1. Wire: annealed copper
wire.
2. Isolation: special solid
polyethylene
3. Group: sprended wires or
pairs
4. Sprending: elementary units from
3õ0.9 to 12õ0.9 and from 3õ2õ0.9 to 12õ2õ0.9. Cable core is made by units
sprending.
5. Hydrophobic compound:
inter-wire space is filled by special hydrophobic compound, which provides
longitudinal hermetizaion of cable core.
6.
Polyester isolation: insolative polyester tape.
7. Sheath: Light-stabilized polyethylene,
stable to climate influences.
