Abstract

The invention discloses an optical fiber composite low-voltage cable, which comprises a plurality of conductors and optical units, the conductors and optical units are twisted together, the outside of the conductors and optical units is provided with a wrapping tape, and a tearing rope is embedded in the wrapping tape , the outer side of the tape is provided with an outer sheath, the outer side of the conductor is provided with an insulating sheath, the outer side of the optical unit is provided with an optical unit sheath, and the optical unit sheath includes the following materials by weight: ethylene-acetic acid 60~80 parts of vinyl ester copolymer, 10~20 parts of linear low density polyethylene, 10~20 parts of EPDM rubber, 1~2.5 parts of vinyl triethoxysilane, didodecane thiodipropionate 1~2 parts of 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, dibutylzinc dithiocarbamate 0.5~1.5 parts, triethylhexyl phosphoric acid 1 ~2 servings. The optical unit sheath in the optical fiber composite low-voltage cable can isolate high temperature from the outside.

Description

Technical field [0001] The present invention relates to a composite cable, and more particularly to a fiber composite low voltage cable. Background technique [0002] Optical Fiber Composite Low-Voltage Cable, Optical Fiber Composite Low-Voltage Cable, OPLC) is a composite cable that combines light units in a low voltage power cable, which can carry out power information, and perform light communication transmission. Distribution network project. As one of the important cable products in the construction of smart grids, OPLC is one of the important cable products, which combines power and communication, and reduces the cost of network construction. It is one of the most cost-effective "multi-network integration" products. The current national standard specifies that the maximum temperature of the OPLC conductor does not exceed 90 degrees Celsius, but when short-circuited, the conductor is short (longest 5S) temperature can reach 250 degrees. Light units located on one side of the...
