6. The wire is passed through a 46m (150-foot) long water-filled pipe
with 13 cooling stations such that by the end the cable is cooled to 50°C
7. A look inside one of the cooling stations. Just like the pipe, it is also
filled with water. The wire runs through here and gets cooled in the
8.Technician Anderson Lopez is in charge of Cable Production. He says,
“Here at the end the wire has reached room temperature so that now it can
be wound up. 5km (about 3 miles) of wire can fit on one roll.”
9. The coax cable is now only half finished. The shielding is missing. This
machine takes care of that: 16 rotating spindles (8 above and 8 below)
create the outside braid. Technician Anderson Lopez explains, “It involves
aluminum wire with a diameter of 0.6mm.”
10. This is how the raw coaxial cable comes out of the machine.
11. Now the last step: The outer protective sheath is added to the raw
coaxial cable. This process is similar to the application of the inner
dielectric: The raw coaxial cable passes through this machine at a rate of
50 to 120 meters/minute, or 164 to 390 feet/minute (depending on cable
type), is heated to 200°C (about 390°F) and is then coated in a plastic
protective jacket.
12. The completed cable is once again run through a water bath to cool it
off but this time it’s only 20m (65 feet) long.
