Description
Technical field
The present invention relates to a kind of cable, be specifically related to a kind of power 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.
At present, the cable on market is various, and they are applied in various different occasions.But all there are some problems in most of cable, such as layer of structure arranges unreasonable, compact not between layers, conductor shape is more single, and packed layer is solid not firmly, and filling effect is not good, insulating barrier insulation effect is undesirable, and restrictive coating is fragile, and whole service life is shorter.
Summary of the invention
Goal of the invention: the object of the invention is, in order to overcome deficiency of the prior art, provides a kind of compact conformation, long service life, bulk strength is high, non-damageable PVC insulated power cable.
Technical scheme: in order to solve the problems of the technologies described above, a kind of PVC insulated power cable of the present invention, it comprises conductor, be provided with insulating barrier in described conductor outside, be provided with packed layer in described insulating barrier outside, be provided with belting layer in described packed layer outside, be provided with external sheath layer in described belting layer outside, the thickness of described insulating barrier is between 0.8-2.4mm, and the thickness of described external sheath layer is between 1.8-2.7mm, and the diameter of described conductor is between 1.38-20.5mm.
Described conductor is for pressing circular stranded conductor or pressing sector conductor, and is at least one.
Described conductor is copper conductor or aluminium conductor.
Described insulating barrier is polyvinyl chloride insulation layer.
Described packed layer is composite material of silicon carbide packed layer.
Described belting layer is polyester belt lapping layer.
Described external sheath layer is polyvinyl chloride or polyethylene or halogen-free and low-smoke flame-retardant polyolefin sheathed layer.
When conductor of the present invention is one, do not need to use packed layer.
Conductor of the present invention can all use and press circular stranded conductor, also can all use and press sector conductor, can also press circular stranded conductor and press sector conductor to be used in conjunction with, for meeting different instructions for uses.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: compact overall structure of the present invention, between each layer, be connected, reliable, adopt the insulating barrier between 0.8-2.4mm, can effectively ensure insulation effect, adopt the external sheath layer between 1.8-2.7mm, can ensure that cable outside is more solid firmly, not fragile, adopt composite material of silicon carbide packed layer, can effectively improve filling effect, adopt halogen-free and low-smoke flame-retardant polyolefin sheathed layer, can improve cable result of use, integral product is longer useful life, realistic instructions for use.
Brief description of the drawings
Fig. 1 is the structural representation that the present invention's two cores press circular stranded conductor.
Wherein:
1, conductor; 2, insulating barrier; 3, packed layer; 4, belting layer; 5, external sheath layer
Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in Figure 1, a kind of PVC insulated power cable of the present invention, it comprises conductor 1, be provided with insulating barrier 2 in described conductor 1 outside, be provided with packed layer 3 in described insulating barrier 2 outsides, be provided with belting layer 4 in described packed layer 3 outsides, be provided with external sheath layer 5 in described belting layer 4 outsides, the thickness of described insulating barrier 2 is between 0.8-2.4mm, and the thickness of described external sheath layer 5 is between 1.8-2.7mm, and the diameter of described conductor 1 is between 1.38-20.5mm; Described conductor 1 is for pressing circular stranded conductor or pressing sector conductor, and is at least one; Described conductor 1 is copper conductor or aluminium conductor; Described insulating barrier 2 is polyvinyl chloride insulation layer; Described packed layer 3 is composite material of silicon carbide packed layer; Described belting layer 4 is polyester belt lapping layer; Described external sheath layer 5 is polyvinyl chloride or polyethylene or halogen-free and low-smoke flame-retardant polyolefin sheathed layer.Compact overall structure of the present invention, is connected between each layer, reliable, adopt the insulating barrier between 0.8-2.4mm, can effectively ensure insulation effect, adopt the external sheath layer between 1.8-2.7mm, can ensure that cable outside is more solid firmly, not fragile, adopt composite material of silicon carbide packed layer, can effectively improve filling effect, adopt halogen-free and low-smoke flame-retardant polyolefin sheathed layer, can improve cable result of use, integral product is longer useful life, realistic instructions for use.
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 is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art, under the premise without departing from the principles 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.
