Optical cable

Abstract

The present invented photoelectricity cable is also known as electric light cable, which is a transmission medium-wire cable capable of same way transmitting electric energy and electrical signal. The metallic conduction wire core of Said wire cable is parallel with optical fiber of cable, optical fiber longitudinal located inner or outer of reinforced member, metallic conduction wire core and optical fiber covered with insulation protection layer and integrated by external sheath layer, photoelectricity cable cross section presenting dumb-bell shape. Fiber-optic reinforced member can be plastics frame or steel wire and metal longitudinal binding band. Photoelectricity cable can meet the requirement of less than 10 kw electric energy transference and optical fiber network communication.

Description

technical field [0001] The present invention relates to optical and electrical transmission media, that is, optical cables for transmitting optical signals and cables for transmitting electrical energy. Background technique [0002] In the power system, power cables of different voltage levels are used to transmit or distribute high-power (below 10KV or 35KV) electric energy. Compared with the overhead bare wire, the power cable has less interference from the external climate environment and high power supply reliability; the larger capacitance is conducive to improving the power factor of the power system; it has an insulating layer, a sheath, and an outer sheath, which can withstand mechanical It has the advantages of external force or pulling force, safety, and not easy to be damaged, but it can only transmit electric energy. As an optical signal transmission medium, the optical fiber must be made into an optical cable with a complex structure in...

Problems solved by technology

Compared with the overhead bare wire, the power cable has less interference from the external climate environment and high power supply reliability; the larger capacitance is conducive to improving the power factor of the power system; it has an insulating layer, a sheath, and an outer sheath, which can withstand mechanical External force or pulling force, safe, not easy to damage, etc., but it can only transmit electric energy

As an optical signal transmission medium, the optical fiber must be made into a complex optical cable in order to ensure long-term use under various laying conditions and in various environments.

In today's society, it is often necessary to transmit electrical energy and optical signals at the same time and in the same direction to meet the needs of power and information transmission and measurement. Therefore, power cables and optical cables need to be laid separately, which greatly increases engineering difficulty and construction investment.
