Low voltage cables with copper conductor , PVC sheath and XLPE insulation.
In the above structure, copper is used as the main conductor of the cable. The type of insulation used are Crosslinkable polyethylene (so-called XLPE) material and the materials of sheath used are polyvinyl chloride or PVC.
Crosslinking or networking means creating transverse connections (crosslinks) between molecular chains, which improves the mechanical properties, thermal resistance and electrical properties of insulation.
It is possible to use filler materials in multi-core cables to round the outer surface of the cable, which is not mandatory in the standard.
The conductors of the above cables are produced as solid core (so-called RE), Circular starnded (RM), shaped stranded (sector -SM-) or as compact conductors (RM/V).
0.6/1 KV is the most used of this group of products. The routine technical specifications of this type of cables are as follows:
