The conductors in the symmetrical cable are generally copper wires with a wire diameter of 0.25 mm to 1.4 mm. The diameter of the symmetrical cable used in the city is usually 0.4 mm to 0.9 mm; the diameter of the symmetrical cable used for long distance is usually 1.2 mm. Symmetrical cables with al...

Symmetrical cables are manufactured from pairs of twin conductors called cores within a protective jacket. In order to reduce the interference between each pair of wires, each pair of wires is made into a twisted shape, which is called twisted pair. The twisted pair is two copper wires with a diamet...
