N2XYRY, CU/PVC/PVC/STA/PVC
Low voltage cables with copper conductor , XLPE insulation and PVC sheath with Wire Armour.
In the above structure, aluminum is used as the main conductor of the cable. The type of insulation used are Cross-linkable polyethylene (so-called XLPE) material and the type of inner cover and sheath used are polyvinyl chloride or PVC materials. The cable armour is made of galvanized steel or aluminum.
Crosslinking or networking means creating transverse connections (crosslinks) between molecular chains, which improves the mechanical properties, thermal resistance and electrical properties of insulation.
The use of armour to increase the mechanical strength of the cable to prevent external mechanical pressures, stresses and shocks to protect it. Depending on the type of voltage used (usually DC) often the armor is made of aluminum in single core cables.
In the above cables, the armour of the armoured cables are of wire type and are placed in a helix form on the inner cover.
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:
