Description
Technical field
Field of cable technology is the utility model is related to, particularly a kind of high strength safe cable.
Background technology
Cable refers to the material for electric power, communication and associated transport purposes.With the development of society, cable uses model
Enclose, requirement to cable also more and more higher more and more with occasion.
Current cable generally existing on the market is counter-bending, impact resistance is poor, and deficiency is protected to the core in cable
Problem.
Utility model content
To solve problems of the prior art, the purpose of this utility model is to provide a kind of counter-bending, shock resistance energy
Power is strong, the core in cable is protected comprehensively, has electromagnetic shielding and fire-retardant high strength safe cable.
To achieve the above object, the technical solution adopted in the utility model is：A kind of high strength safe cable, including insulation
Layer, high-strength bone rack-layer, screen layer and core；The high-strength bone rack-layer is by two concentric and orthogonal oval ring groups
Into high-strength bone rack-layer is divided into center and four external zones around central area, the center by described two elliptical rings
Core is provided with area, the outer surface of the core is enclosed with screen layer, circular buffering tubing is provided with the external zones, described
High-strength bone rack-layer is externally provided with insulating barrier.
The high-strength bone rack-layer being made up of two concentric and orthogonal elliptical rings, when cable is extruded by external force,
The advanced row buffering of external zones that the both ends of two elliptical rings are formed, dynamics is such as extruded without excessive, can be pressed further by external zones
Interior buffering tubing, due to buffering the circular rock-steady structure of tubing, row buffering can be squeezed into outside again, prevent center
Core directly damaged by external impacts, simultaneously because the presence of high-strength bone rack-layer and separator tube material, the bend resistance energy of cable
Power also greatly improves, and the bending that external force can be avoided to be formed damages to core, and the screen layer on core surface uses electromagnetic shielding
Material, certain electromagnetic shielding action can be provided core, prevents outer signals from disturbing.
Preferably, the outer surface of the screen layer is enclosed with flame-retardant layer.Flame-retardant layer can prevent high-temp combustion core from causing electricity
Road failure.
Preferably, PP fill areas are provided with the internal voids of the high strength safe cable.Using PP to cable internal voids
It is filled, the intensity of cable can be increased, makes cable more tension bend resistance.
Preferably, the insulating barrier is crosslinked polyetylene insulated layer.The key property of crosslinked polyetylene insulated layer is it
Intensity and heat resistance, particularly its creep strength, its intensity is not notable with the change of usage time, the life-span up to 50 years it
Long.
The beneficial effects of the utility model are：High intensity skeleton is formed using two concentric and orthogonal elliptical rings
Layer, then buffering tubing is set wherein, considerably increase the intensity of cable, make the bend resistance of cable and impact resistance very big
Increase.

Embodiment
Embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
Embodiment
As shown in figure 1, a kind of high strength safe cable, including insulating barrier 1, high-strength bone rack-layer 2, screen layer 5 and core
6；The high-strength bone rack-layer 2 is made up of two concentric and orthogonal elliptical rings, and described two elliptical rings are by high intensity
Casing play 2 divides four external zones for center and around central area, and core 6 is provided with the center, the core 6
Outer surface is enclosed with screen layer 5, is provided with circular buffering tubing 3 in the external zones, the high-strength bone rack-layer 2 is externally provided with absolutely
Edge layer 1.
The high-strength bone rack-layer 2 being made up of two concentric and orthogonal elliptical rings, when cable is extruded by external force,
The advanced row buffering of external zones that the both ends of two elliptical rings are formed, dynamics is such as extruded without excessive, can be pressed further by external zones
Interior buffering tubing 3, due to buffering the circular rock-steady structure of tubing 3, row buffering can be squeezed into outside again, prevent center
The core 6 in area is directly damaged by external impacts, simultaneously because the presence of high-strength bone rack-layer 2 and separator tube material 3, the bending resistance of cable
Folding ability also greatly improves, and the bending that external force can be avoided to be formed damages to core 6, high-strength bone rack-layer 2 and separator tube material 3
Resin or elastomeric material can be used to make；The screen layer 5 on the surface of core 6 uses electromagnetic shielding material, can provide one to core 6
Fixed electromagnetic shielding action, prevents outer signals from disturbing.
In one of the embodiments, the outer surface of the screen layer 5 is enclosed with flame-retardant layer 4.Flame-retardant layer 4 can prevent high temperature
Burning core 6 causes fault.
In one of the embodiments, PP fill areas 7 are provided with the internal voids of the high strength safe cable.Use PP pairs
Cable internal voids are filled, and can increase the intensity of cable, make cable more tension bend resistance.
In one of the embodiments, the insulating barrier 1 is crosslinked polyetylene insulated layer.The weight of crosslinked polyetylene insulated layer
Characteristic is wanted to be its intensity and heat resistance, particularly its creep strength, its intensity is not notable with the change of usage time, the life-span
Up to 50 years as long as.
Embodiment described above only expresses specific embodiment of the present utility model, and its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to the utility model patent scope.It should be pointed out that for the common of this area
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the scope of protection of the utility model.
