Description

A kind of fire prevention tension power supply line
Technical field
The utility model belongs to power supply line technical field, and in particular to a kind of fire prevention tension power supply line.
Background technique
In China, wire and cable is defined such that wire and cable i.e. to transmit electric energy, information and realize that electromagnetic energy turns The wire product changed.Can also be defined as, be by one or more core and they respectively have from have insulating layer, protection Aggregate (the bare wire to transmit electric energy, information and realization electromagnetic energy conversion of the components such as layer, shielded layer, restrictive coating composition Except class).
There are many problems in current power supply line, if power supply line tensile strength is not high enough, vulnerable to external force in use And cause internal structure displacement even to damage, and inadequate to the buffering of external force or internal expansion, easily cause part cracks or curved It is bad to lose bad and power supply line fire protecting performance.
Utility model content
It is mentioned above in the background art to solve the purpose of this utility model is to provide a kind of fire prevention tension power supply line Power supply line tensile strength is not high enough, causes internal structure displacement even to damage vulnerable to external force, and to external force or inside The buffering of expansion is inadequate, easily causes part cracks or bending damage and the bad problem of power supply line fire protecting performance.
To achieve the above object, the utility model provides the following technical solutions: a kind of fire prevention tension power supply line, includes outer Sheath, fireprotection layer, shielded layer and separator, successively cladding is set from outside to inside for the oversheath, fireprotection layer, shielded layer and separator It sets;
Uniform intervals are provided with several grooves on the separator, and the first filled layer, insulation are provided in the groove Layer and conductor thread core, the successively cladding setting from outside to inside of first filled layer, insulating layer and conductor thread core;
It is provided centrally with cavity in the separator, the second filled layer and tensile reinforcement member, institute are provided in the cavity The second filled layer is stated to be coated on outside tensile reinforcement member.
Preferably, the material of the fireprotection layer is Ceramic silicon rubber.
Preferably, the material of first filled layer and the second filled layer is pp rope.
Preferably, the tensile reinforcement member is steel wire.
Preferably, the material of the separator is PVC.
Preferably, the shielded layer is braiding layer.
The utility model has the advantages that
(1) a kind of fire prevention tension power supply line of the utility model, the design of separator and tensile reinforcement member enhance power supply The tensile capacity of line, and reduce influencing each other between conductor thread core, it prevents from being caused power supply line internal junction by external force Structure displacement even damages;The design of first filled layer and the second filled layer enhances power supply line to external force or internal expansion Buffer capacity prevents part cracks or bending damage.
(2) a kind of fire prevention tension power supply line of the utility model, is provided with fireprotection layer between oversheath and shielded layer, improve The fire resistance property of power supply line.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
In figure: 1- oversheath, 2- fireprotection layer, 3- shielded layer, 4- separator, the first filled layer of 5-, 6- insulating layer, 7- conductor Core, the second filled layer of 8-, 9- tensile reinforcement member.
Specific embodiment
The embodiments of the present invention are further illustrated with reference to the accompanying drawing.
It include oversheath 1, fireprotection layer 2, shielded layer 3 and separator 4 as shown in Figure 1, a kind of fire prevention tension power supply line, The successively cladding setting from outside to inside of the oversheath 1, fireprotection layer 2, shielded layer 3 and separator 4;
