FIELD: electrical engineering.
SUBSTANCE: cable contains optic fibre, a heat-conductive polymer layer enclosing the optic fibre and copper conductors laid in an external radial position relative to the heat-conductive polymer layer. The grounding cable is designed so that to enable its underground laying and may be commented to the common ground of an electric grounding system.
EFFECT: optic fibres protection against cable temperature increase; prevention of hydrogen accumulation close to optic fibre; mechanic protection of the cable.
