Background

In recent years, with the rapid development of power grid construction in China, power optical fiber units for power information transmission and control have been rapidly developed, and for example, power optical fiber units such as an overhead ground wire (OPGW), a metal-free self-supporting power optical cable (ADSS), and an optical power cable (OPPC) have been widely used for long-distance power transmission lines and urban overhead lines. The optical fiber unit composite submarine cable crossing rivers, lakes and seas, the submarine photoelectric composite cable used for supplying power to an offshore oil platform, the optical fiber unit composite power cable used for connecting wind power generation equipment and a transformer substation and the like, wherein the power cables have a common characteristic that the power cables contain optical fiber units which can be used for power communication and control instrument equipment, and the optical fiber unit composite submarine cable is used for transmitting electric energy and also used as an information carrier. The cable is particularly used for underwater optical fiber unit composite cables, and the optical fiber unit and the power cable are composited together, so that the production and manufacturing cost of equipment is saved, a large amount of submarine space resources and construction cost are saved, and the cable has good social and economic benefits.

In recent years, however, the photoelectric composite cable is increasingly applied to power transmission and power grid construction in China and even in various countries around the world. The optical fiber unit composite cable must contain the optical fiber unit, and the optical unit containing metal is easy to generate loss and heat under the action of an electric field of the power cable, so that the transmission performance and the service life of the cable and the optical cable are influenced to a certain extent. And because the common non-metal optical unit has potential difference with a cable structure remote part at the periphery thereof, the induced voltage in the metal element in the optical fiber unit is too high to easily cause the breakdown of a protective layer thereof, thereby not only influencing the service life of the optical fiber unit, but also having unsafe factors on personnel and equipment.
