Optical cable and coaxial optical cable

Abstract

The invention provides an optical cable comprising a cable core and an outer sheath. The cable core comprises an optical unit, phase lines and a lead; each phase line comprises a phase line conductor and a first insulating layer coating the phase line conductor; the lead is of a hollow tubular structure, and the optical unit and the phase lines are located in the hollow portion of the lead which is a null line or ground line. The invention further provides a coaxial optical cable comprising a coaxial cable core and an outer sheath. The coaxial cable core comprises an optical unit, one or multiple coaxial phase lines and a lead in sequence from inside to outside, each phase line comprises a phase line conductor and a first insulating layer coating the outer side of the phase line, and the lead is a zero line or ground line. The optical cable and the coaxial optical cable have the advantages that a structure of coating the phase lines inside with the zero lines or ground lines is adopted, when the insulating layers are aged or a line is overloaded, electric leakage of the phase lines and fire hazards are avoided, and safety of a power supply system is guaranteed.

Description

technical field [0001] The invention relates to cable technology, in particular to a high-safety optical cable and coaxial optical cable. Background technique [0002] Optical power cable (OPC) is an integrated transmission medium that organically combines metal wires and optical fibers to transmit electric energy and optical information at the same time, on the same road, and in the same direction. The role of the network. Most of the existing optical cables on the market use a structure in which the insulated power core and the optical unit are twisted together in parallel or in layers, and then covered with a protective sheath. This structure has poor safety and is prone to leakage when the insulation of the power core is aging or overloaded. It may even cause a fire. Contents of the invention [0003] In order to solve the above technical problems and propose a more secure optical cable, the present invention adopts the following technical solutions: [0004] The pr...
