Title:
LOW-VOLTAGE CABLE WITH BUILT-IN OPTICAL FIBER, AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/093340
Kind Code:
A1
Abstract:
Disclosed is a low-voltage cable with a built-in optical fiber, the low-voltage cable comprising a temperature measurement optical fiber (1), wherein the peripheral surface of the temperature measurement optical fiber is coated with a gel (2); a corrugated copper pipe (3) is provided outside the gel (2); a copper wire (4) is spirally wound around an outer groove of the corrugated copper pipe (3); and an insulating layer (5) is wrapped around the outside of the corrugated copper pipe (3) and the copper wire (4). With a conventional low-voltage cable being internally provided with an optical fiber, the optical fiber unit is protected by means of the corrugated copper pipe (3), which overcomes the defect of the low bending performance of a conventional copper pipe, so as to meet the usage requirement for the movement and folding of the cable during the installation and use of the low-voltage cable, while also protecting the built-in optical fiber unit.
