Abstract
The utility model discloses a resistance to compression cable aims at providing a resistance to compression cable that structural strength is high, and it includes many sinle silks and arranges the outer insulating layer of sinle silk in, still includes filling layer, resistance to compression layer and oversheath. The method is characterized in that: still include the support frame, the support frame is by hollow main part and the backup pad of arranging around main part periphery wall equidistance, forms the chamber that holds that is used for placing the sinle silk between the double-phase adjacent backup pad, and every holds the intracavity and fills with the filling layer, and the cladding has the compressive layer in the periphery of support frame, has a plurality of recess on the outer circumference of compressive layer, has the function of absorption deformation, has the oversheath outside the compressive layer. The utility model discloses have higher compressive capacity, can bear external great pressure and do not damage.
Description
Technical Field
The utility model relates to the technical field of cables, in particular to cable with resistance to compression function.
Background
Compared with an overhead line, the cable has the advantages of small insulating distance between lines, small occupied space, no occupation of space above the ground due to underground laying, no influence of surrounding environment pollution, high power transmission reliability, and small interference on personal safety and surrounding environment.
However, the cable is usually installed in a building or buried underground, and the conventional cable has a general pressure-bearing capacity and is easily damaged or broken by external pressure, so that the service life and safety of the cable are seriously affected.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide a structural strength is high, easily disperse external pressure's resistance to compression cable.
In order to achieve the above purpose, the utility model provides a following technical scheme: a compression-resistant cable comprises a plurality of wire cores, an insulating layer arranged outside the wire cores, a support frame and a compression-resistant layer and an outer sheath, wherein the insulating layer is made of polyvinyl chloride, the compression-resistant layer and the outer sheath are arranged on the support frame, the support frame is composed of a hollow main body and support plates which are distributed around the peripheral wall of the main body at equal intervals, a containing cavity for containing the wire cores is formed between every two adjacent support plates, the containing cavity is filled with the filling layer, the filling layer is made of glass fiber silk materials and has good insulativity and heat resistance and high tensile strength and compressive strength, the outer periphery of the support frame is coated with the compression-resistant layer, the outer periphery of the compression-resistant layer is provided with a plurality of grooves which have the function of absorbing deformation, the compression-resistant layer is made of fluorosilicone rubber material, the flexibility and elasticity of the fluorosilicone rubber material are good, the support frame is easy to deform under external force, further, the outer sheath is made of polyvinyl chloride.
Furthermore, the material of support frame is the non-metallic material that intensity is higher, and the backup pad quantity on it is 3 ~ 6.
Through adopting above-mentioned technical scheme, the support frame plays the effect of separation protection to between the line core, and the structure of main part and backup pad can ensure that the support frame has good compressive strength, and cladding compressive layer on the periphery of support frame, play further fixed action to the line core, glass fiber fills in holding the intracavity, it is more solid to make to hold the intracavity, can play better protection effect to the line core, glass fiber can increase the stretch-proofing ability of cable for the long filament structure simultaneously, glass fiber has certain electromagnetic shielding effect in addition, the compressive layer outer circumference has the round recess, when being favorable to receiving external pressure, the deformation that the compressive layer can be better, thereby absorb and offset external pressure, improve the elasticity and the toughness of whole structure.
