Abstract
The invention relates to a novel aerial insulated cable which comprises three conductors. The three conductors form a triangular structure. Insulating layers are arranged outside the conductors, identification strips are arranged on the insulating layers positioned outside the conductors, a load bearing core is arranged at the top of the triangular structure formed by the conductors, a packing layer is arranged outside the load bearing core and the conductors, a wrapping layer is arranged outside the packing layer, a shielding layer is arranged outside the wrapping layer, and a sheath layer is arranged outside the shielding layer. The novel aerial insulated cable is novel in structure, diversified in functions and high in whole product strength.
Description
Technical field
The present invention relates to a kind of cable, be specifically related to a kind of aerial cable.
Background technology
Along with the fast development of national economy, as the aortal electric wire of national economy, its consumption and the scope of application are increasing.In recent years, the industries such as power plant, transformer station, smelting and petrochemical industry, very big to the demand of cable.
Aerial insulated cable is mainly used in avenue and greening location, near the overhead transmission line of building, and power supply safety and operational management is required the rural area wide geographic area that improves constantly, is particluarly suitable for thickly populated city, small towns and green belt and uses.Can dwindle spacing and the parallel distance of cable infall behind the use aerial insulated cable, lay conveniently, flexibility is high, reduces the space passage that takies, and can reduce widely frequency of power cut and the electric shock accidents that causes because of line fault, improve the safety and reliability of electrical network.But present aerial cable structure is more single, and structural strength is lower, and function is also more single.
In sum, necessaryly provide a kind of structural strength high, multiple functional, can adapt to the aerial cable of multiple environment.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of novel structure in order to overcome deficiency of the prior art, functional diversities, the Novel overhead insulated cable that integral product intensity is higher.
Technical scheme: in order to solve the problems of the technologies described above, a kind of Novel overhead insulated cable of the present invention, it comprises three conductors, described three conductors consist of triangular structure, outside every conductor, be provided with insulating barrier, all be provided with the identification band on the insulating barrier outside every conductor, the top of the triangular structure that consists of at described conductor is provided with load bearing core, be provided with packed layer at described conductor and load bearing core outside, outside described packed layer, be provided with lapping layer, outside described lapping layer, be provided with screen, outside described screen, be provided with restrictive coating.
Described insulating barrier is black crosslinkable polyethylene layer or weatherability black PVC layer, and its thickness is 0.5mm.
Described screen is semiconductive conductor screen material screen, and its thickness is 0.6mm.
Described packed layer is composite material of silicon carbide packed layer or asbestos packed layer.
Described lapping layer is the polyester belt lapping layer.
Described restrictive coating is flexible polyvinyl chloride restrictive coating or halogen-free and low-smoke flame-retardant polyolefin sheathed layer.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: structure of the present invention is relatively novel, adds the intensity that load bearing core has improved product greatly, has improved useful life.
Description of drawings
Fig. 1 is structural representation of the present invention.
Wherein:
1, conductor; 2, insulating barrier; 3, identification band; 4, load bearing core; 5, packed layer; 6, lapping layer; 7, screen; 8, restrictive coating
Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of Novel overhead insulated cable of the present invention, it comprises three conductors 1, described three conductors 1 consist of triangular structure, outside every conductor 1, be provided with insulating barrier 2, all be provided with identification on the insulating barrier 2 outside every conductor 1 and be with 3, the top of the triangular structure that consists of at described conductor 1 is provided with load bearing core 4, be provided with packed layer 5 at described conductor 1 and load bearing core 4 outsides, outside described packed layer 5, be provided with lapping layer 6, outside described lapping layer 6, be provided with screen 7, outside described screen 7, be provided with restrictive coating 8; Described insulating barrier 2 is black crosslinkable polyethylene layer or weatherability black PVC layer, and its thickness is 0.5mm; Described screen 7 is semiconductive conductor screen material screen, and its thickness is 0.6mm; Described packed layer 5 is composite material of silicon carbide packed layer or asbestos packed layer; Described lapping layer 6 is the polyester belt lapping layer; Described restrictive coating 8 is flexible polyvinyl chloride restrictive coating or halogen-free and low-smoke flame-retardant polyolefin sheathed layer.Structure of the present invention is relatively more novel, adopts load bearing core, has greatly improved the intensity of product; Adopt semiconductive conductor screen material screen, can improve shield effectiveness, adopt halogen-free and low-smoke flame-retardant polyolefin sheathed layer, can improve the anti-flammability of product.
The part that the present invention does not relate to all prior art that maybe can adopt same as the prior art is realized.
