a composite cable

Abstract

The embodiment of the invention provides a composite cable. The composite rope comprises an optical cable, a first ground plane and a second ground plane, wherein the first ground plane wraps outside the optical cable and comprises first number-preset ground wires which are surrounded to form a ring shape and wrap the optical cable, and the spaces among various first number-preset ground wires meet a first preset space value; the second ground plane wraps outside the first ground plane and comprises second number-preset ground wires which are surrounded to form the ring shape and wrap the first number-preset ground wires, and the spaces among various second number-preset ground wires meet a second preset space value; and the second preset number is larger than the first preset number. The composite cable provided by the embodiment of the invention achieves electric isolation performance based on ground wire and communication functions and meets the stress-resistant requirement of the composite cable.

Description

technical field [0001] The invention relates to the technical field of cables, and more specifically, to a composite cable. Background technique [0002] At present, in the transmission line of the power system, the optical fiber communication network is mainly laid through the OPGW (Optical Fiber Composite Overhead Ground Wire) optical cable, so as to realize the interaction of power data among the data processing equipment of the power system; the OPGW optical cable is used in the transmission line. The optical fiber communication network can realize the communication function and also have the ground wire function required by the transmission line. [0003] The inventor found in the process of realizing the present invention that: although the OPGW optical cable can have the dual functions of ground wire and communication, the electrical isolation performance of the OPGW optical cable is not high, and accidental failures are prone to occur in some power transmission field...

Problems solved by technology

[0003] The inventor found in the process of realizing the present invention that: although the OPGW optical cable can have dual functions of ground wire and communication, the electrical isolation performance of the OPGW optical cable is not high, and accidental failures are prone to occur in some power transmission fields; In the incoming system of the substation, because the electrical isolation performance of the OPGW optical cable is not high, it often occurs that the OPGW optical cable discharges the substation frame and causes a broken strand.
