coaxial cable production<br />
1. A drum containing nearly 700kg (1,500 Lbs) of copper wire in the<br />
protective cage.<br />
2. The copper wire is fed at a speed of roughly 13 meters/second (43 feet/<br />
second). The first stop is this machine which stretches the wire so that<br />
any possible production failures can be eliminated.<br />
3. The cable production control box. The speed is shown in the upper left<br />
at 12 m/s (about 40 feet/sec).<br />
4-5. The first step takes place here: making the internal dielectric spacer.<br />
The plastic granules are heated and coated around the wire passing<br />
through the machine. This process heats the wire to about 220°c (430°F).<br />
The wire first has to be cooled before anything else can be done.
