Application
They are used in the connection and distribution networks of the telephone switchboards, subscribers distribution networks and signal and control circuits. They are installed either in trenches, PVC or concrete conduits or buried directly in the soil. |
Construction
1. | Inner Conductor | Electrolytic mono annealed copper, (TS EN 60228, Class 1) |
2. | Insulation | Foam (KP) or Solid (P) Polyethylene, (TS3930, BS 6234 03 C) 2258 TS Cable colors to be appropriate.(Table 1) |
3. | Lay-Up | Twisting is performed for star quadruple (D) twisted cores as star-quadruples up to 10 pairs, or 5 quadruples (1) group after 10 pairs or 10 group twisting (1) package and fixed with moisture free PES tape with dielectric feature. The groups and packages are tagged with color threads. |
4. | Inner Sheath | Low (LD) or middle (MD) density polythene (ASTM D 1248); HFFR (TS EN 50290-2-27)** |
5. | Screen | Both sides PE film coated Aleminium(A) foil |
6. | Outer Sheath | Low (LD) or middle (MD) density polythene (ASTM D 1248); RAL 9005 Black HFFR (TS EN 50290-2-27) RAL 7001 Grey |
