tính năng
- The copper properties must be in conformity with CEI 60028 norms.
- The strength member must conferee the adequate mechanical resistance to the traction effort indicated in section 4.
- The sheath material must be black color with 2% up to 3% of the black carbon content uniformly distributed
- The cable is formed by two isolated conductors (identified by colors as referred) and twisted, with an adequate step-twisting to obtain the electrical and transmission characteristics required that could not exceed 100m
- To avoid the contact between the conductor’s isolation and the sheath, the pair is wrapped up by a polyester tape, polypropylene or equivalent material, helicoidally or longitudinally applied, with an overlap minimum of 20% of its width.
- The maximum outer diameter of the delivery cable, determined in accordance with the section 2.2.3 of CEI 60189-1, must be 5,5mm.
