Description

Marine cable with copper conductors with rubber insulation, PVC plastic sheath.


Manufactured in accordance with GOST 7866.2 - 76.
It is used in power and lighting networks, in control circuits, signaling and inter - device connections for alternating voltage up to 690 V with frequency up to 400 Hz or direct voltage of 1200 V; for fixed installation indoors and on the open deck, provided

 

Brand design

1. Conductor - copper, round, multi - wire; 3 class of flexibility according to GOST 22483 - section from 1 to 4 mm2, 2 class of flexibility according to GOST 22483 - section from 6 to 400 mm2.


2. Separating layer - it is allowed to apply synthetic films over current - carrying conductors (under the insulation) of cables.
3. Insulation - insulating rubber.
4. Twisting - insulated conductors of cables are twisted into a cable in concentric twists in different directions, it is allowed to twist insulated conductors in concentric twists in one direction. Insulated conductors of two - core cables with a cross - section up to 4 mm2 inclusive are allowed to be placed in parallel. Each line of cables with a conductor cross - section up to 2.5 mm2 inclusive has a counting conductor and a direction conductor.
When twisting insulated conductors into a cable, it is allowed to use a rubber cord as a filling.
5. Separating layer - one synthetic film is wound over the insulation of single - core cables and the outer layer of insulated cable cores.
6. Inner sheath - PVC compound.
