Wire drawing machine in the cable industry
wire drawing is an essential process in the cable industry for producing the conductive, strengthening and supporting wires inside all types of power, data and specialty cables.
Wire drawing machines are commonly used in the cable industry to manufacture different types of cables. Here are some details on how they are utilized:
Power cables - Aluminum and copper wires are drawn to various gauges and strand configurations to make power transmission and distribution cables.
Electrical wiring cables - Copper wire is drawn to specified diameters to produce the inner conductors for electrical wiring cables used in buildings and infrastructure.
Network cables - Smaller gauge copper wires are drawn for making the four twisted pair conductors in Ethernet patch cables and other network cabling.
Coaxial cables - Copper clad steel wire is drawn for the inner conductor of coaxial cables used for cable TV and computer networks.
Fiber optic cables - Wire drawing is used to make the steel strengthening members that surround and protect the optical fibers inside fiber cables.
Wire rope - Steel wires are drawn, twisted and braided to make strong wire ropes and steel cables for applications like elevators and cranes.
The key considerations in wire drawing for cables include conductivity, strength, flexibility and uniformity of the drawn wire.
Multi-wire drawing machines that can draw multiple wires simultaneously are commonly used for efficiency and consistency in cable production.
Quality control after drawing involves testing wire diameter, tensile strength, elongation and surface flaws. The drawn wires are then insulated and twisted into cables.
