Signalling Cables
CONSTRUCTION
| Conductor | : | Each conductor shall consist of a solid round/stranded wire(s) of annealed high conductivity copper, smoothly drawn, nominally circular in section , uniform in quality and resistance and free from defects. |
| Insulation | : | Insulation shall be of PVC Compound conforming to requirements of Type-A compound of IS 5831:1984. Insulation color shall be as per customer specification. |
| Sheath | : | The sheath shall be of PVC Compound conforming to requirements of Type- ST1 as per IS 5831:1984. |
| Core Formation | : | The insulated cores shall be laid up together with suitable lay. The outer most layer shall have right hand lay and the successive layers shall be laid with opposite lay. A polyester tape of suitable thickness shall be helically applied normally in cables with double steel tape with suitable overlap. |
