Multi-strand special conductor stranding process of numerical control cage type stranding machine

Abstract

The invention discloses a multi-strand special conductor stranding process of a numerical control cage type stranding machine. The multi-strand special conductor stranding process comprises the stepsof S1, pre-stranding multi-strand tinned soft copper stranded wires, special fiber silk and special fiber silk filling yarns to form an inner conductor; and S2, weaving a tinned copper wire outer conductor outside the inner conductor to form a multi-strand special conductor cable. The stranding process has the beneficial effects that the multi-strand tinned soft copper stranded wires, the specialfiber silk, the special fiber silk filling yarns and the tinned copper wire outer conductor are stranded to form the cable, so that the tensile property of the cable is improved, the flexibility of the cable is improved, the laying space is reduced, and the special requirement for reciprocating movement is met; in addition, integral forming is adopted, so that the electrical performance of a product is improved and the structure is round and stable; and furthermore, the cable is not easy to crack and spall and long in service life.

Description

technical field [0001] The invention relates to the technical field of cable processing, in particular to a multi-strand special conductor stranding process of a numerically controlled cage type stranding machine. Background technique [0002] With the continuous acceleration of my country's economic construction at this stage, the demand for power supply and communication continues to increase, and the demand for cables has increased significantly, especially in recent years. The internal power supply and the underwater transmission lines across the river and sea. In power lines, the proportion of cables is gradually increasing. [0003] Power cables are cable products used to transmit and distribute high-power electric energy in the main lines of power systems. However, in the prior art, due to cracks and bursts in the plastic protective layer, it is particularly easy to cause grounding faults, Short-circuit faults, disconnection faults or flashover faults, once the cable...

[0003] Power cables are cable products used to transmit and distribute high-power electric energy in the main lines of power systems. However, in the prior art, due to cracks and bursts in the plastic protective layer, it is particularly easy to cause grounding faults, Short-circuit faults, disconnection faults or flashover faults, once the cable has a problem, it will cause a lot of losses, and it will also bring great difficulties to maintenance and line inspection
