Design- Conductor
Copper wire, 0.9 or 1.4 mm nominal diameter - Insulation
Solid polyethylene - Quadding
Four insulated conductors are twisted together to form a quad - Stranding
Conductors are helically stranded in concentric layers. - Core wrapping
Plastic tape(s) with overlapping - Electrostatic shield
One layer of helically applied copper wires or one corrugated copper tape - Intermediate sheath
Low density polyethylene - Electromagnetic shield
Two helically applied steel tapes - Outer sheath
Low density polyethylene
