Embodiment Construction
[0014] Such as figure 1 As shown, a smart grid optical fiber composite low-voltage cable of the present invention includes an outer sheath 8, and the outer sheath 8 is provided with a power cable, an optical cable 1 and a radio frequency cable 6, and the power cable, the optical cable 1 and the radio frequency cable 6 are arranged in an orderly manner Stranded. The optical cable 1 is wrapped with a longitudinal aluminum-plastic composite tape, and the aluminum-plastic composite tape is wrapped with a water-blocking tape, which can maximize the horizontal and vertical water-blocking effects of the optical cable 1, thereby ensuring the design performance and service life of the cable. The power cable includes a conductor 2 and an irradiated cross-linked polyethylene insulating layer 3 wrapped around the conductor 2, the power cable, the optical cable 1 and the radio frequency cable 6 are covered with a non-hygroscopic wrapping tape 7, and the outer sheath 8 is wrapped Outside t...

The invention discloses an optical fiber composite low-voltage cable for a smart grid, comprising an outer sheath, wherein the outer sheath is internally provided with a power cable, an optical cable and a radio-frequency cable which are mutually twisted, the optical cable is wrapped with a longitudinal Al-plastic composite tape, the Al-plastic composite tape is wrapped with a waterproof tape, the power cable comprises a conductor and an irradiation cross-linked polyethylene insulating layer wrapped outside the conductor, the power cable, the optical cable and the radio-frequency cable are coated with a non-hygroscopic wrapping tape, the outer sheath is wrapped outside the non-hygroscopic wrapping tape, and a non-hygroscopic filler is filled between the non-hygroscopic wrapping tape as well as the power cable, the optical cable and the radio-frequency cable. The invention has the beneficial effects that the comprehensive cost is low, the stability of product performance is guaranteed, the electrical energy loss in an application process is reduced, the electrical energy can be more stably transmitted, and the electrical property of the cable is guaranteed, thus the electrical energy can be effectively transmitted.
Description
technical field [0001] The invention relates to a cable, in particular to a smart grid optical fiber composite low-voltage cable. Background technique [0002] With the deepening of the smart grid construction, the country will continue to increase the promotion of the integration of the four networks on the basis of the integration of the three networks. Another important market segment. Smart grid construction puts forward new requirements for traditional optical cables and power transmission. It needs to integrate optical fiber communication, signal transmission and power transmission to meet the needs of smart grid informatization, automation, and interaction. It provides safe and reliable guarantee for the smart grid, and provides technical support for the construction and implementation of the Internet of Things. However, there is no cable that can meet this requirement in the market at present. Contents of the invention [0003] In order to solve the above techni...
