor in the general use procedure, so that interrupting appears in the information transmission, cause immeasurable economic loss.
The utility model content:
The purpose of this utility model provides a kind of polyvinyl chloride insulation and sheath power cable, and is simple in structure, easy to use, has lighter deadweight and good mechanical performance.
The technical solution of the utility model is as follows:
Polyvinyl chloride insulation and sheath power cable, it is characterized in that: comprise that three cross sections are fan-shaped conductor, a cross section is circular conductor, three cross sections are fan-shaped conductor, a cross section is enclosed with respectively flame retardant coating outward successively for circular conductor, insulating barrier, three cross sections behind the wrap insulate layer are that fan-shaped vertical the putting of conductor forms cylinder jaggy, placing a cross section in the breach of cylinder is that circular conductor consists of cable core, cable core is enclosed with inner restrictive coating outward successively, foaming layer, the thickness of foaming layer is 2.0～3.8mm, foaming layer is provided with the webbed reinforced layer of braided steel wire outward, the thickness of reinforced layer is 1.8～2.4mm, the outer extrusion molding of reinforced layer has external sheath layer, and external sheath layer forms one through extrusion moulding and reinforced layer.
Described polyvinyl chloride insulation and sheath power cable is characterized in that: described insulating barrier, inner restrictive coating, external sheath layer material adopt polyvinyl chloride.
The utility model has the advantages that:
The utility model reasonable in design, adopt the different conductor in cross section, between inner restrictive coating and external sheath layer, set up foaming layer and reinforced layer, the deadweight that has effectively alleviated cable on the one hand, on the other hand so that the compact tensile strength raising of the construction of cable, the cable core break phenomenon is eased, and information transmission stability is ensured reliably.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1:
Polyvinyl chloride insulation and sheath power cable, comprise that three cross sections are fan-shaped conductor 1, a cross section is circular conductor 2, three cross sections are fan-shaped conductor 1, a cross section is the circular conductor 2 outer flame retardant coatings 3 that are enclosed with successively respectively, insulating barrier 4, three cross sections behind the wrap insulate layer 4 are the fan-shaped conductor 1 vertical cylinder that is formed with breach 5 of putting, cross section of breach 5 interior placements of cylinder is that circular conductor 2 consists of cable core, cable core is enclosed with inner restrictive coating 6 outward successively, foaming layer 7, the thickness of foaming layer 7 is 2.0～3.8mm, the foaming layer 7 outer webbed reinforced layers 8 of braided steel wire that are provided with, the thickness of reinforced layer 8 is 1.8～2.4mm, reinforced layer 8 outer extrusion moldings have external sheath layer 9, and external sheath layer 9 forms one through extrusion moulding and reinforced layer 8.
