Problems solved by technology
[0003] In addition, due to the ever-changing peripheral environment, it is often necessary to add new cables, that is, to carry out secondary processing on the laying site, which not only limits the construction space, but also takes time and effort, and is inefficient. In the secondary laying of cables, there may be problems such as loose cable bundling, sagging cables between brackets, crossed cables, chaotic routing, etc., and it is necessary to avoid damage to the laid cables, reduce the service life of the cables, and bring safety hazards

The invention provides a novel pre-embedded photoelectric composite cable, which comprises an optical unit, an electric unit, a central reinforcing member, a reserved unit, and a high-temperature-resistant belting layer, a belting layer and an outer sheath which are sequentially coated outside a cable core and formed by the optical unit, the electric unit, the central reinforcing member and the reserved unit, and the reserved unit comprises a copper pipe, a steel wire rope arranged in the copper pipe and a copper pipe insulating layer arranged outside the copper pipe. The cable not only adapts to areas with complex environments, but also can be laid in the later period through the cable to meet the later-period requirements.
Description
technical field [0001] The invention belongs to the technical field of cable manufacture, and in particular relates to a novel pre-embedded photoelectric composite cable. Background technique [0002] Photoelectric composite cable is a cable with the ability to transmit electric energy and optical communication, which is composed of an insulated core and an optical transmission unit. The core part of the technology is the ultra-dense heterogeneous network, which determines that the location of the base station, one of the components of the 5G network, must exist in any area with a complex natural environment. Therefore, the characteristics of the photoelectric composite cable and the ability to adapt to complex and harsh environments Increasingly demanding. [0003] In addition, due to the ever-changing peripheral environment, it is often necessary to add new cables, that is, to carry out secondary processing on the laying site, which not only limits the construction space,...
