Embodiment

[0020] This embodiment provides a method for manufacturing a cable, and the processing method includes the following steps:

[0021] S1, wire bundle: the wire bundle is to combine 38 original copper wires into one strand on a wire bundle machine to form a basic cable.

[0022] Specifically, the processing method of the basic cable is to first twist 19 to 30 original copper wires together to form a core wire bundle, and then twist 8 to 19 original copper wires on the core wire bundle to form an outer layer wire , the grain direction of the core wire bundle is left, and the grain direction of the outer layer wire is right.

[0023] The nominal cross-sectional area of ​​the basic cable is 0.45-0.55㎜ 2 , the pitch of the basic cables is 12-18mm.

[0024] S2, pipe stranding: the pipe stranding is to combine 12 strands of the basic cables into one strand on a stranding machine to form an intermediate product cable.

[0025] The processing method of the intermediate product cable ...

Abstract

The invention discloses a method for making a cable, which includes the following steps: S1, wire bundle: the wire bundle is to combine 38 original copper wires into one strand on a wire bundle machine to form a basic cable; S2, tube stranding: The tube stranding is to combine 12 strands of the basic cables into one strand on the stranding machine to form an intermediate product cable; S3, cage stranding: the cage stranding is to combine the 19 strands of the intermediate product cables on the cage stranding machine And into a strand to form the final product cable. The basic cable, the intermediate product cable and the final product cable are respectively formed through three steps of stranding, tube stranding and cage stranding, and each step is composed of two small steps to make the copper cable stranding more tightly In fact, the ability to withstand external forces is stronger in the end.

Description

technical field [0001] The invention relates to the technical field of cable processing, in particular to a method for making a cable. Background technique [0002] Existing cables can generally be divided into two types according to their uses, one is a communication cable used to transmit signals such as voice, data and monitoring; the other is a power cable used to transmit electric power. In the field of power cables, the quality of the cable is not only related to the material of the cable, but also has a lot to do with the processing method of the cable. Power transmission lines, because the power transmission lines need to transmit a large current intensity, the generated electromagnetic field intensity is also strong, and the laying and working environment of power cables are often relatively harsh, and the intensity that needs to be endured is very high. [0003] Existing power cables are usually made by twisting original copper wires or aluminum wires together or ...
