ARRANGEMENT
INNERCONDUCTOR:copper or tinned copper wire.
INSULATION: low-densitypolyethylene. ForРК 75-3-32А, SAT-50 and RG-6 - polyethylene foam; for other models - solid.
OUTERCONDUCTOR:aluminoflex and tinned copper wires over insulation for SAT-50 and RG-6 models. Aluminoflex is laid lengthwise over insulation with separator by aluminum side to the outside of the cable. Tinned copper wire braiding is laid over aluminoflex.
Tinned copper wire braiding is laid over the insulation of the models: РК 75-3-32А, РК 75-4-11, РК 75-4-12, РК 75-4-15, РК 75-4-16, РК 75-4-11А, РК 75-4-12А, РК 75-4-15А, РК 75-4-16А, РК 75-4-11АИТ, РК 75-4-15АИТ.
SHEATH:light-stabilizedpolyethylene or PVC compound.
