Description

Photoelectric composite cable

Technical field

The invention relates to a cable and belongs to the technical field of cables.

Background technique

In the northern alpine and western highland areas, the winter temperature is very low, and the lowest temperature can reach below -40 °C, which is especially important to ensure the normal transmission and use of electricity and communication. At present, in these alpine regions, it is commonly used to transmit cold-resistant power cables for transmitting electricity and communication cables for communicating or transmitting information. To realize both transmission of electricity and communication and transmission of information, it is necessary to lay cold-resistant power cables and cold-resistant communication cables at the same time. It not only increases the manufacturing cost, but also increases the cost of the cold-resistant cable and cold-resistant cable.

Therefore, those skilled in the art are working to develop an optoelectronic composite cable.

Summary of the invention

In view of the above drawbacks of the prior art, the technical problem to be solved by the present invention is to provide an optoelectric composite cable.

To achieve the above object, the present invention provides an optoelectric composite cable comprising a cable core and an optical cable, the cable core comprising a conductor and an insulating layer covering the outer surface of the conductor, characterized in that the cable core and the optical cable They are all disposed in the tape, and the cable core has at least two sets; the other parts in the tape are provided with a filler.

The cable core and the optical cable in the package of the present invention may have multiple groups, such as four groups, six groups or more groups, but a technical solution in which the number of cable cores is three groups may also be adopted. The center of the cable core continuously forms an equilateral triangle. When you have more groups, you can form a normal polygon, or a regular polygon. The invention is designed as an equilateral triangle or a regular polygon, which can make the cable core symmetrical, regular in shape and roundness, thereby ensuring the roundness of the whole cable, and the roundness is good to the electrical performance and physical properties of the cable. The impact of wear resistance is small.

The cable core of the present invention may be circular or other shapes, such as a conductor of a cable having a cross section of a fan or a portion of a circular annulus, in which case the entire cable core may be in the shape of a sector or a fan-like shape. . When the voltage level is 1kV or below, the cable conductor adopts other shapes such as fan shape and tile shape. After the conductor is pressed, the outer diameter of the cable is smaller than the circular shape. Without affecting the performance of the cable, the sheath material and the auxiliary material are The amount will be reduced and the cost will be further reduced.

In the above various solutions, the optical cable is preferably not located at the inner core of the range enclosed by each of the optical cable cores. The fiber optic cable is not located at the center of the cable core because on the one hand, the cable is easily squeezed by the cable core during the cable forming process, causing wire breakage. On the other hand, the center is not conducive to the terminal lead-out and wiring of the cable. .

In particular, the cable is also located between the straight sides of the sector.

Further, a gap is provided at the center of each sector, and the optical cable passes through the gap.

Separately or simultaneously, a gap is provided at an outer corner of at least one of the adjacent two sectors, through which the cable passes.

In order to further improve the stability of the cable under lower temperature conditions, the outer surface of the tape (5) is coated with a cold-resistant sheath layer.

The filling material of the invention can be selected from polypropylene filling rope, and the filling material can also be made of cold-resistant PVC filling strip, cold-resistant PE filling strip, rock wool rope, glass fiber rope, etc. The reason why the polypropylene filling rope is selected is not only because the cold resistance can be achieved. The environmental requirements, and the polypropylene filled rope material is softer than the filler strip, the protection effect on the optical cable is better, the price is cheaper than other fillers, which is beneficial to reduce the cost, and the strip filler also makes the invention easy to process. Features.

The invention has the advantages that the invention can effectively transmit power and transmit signals in a low temperature environment, and has high reliability, and is convenient for processing, and greatly reduces manufacturing and construction costs.
