Abstract
The invention relates to a multi-core control cable, which comprises a conductor, wherein an insulation layer is arranged outside the conductor, a filling layer is arranged outside the insulation layer, an inner jacket layer is arranged outside the filling layer, a steel-wire armored layer is arranged outside the inner jacket layer, copper wires are uniformly arranged inside the steel-wire armored layer, and an outer jacket layer is arranged outside the steel-wire armored layer. The multi-core control cable is high in strength, good in insulation flame retardant effect and strong in reliability.
Description
Technical field
The present invention relates to a kind of cable, be specifically related to a kind of control cables.
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.
The general control cable generally adopts polyvinyl chloride as insulation at present, and sheath material is cross-linked polrvinyl chloride.This control cables is owing to its design feature, and whole reliability is not strong, does not have simultaneously good intensity.When fire occured, the general control cable can't guarantee that circuit works on.In addition, the copper core copper sheath magnesium oxide insulating cable on the market because adopt drawing process and with magnesium oxide as cable insulation, the cable core radical is restricted, its insulating reliability is also very poor.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of intensity higher in order to overcome deficiency of the prior art, and flame-resistant insulation is effective, the multi-core controlled cable that reliability is strong.
Technical scheme: in order to solve the problems of the technologies described above, a kind of multi-core controlled cable of the present invention, it comprises conductor, outside described conductor, be provided with insulating barrier, outside described insulating barrier, be provided with packed layer, outside described packed layer, be provided with inner restrictive coating, outside described inner restrictive coating, be provided with the wire armoring layer, in described wire armoring layer, evenly be provided with copper wire, outside described wire armoring layer, be provided with external sheath layer.
Described conductor is seven.
Described conductor is copper conductor or aluminium conductor.
Described insulating barrier is weatherability black PVC layer.
Described packed layer is composite material of silicon carbide packed layer or asbestos packed layer.
Described external sheath layer is halogen-free and low-smoke flame-retardant polyolefin sheathed layer.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: insulating barrier of the present invention adopts weatherability black PVC layer, improved insulation effect, packed layer adopts the composite material of silicon carbide packed layer, greatly improve filling effect, in the wire armoring layer, evenly be provided with copper wire, greatly improved whole intensity, external sheath layer adopts halogen-free and low-smoke flame-retardant polyolefin sheathed layer, has greatly improved flame retardant effect.

Fig. 1 is structural representation of the present invention.
Wherein:
1, conductor; 2, insulating barrier; 3, packed layer; 4, inner restrictive coating; 5, wire armoring layer; 6, copper wire; 7, external sheath layer
Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of multi-core controlled cable of the present invention, it comprises conductor 1, outside described conductor 1, be provided with insulating barrier 2, outside described insulating barrier 2, be provided with packed layer 3, outside described packed layer 3, be provided with inner restrictive coating 4, outside described inner restrictive coating 4, be provided with wire armoring layer 5, at the described wire armoring layer 5 interior copper wire 6 that evenly is provided with, outside described wire armoring layer 5, be provided with external sheath layer 7; Described conductor 1 is seven; Described conductor 1 is copper conductor or aluminium conductor; Described insulating barrier 2 is weatherability black PVC layer; Described packed layer 3 is composite material of silicon carbide packed layer or asbestos packed layer; Described external sheath layer 7 is halogen-free and low-smoke flame-retardant polyolefin sheathed layer.Insulating barrier of the present invention adopts weatherability black PVC layer, improved insulation effect, packed layer adopts the composite material of silicon carbide packed layer, greatly improved filling effect, in the wire armoring layer, evenly be provided with copper wire, greatly improved whole intensity, external sheath layer adopts halogen-free and low-smoke flame-retardant polyolefin sheathed layer, has greatly improved flame retardant effect.
The invention provides a kind of thinking and method; method and the approach of this technical scheme of specific implementation are a lot; the above only is preferred implementation of the present invention; should be understood that; for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications; these improvements and modifications also should be considered as protection scope of the present invention, in the present embodiment not clear and definite each part all available prior art realized.
