Problems solved by technology
In this structure, since the size of the butterfly cable unit itself is about 2mm×3mm, and there are only one or two optical fibers in it, it is very uneconomical. In addition, the cable core needs to be completely dissected during connection. Therefore, for The unused parts cause great damage; moreover, electricity and light are transmitted in the same twisted body, and the power unit is relatively close to the butterfly cable unit, so the power due to load heating will greatly hinder the transmission of optical signals

The invention belongs to the technical field of the electric power and cables, and particularly relates to a photovoltaic composite cable for a power system. The photovoltaic composite cable comprises a bushing body, a protection layer and a jacket layer, and the photovoltaic composite cable is characterized in that a light transmission element is arranged in the bushing body, and the outer circumference of the bushing body is provided with an opening and a protection bar; a symmetric axis of the opening passes through the center of the bushing body, a storage chamber which is communicated with the opening is arranged below the opening, the storage chamber is not communicated with a cavity for storing the light transmission element, two adjacent storage chambers are not communicated with each other, the storage chambers are distributed in the bushing body, each storage chamber is provided with an opening inner side and an opening outer side, and the width of each storage chamber is gradually increased from any opening inner side to the center of the storage chamber along the symmetric axis of the opening; a power transmission unit is arranged in each storage chamber. The photovoltaic composite cable has the main beneficial effects that branches are convenient to introduce, no electric transmission unit twisting device is needed, few production procedures are needed, the outer diameter of the composite cable is small, and the cost is low.
Description
technical field [0001] The invention belongs to the field of electric power and cable technology, and in particular relates to a photoelectric composite cable used in a power system. Background technique [0002] With the promotion of the integration of three networks / four networks, a large number of photoelectric composite cables are needed in the domestic power system. This kind of photoelectric composite cable can be used in the access of power towers to power users, mainly divided into towers to electric meters and electric meters to Subscriber unit; it can also be used between the community transformer unit and the tower; it can also be used on instruments and equipment that need remote power supply; and so on. [0003] For this reason, a large amount of research and development and use of photoelectric composite cables have been carried out at home and abroad. The authorized announcement number is CN201717056U, and the patent name is: A photoelectric composite cable fo...
