Abstract

The invention discloses a high-load heat-resistant composite cable, which includes several conductors and optical units, the conductors and optical units are twisted together, and a wrapping tape is arranged on the outside of the conductors and the light unit, and a tearing cable is embedded in the wrapping tape An outer sheath is provided on the outer side of the tape, an insulating sheath is provided on the outer side of the conductor, an optical unit sheath is provided on the outer side of the optical unit, and the optical unit sheath includes the following materials by weight: ethylene- 60~80 parts of vinyl acetate copolymer, 10~20 parts of linear low density polyethylene, 10~20 parts of EPDM rubber, 1~2.5 parts of vinyl triethoxysilane, didodecyl thiodipropionate 1~2 parts of alkyl ester, 0.5~2 parts of silicone masterbatch, 2~5 parts of lead oxide powder, 3~6 parts of ethoxylated trimethylolpropane triacrylate, N,N,N',N' ‑tetrakis[4‑(dibutylamino)phenyl]‑1,4‑phenylenediamine hexafluoroantimonate 1~3 parts, diphenylguanidine 0.5~1.5 parts, sodium lauryl sulfate 1~2 parts. The optical unit sheath in the high-load heat-resistant composite cable can isolate high temperature from the outside.

Description

technical field [0001] The invention relates to a composite cable, in particular to a high-load heat-resistant composite cable. Background technique [0002] Optical Fiber Composite Low-voltage Cable OPLC (Optical Fiber Composite Low-voltage Cable, OPLC) is a composite cable that combines an optical unit in a low-voltage power cable, which can not only transmit power information, but also perform optical communication transmission. It is suitable for low-voltage Distribution network engineering. As one of the important cable products in the construction of smart grid, OPLC integrates the functions of power and communication and reduces the cost of network construction. It is currently one of the most cost-effective "multi-network integration" products. The existing national standard stipulates that the maximum temperature of the OPLC conductor during normal operation shall not exceed 90 degrees Celsius, but in the event of a short circuit, the temperature of the conductor m...
