Control cables not spreading combustion KVVGEzng(A)

CONSTRUCTION <ol> <li>conductive core - single-wire round, 1 class according to GOST 22483 made of soft copper (nominal cross-section from 0,75 to 6,00 mm2) wire.</li> <li>insulation of cores is made of polyvinylchloride plasticate.</li> <li>Core - insulated cable cores twisted by twisting.</li> <li>Separating layer (sheath) - made of polyvinylchloride plastic of reduced flammability with filling the gaps between the cores.</li> <li>shield - in the form of aluminium foil wrapping with overlapping, providing the screen continuity at permissible bending radii of cables. A tinned copper wire is laid longitudinally under the screen.</li> <li>The sheath is made of polyvinylchloride plasticate of reduced flammability.</li> </ol>Cables are designed for transmission and distribution of electrical energy and electrical signals in stationary electrical installations that require cable sealing at entry, at alternating voltage up to 660 V with frequency up to 100 Hz or direct voltage up to 1000 V.
