Intelligent electrical network fiber composite prefabricated branch cable and manufacture method thereof

Abstract

The invention relates to an intelligent electrical network fiber composite prefabricated branch cable and a manufacture method thereof. The cable in the invention comprises a fiber composite main cable, a fiber composite branch line cable and a prefabricated branch combiner. The fiber composite main cable comprises a conductor, an insulating layer, a semiclosed U type optical cable, a filling layer and a sheath. The semiclosed U type optical cable comprises a plurality of fibers, a U type sleeve pipe, a polyester bend and a sheath. The fibers can be led out from an opening of the U type sleeve pipe to reach the fiber composite branch line cable. According to the cable and the method in the invention, optical cable composite is protected in the cable, mechanical strength is increased, siteconstruction cost is greatly reduced, a site construction period and time are substantially reduced, site construction personnel and equipment are reduced, a requirement of construction personnel technology is lowered, and restriction of a construction site by spatial and environmental conditions is not existed.

Description

technical field [0001] The invention relates to a power and optical fiber composite transmission cable, in particular to a smart grid optical fiber composite prefabricated branch cable and a manufacturing method thereof. Background technique [0002] The smart grid can solve problems such as precise energy supply, power demand side management, free grid access, multi-power source interaction, and decentralized energy storage. It not only serves the large grid, but also serves our power end users. It may greatly change our future life. Optical fiber composite cable is the "blood" and "controlling nerve" of smart grid operation. The State Grid is vigorously promoting smart grid, establishing smart communities, smart cities, and smart factories. The application of optical fiber composite cables will gradually become widespread.

AI Technical Summary

Problems solved by technology

[0003] At present, there are two construction schemes for smart grid fiber optic composite cables used in high-rise buildings such as office buildings and residential areas. One is the general power distribution to the underground power distribution room of each building Optical fiber composite cables are used, and the optical cables and cables are divided into two cables from the underground power distribution room of each building to the floor; One fiber composite cable is placed on each floor (multiple fiber composite cables are placed in a building), and then distributed to each floor from this position, so the current fiber composite cables either cannot be directly composited into the home, or the laying scheme is more complicated
