The system has a set of envelopes (3) made of aluminum or aluminum alloy, and sleeves (2) arranged in the form of solid insulators enclosing rigid electrical conductors (1). A coating (4) is plated on an inner face of each envelope, and a gas insulator (5) is provided inside the envelope, where radial thickness of the gas insulator is larger than thickness of each solid insulator. Insulating supports (6) support the electrical conductors. A steel envelope (8) encloses the system. |
