Embodiment Construction
[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0033] figure 1 The self-supporting composite structure multifunctional high-voltage power cable for environment-friendly smart grid shown includes a cable core, and the cable core is formed by twisting a plurality of power cores and a communication optical cable 6; the gap between the cable cores is There is a filling layer 7 of halogen-free high flame-retardant glass fiber rope, and the outer layer of the cable core is overlapped and wrapped with a halogen-free high flame-retardant glass fiber tape around the cladding layer 8, and the halogen-free high flame-retardant glass fiber tape is wrapped around the cladding layer with a thermoplastic non-woven fabric. Halogen, low-smoke, high flame-retardant polyolefin isolation tape or polyethylene inner sheath 9, a reinforced load-bearing core 10 is arranged outside the isolation belt or inner sheath, and galvaniz...
