6. The wire is passed through a 46m (150-foot) long water-filled pipe<br />

with 13 cooling stations such that by the end the cable is cooled to 50°c<br />

(120°F).<br />

7. A look inside one of the cooling stations. Just like the pipe, it is also<br />

filled with water. The wire runs through here and gets cooled in the<br />

process.<br />

8.Technician Anderson Lopez is in charge of cable production. He says,<br />

“Here at the end the wire has reached room temperature so that now it can<br />

be wound up. 5km (about 3 miles) of wire can fit on one roll.”<br />

9. The coax cable is now only half finished. The shielding is missing. This<br />

machine takes care of that: 16 rotating spindles (8 above and 8 below)<br />

create the outside braid. Technician Anderson Lopez explains, “It involves<br />

aluminum wire with a diameter of 0.6mm.”<br />

10. This is how the raw coaxial cable comes out of the machine.<br />

11. now the last step: The outer protective sheath is added to the raw<br />

coaxial cable. This process is similar to the application of the inner<br />

dielectric: The raw coaxial cable passes through this machine at a rate of<br />

50 to 120 meters/minute, or 164 to 390 feet/minute (depending on cable<br />

type), is heated to 200°c (about 390°F) and is then coated in a plastic<br />

protective jacket.<br />

12. The completed cable is once again run through a water bath to cool it<br />

off but this time it’s only 20m (65 feet) long.<br />
