3. Twisting

The insulated cable cores are twisted into a layer, each layer has a counting pair, the insulated cores of which differ in color from each other and from the rest of the cores, the color of the insulation of which must be the same.

4. Inner filling (belt insulation)

(A)KVKShp, (A)KVKShp — made of PVC plastic compound or applied by winding or longitudinally with tapes made of polyvinyl chloride plastic compound.

5. Screen

For cables (A)KVVP (A)KPvVG made of two copper tapes or copper foil, or aluminum foil with overlap, copper wire must be laid along the aluminum foil.

6. Armor

for cables (A)KVBbShv, (A)KVBShv, (A)KPvBbShv, (A)KPvBShv, (A)KVBShp, (A)KPvBShp — made of two galvanized steel tapes;
for cables (A)KVKShv, (A)KPvKShv, (A)KVKShp, (A)KPvKShp — made of galvanized steel wires;
for cables (A)KVKaShv, (A)KPvKaShv, (A)KVKaShp, (A)KPvKaShp — made of aluminum wires or aluminum alloy wires.

7. Sheath

Made of polyvinyl chloride plastic compound (v) or 3 polyethylene (p).

Application

Cables are intended for laying indoors, in canals, tunnels, in aggressive environments, in the absence of mechanical impacts on the cable. Laying in the ground (trenches) is allowed, providing protection of cables at the points of exit to the surface. Fire hazard class according to GOST 31565-2012 O1.8.2.5.4
