The utility model provides a shield constructs quick-witted special type cable, the anti back of strengthening the cable is turned round the function, reduces the cable and takes place relative displacement, reduces insulation core disconnection phenomenon. The reinforced braided layer made of aramid fiber yarns is added, the main function of the reinforced braided layer is to provide an anti-back-twist function for the cable, the reinforced braided layer has certain braided density to provide required mechanical performance, and the inner sheath and the outer sheath can be tightly adhered.

Drawings

The invention will be further explained with reference to the following figures and examples:

fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

As shown in fig. 1, a shield constructs quick-witted special type cable, including a plurality of sinle silks, the sinle silk includes conductor 1, is equipped with interior sheath in the outside of conductor 1, is equipped with reinforced braid 5 in the outside of sheath, reinforced braid 5 is aramid fiber silk braid, is equipped with outer jacket 6 in the outside of a plurality of sinle silks.

Preferably, the inner protection layer sequentially comprises a conductor shielding layer 2, an insulating layer 3 and an insulating shielding layer 4 from inside to outside. The aramid fiber yarn braided layer has the characteristics of high strength, good toughness, light weight, high stability of high temperature resistance and low temperature resistance, and good insulativity and corrosion resistance. The mechanical strength is increased, the toughness of the cable is ensured, and the anti-back-twist performance of the cable is enhanced.

Preferably, the inner sheath layer is arranged on the outer side of the conductor 1 in a three-layer co-extrusion mode. The three-layer co-extrusion can prevent external impurities from being introduced between the main insulation layer and the conductor shield and between the main insulation layer and the insulation shield, and can tightly combine all layers together to prevent accidental damage.

Preferably, the number of the wire cores is three.

Preferably, the conductor 1 is formed by twisting a plurality of tinned wire bundles. Compared with a single-core wire, the wire subjected to compound twisting has the characteristics of flexibility and mechanical strength, and can be conveniently suitable for moving the shield machine.

The above-mentioned embodiments are merely preferred embodiments of the present invention, and should not be considered as limitations of the present invention, and the protection scope of the present invention should be defined by the technical solutions described in the claims, and includes equivalent alternatives of technical features in the technical solutions described in the claims. Namely, equivalent alterations and modifications within the scope of the invention are also within the scope of the invention.
