Abstract

The utility model discloses an explosion-proof heating oval cable comprising a cable core, wherein the cable core is constituted by two alloy conductors placed in parallel, each alloy conductor is formed by twisting a plurality of strands of tinned soft alloy wires and is internally provided with an oval tensile copper wire, the cable core is coated with a heating layer made of polymer PTC heating material, the heating layer is coated with a buffer layer made of foaming material, the buffer layer is sequentially coated with an armor layer and a fluorine plastic outer sheath layer, and the armor layer is braided with alloy wires. The explosion-proof heating oval cable can be normally used in a variety of harsh environments and can be used in occasions with explosion-proof requirements, and the adaptability of communication transmission to external environments is effectively improved.

Description

The oval cable of a kind of explosion-proof fever type

Technical field

The utility model relates to a kind of cable, is specially the oval cable of a kind of explosion-proof fever type.

Background technology

Cable is used widely in the communications field as a kind of data transmission media, has characteristics such as transmission speed is fast, efficient height.

Yet existing common cable operating position under adverse circumstances is not good, and as under high temperature, highly corrosive condition, the protective layer of existing cable is easily softening and corroded, when serious even influence the normal result of use of cable.

The utility model content

In order to solve the prior art problem, the purpose of this utility model provides the oval cable of a kind of explosion-proof fever type, is subjected to easily normally using under the influence of external environment factors such as high temperature, highly corrosive under adverse circumstances.

For achieving the above object, the technical solution adopted in the utility model is:

The oval cable of explosion-proof fever type, it is characterized in that: the alloy conductor that includes the parallel placement of two cores constitutes cable core, alloy conductor is closed by the zinc-plated mild alloy skein silk of multiply and forms, be provided with oval-shaped tension copper wire in the alloy conductor, cable core is coated with the heating layer that the high molecular PTC exothermic material constitutes, heating layer is coated with the resilient coating that expanded material is made, and resilient coating is coated with armour, the fluoroplastics external sheath layer that the braiding of alloy silk constitutes outward successively.

The oval cable of described explosion-proof fever type is characterized in that: described fluoroplastics external sheath layer cross section is for oval.

The oval cable of described explosion-proof fever type, it is characterized in that: the count of described armour is not less than 80%.

The beneficial effects of the utility model are:

1, the zinc-plated mild alloy skein silk of conductor part employing multiply closes and forms, and has guaranteed that conductor has the softness of Corrosion Protection and cable;

2, resilient coating adopts expanded material to make, and inner heating layer has been played the effect of insulation blocking;

3, armour cooperates resilient coating can resist external mechanical collision and increases cable tensile strength.

Fig. 1 is structural representation of the present utility model.

Embodiment

As shown in Figure 1:

The oval cable of explosion-proof fever type, the alloy conductor 1 that includes the parallel placement of two cores constitutes cable core, alloy conductor 1 is closed by the zinc-plated mild alloy skein silk of multiply and forms, be provided with oval-shaped tension copper wire 2 in the alloy conductor 1, cable core is coated with the heating layer 3 that the high molecular PTC exothermic material constitutes, it is crosslinked through electron accelerator irradiation that the high molecular PTC exothermic material draws back formation heating layer 3, interrupt the original strand of material and make its molecular structure reorganization, form a kind of stable heatable material, heating layer 3 is coated with the resilient coating 4 that expanded material is made, the resilient coating 4 outer armours 5 that are coated with alloy silk braiding formation successively, fluoroplastics external sheath layer 6.

Fluoroplastics external sheath layer 6 cross sections are oval.

The count of armour 5 is not less than 80%, has improved the mechanical strength of cable.
