Description
Technical field
The utility model relates to a kind of power transmission cable, relates in particular to a kind of high temperature resistant frequency conversion and moves flexible cable with self-bearing type.
Background technology
Variable-frequency control technique has obtained widely using in industrial aspect such as oil, metallurgy, generating, railway, mines, and also very wide as the market prospects of the frequency-changing cable of its auxiliary products.
Existing frequency-changing cable heat-resisting ability is poor, meets fire and promptly fires, and water is being arranged and having under the oily complex environment, and damage is easy to be corroded.
The utility model content
To the problems referred to above, the purpose of the utility model is to provide a kind of high temperature resistant frequency conversion to move flexible cable with self-bearing type, to solve problems of the prior art.
To achieve these goals, the technical scheme of the utility model is following:
High temperature resistant frequency conversion is moved flexible cable with self-bearing type; It is characterized in that, comprise the heart yearn assembly, said heart yearn assembly comprises a strengthening core that twists together, three main cores and three auxilliary cores; Said heart yearn assembly is outside equipped with interior separator; Separator is outside equipped with the copper strips screen in said, and said copper strips screen is outside equipped with outer separator, and the outside of said outer separator is provided with restrictive coating.
In an embodiment of the utility model, the gap location between said interior separator and the heart yearn assembly is provided with fire-retardant filler.
In an embodiment of the utility model, said restrictive coating is the silicone rubber jacket layer.
In an embodiment of the utility model, said inside and outside, separator is and adopts wrapped high flame retardant fire insulation glass cloth band, and is equipped with the fire lagging that mineral insulating material is filled.
The utlity model has the good temperature resistance ability.The separator of the utility model is to adopt wrapped high flame retardant fire insulation glass cloth band, and is equipped with mineral insulating material and fills, and therefore not only have the fireproof effect, and bending property is better.
Description of drawings
Specify the utility model below in conjunction with accompanying drawing and embodiment:
Fig. 1 is the structural representation of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, high temperature resistant frequency conversion is moved flexible cable with self-bearing type, comprises the heart yearn assembly, and the heart yearn assembly comprises a strengthening core twisting together 2, three main cores 1 and three auxilliary cores 3, and said heart yearn assembly is outside equipped with interior separator 5.Gap location between interior separator 5 and the heart yearn assembly is provided with fire-retardant filler 4.Fire-retardant filler 4 can be selected the glass rope for use.
The outside of outer separator 7 is provided with restrictive coating 8.Restrictive coating 8 is the silicone rubber jacket layer, strengthens ageing resistance.
The utlity model has the good temperature resistance ability.The separator of the utility model is to adopt wrapped high flame retardant fire insulation glass cloth band, and is equipped with mineral insulating material and fills, and therefore not only have the fireproof effect, and bending property is better.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The just principle of describing in the foregoing description and the specification of the utility model; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the scope of the utility model that requires protection.The protection range that the utility model requires is defined by appending claims and equivalent thereof.
