Description

A kind of copper core polyvinyl chloride insulating flexible cable
Technical field
The utility model belongs to cable machinery technical field, and in particular to a kind of copper core polyvinyl chloride insulating flexible cable.
Background technology
With the rapid development of science and technology, the usage amount of cable and all progressively expanded using scope, especially generated electricity The industries such as factory, transformer station, smelting and petrochemical industry, the various performances of cable there has also been very big progress, but cable security With durability all the time it is critical that.According to statistics, in the fire that each electric appliances of China cause in recent years, have 60% above is by What electric wire caused, the security for strengthening cable is imperative.Meanwhile, the laying of cable is a more complicated process, The frequent maintenance and replacing of cable can bring great trouble, cause the loss on human and material resources.Therefore, how cable is improved Security and durability be the problem for receiving significant attention.
Additionally, cable use it is widely available its range of application is also further increased, cable needs to adapt to various differences Environment, this also proposes new challenge to the security and durability of cable.
The content of the invention
The purpose of this utility model is to provide a kind of copper core polyvinyl chloride insulating flexible cable of safety durable.
For achieving the above object, the technical scheme that the utility model is used is:A kind of copper core polyvinyl chloride insulation Flexible cable, including many copper core conductors, the copper core conductor outside are provided with polyvinyl chloride insulation layer, in the polyvinyl chloride insulation Layer outside is sequentially provided with screen layer and polyvinyl chloride insulation sheath;Flexibility is provided between the polyvinyl chloride insulation layer and screen layer Packed layer, is provided with waterproof membrane and flame-retardant layer between the screen layer and polyvinyl chloride insulation sheath;
The polyvinyl chloride insulation sheath outside is provided with fixed cover, and the fixed cover is annular hollow structure, fixed cover Madial wall is the metallic plate with mesh, and lateral wall is the metal sleeve of closing;The metal sleeve is by upper sleeve pipe and setting of casing two Part constitutes, and the position that the upper sleeve pipe and setting of casing outside contact with each other is respectively provided with otic placode, and the otic placode is provided with fixing hole, Fixture between upper sleeve pipe and setting of casing by matching with fixing hole is attached and fixes;It is filled with the fixed cover Replaceable mould proof drier.
Preferably:Described flame-retardant layer is made up of silica gel fire prevention piece.
Preferably:The mesh aperture of described fixed cover madial wall is 1~2mm, the mould proof drier particle diameter filled More than 2mm.
Preferably:Permeable non-woven fabrics is laid between described fixed cover madial wall and mould proof drier.
The utility model has the advantages that:Multi-protective layer is set on the outside of copper core conductor and causes the utility model Safety durable, good stability, the fixed cover set in the outside of cable facilitates the fixation of cable.Meanwhile, filled in fixed cover Mould proof drier enables the utility model to be applied to various wet environments, expands its range of application.Additionally, flexible filling Layer and silica gel fire prevention piece all effects with damping compression-resistant, can bear the impulsive force of some strength, than general cable more Plus it is durable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is top view of the present utility model.
Specific embodiment
Copper core polyvinyl chloride insulating flexible cable as shown in Figure 1, including many copper core conductors 1, the outside of the copper core conductor 1 Polyvinyl chloride insulation layer 2 is provided with, screen layer 4 and polyvinyl chloride insulation shield are sequentially provided with the outside of polyvinyl chloride insulation layer 2 Set 7.The outside of every copper core conductor 1 is equipped with polyvinyl chloride insulation layer 2, prevents electric current from exposing, and screen layer 4 leads many copper cores In body 1 is wrapped in.
Further to protect cable, flexible packed layer 3 is provided between the polyvinyl chloride insulation layer 2 and screen layer 4, made many Root copper core conductor 1 is securely fixed in screen layer 4, also reduces influence of the foreign impacts power to copper core conductor 1.The shielding Waterproof membrane 5 and flame-retardant layer 6 are provided between layer 4 and polyvinyl chloride insulation sheath 7, make cable that there is waterproof, nonflammable function.Institute Effect of the flexible packed layer 3 with damping compression-resistant is stated, is filled with many polyvinyl chloride insulation layers 2 and screen of copper core conductor 1 Covering copper core conductor 1 can be protected still stable and firm in the presence of by certain external force between layer 4, is not damaged.Described Flame-retardant layer 6 can be made up of various material, such as magnesium hydroxide, aluminium hydroxide or organohalogen compounds, it is preferred that flame-retardant layer 6 are made up of silica gel fire prevention piece, and fireproof silica gel piece soft texture, it may have the effect of damping compression-resistant further enhancing cable Anti-pressure ability, can protect cable to make it have more preferable stability.
In order that the utility model is easily installed, the outside of the polyvinyl chloride insulation sheath 7 is provided with fixed cover, the fixation It is annular hollow structure to cover, and the madial wall of fixed cover is the metallic plate with mesh, and lateral wall is the metal sleeve of closing.The gold Category sleeve pipe is made up of upper sleeve pipe 8 and the two parts of setting of casing 9, and the position that the upper sleeve pipe 8 and the outside of setting of casing 9 contact with each other is all provided with Put otic placode 10, as shown in Fig. 2 the otic placode 10 is provided with fixing hole, between upper sleeve pipe 8 and setting of casing 9 by with fixing hole phase The fixture of matching is attached and fixes.The fixture can be the screw rod matched with fixing hole aperture, and screw rod is passed through Cable is fixed on institute's installation site by the otic placode 10 of upper pipe sleeve 8 and lower pipe sleeve 9.Or fixture is the stranded rope of wire Rope, rope passes through from the fixing hole of otic placode 10 and winds otic placode a few are locked by upper sleeve pipe 8 and setting of casing 9, then with cable The position installed carries out binding locking.
In order that the utility model can be applied to various environment, filled with replaceable mould proof dry in the fixed cover Drying prescription, when utility model is applied to moist, environment that is easily mildewing, can increase the quantity of fixed cover, the adjacent fixed cover of reduction Between spacing, and frequently change the mould proof drier filled.In order to prevent inner side of the mould proof drier from fixed cover Wall spills, and the mesh aperture of described fixed cover madial wall is 1~2mm, and the mould proof drier particle diameter filled is more than 2mm, Mould proof drier can be so kept to be located in fixed cover.Or spread between described fixed cover madial wall and mould proof drier If permeable non-woven fabrics, the moisture around its absorbing cable is neither influenceed, can kept it in fixed cover again.
