Problems solved by technology

For the metal-clad cable produced by the above-mentioned production method, the copper tape forms a helical seam line on the surface of the metal-clad cable after winding. The seam line is long and has a gap. The corrosion resistance life of the copper tape in the atmospheric environment is short, which seriously affects the performance of the entire metal-clad cable

Embodiment Construction

[0017] The production method of a metal-clad cable according to the present invention will be further described in detail through specific examples below.

[0018] Such as figure 1 Shown, a kind of production method of metal-clad cable comprises the following steps:

[0019] a. Unwinding: put the core cable wire and the metal strip on the core cable unwinder 1 and the metal strip unwinder 2 respectively for unwinding;

[0020] b. Coating: The core cable conductor is continuously released by the method of curling the metal strip into a tube and continuous longitudinal wrapping. The metal strip is continuously curled and coated outside the core cable conductor. a metal strip forming a metal tube with a longitudinal butt seam;

[0021] c. Continuous online longitudinal seam welding: use the welding head 3 to carry out online continuous longitudinal seam welding on the longitudinal butt joints by welding, and argon arc welding or plasma welding can be used;

[0022] d. Stretchi...

Abstract

The invention relates to a production method for a metal coated cable. The production method comprises the following steps: a step of unreeling, namely unreeling a core cable wire and a metal band respectively, a step of coating, namely adopting a method of curling the metal band to be a tube and continuously and lengthways wrapping to enable the core cable wire to be continuously led out, wherein the metal band is continuously and curly wrapped outside the core cable wire, after the curly wrapping is finished, a metal tube is formed on the surface of the cable wire, and a lengthways butt joint is reserved, a step of continuously welding the lengthways joint on line, namely adopting a welding method to carry out continuous on-line lengthways joint welding on the lengthways butt joint, a step of stretching, namely carrying out hole shrinkage stretching on the welded metal coated cable to enable the diameter of the cable to reach a desired size and enable the outer metal tube to be closely attached to the inner cable, a step of washing, namely carrying out degreasing washing on the stretched metal coated cable, a step of on-line annealing, namely carrying out the annealing on the metal coated cable, and a step of compound winding rolling, namely carrying out compound winding rolling on the annealed metal coated cable. The production method is suitable for manufacturing a railway penetration ground wire or a shield cable.

Description

technical field [0001] The invention relates to a production method of a metal clad cable, the metal clad cable is mainly used as a high-speed rail ground wire. Background technique [0002] Due to its special use occasions, the high-speed rail ground wire is not only required to have superior electrical conductivity, but also must ensure the safety and reliability of the cable, as well as anti-corrosion in the atmospheric environment. The currently used metal-clad cables are usually produced by a winding and covering method, and a layer of copper tape is wound and coated on the outside of the core cable in a spiral winding manner. For the metal-clad cable produced by the above-mentioned production method, a spiral seam line is formed on the surface of the metal-clad cable after the copper tape is wound. The seam line is long and has a gap. The anti-corrosion life of the copper tape in the atmospheric environment is short, which seriously affects the performance of the enti...
