Description

Technical Field

[0001] This utility model belongs to the field of power optical cable technology, and specifically relates to a power optical cable with a protective structure. Background Technology

[0002] Power optical cables are various composite cables and special optical cables used in power systems to both transmit power and communicate information. A power optical cable is a communication line that uses a certain number of optical fibers arranged in a certain way to form a cable core, which is covered with a sheath, and some are also covered with an outer protective layer, to realize the transmission of optical signals.

[0003] However, existing power fiber optic cables are generally protected by an outer sheath made of polyethylene material. Polyethylene is a polymer material with disadvantages such as short lifespan, poor resistance to bending, and poor resistance to sunlight. These disadvantages are mainly manifested in the following ways:

[0004] Poor heat resistance: Polyethylene has a low heat distortion temperature and is prone to softening and deformation at high temperatures.

[0005] Insufficient mechanical strength: Low tensile strength and hardness, unsuitable for load-bearing structures.

[0006] Polyethylene is easily deformed and has low surface hardness, making it prone to scratches.

[0007] Prone to aging and decomposition: Long-term exposure to sunlight or high temperatures will cause oxidation and discoloration, resulting in decreased performance.

[0008] When used in power optical cables, the cables may be damaged when subjected to compression or impact. In addition, existing power optical cables generally contain multiple optical cable conductors, and these conductors are closely connected. Therefore, when they are subjected to impact or compression, the optical fibers and the inside of the cable will also be damaged, thus reducing their service life. Utility Model Content

[0011] An inner support ring is provided on the outside of the support core, an aramid wrapping layer is provided on the outside of the inner support ring, a polyethylene protective tube layer is provided on the outside of the aramid wrapping layer, and a wear-resistant layer is provided on the outside of the protective tube layer.

[0012] Preferably, the support core is made of a multi-directional three-dimensional polymer.

[0013] Optionally, the inner support ring includes an inner ring and an outer ring, the inner ring and the outer ring being arranged coaxially, and further includes a plurality of V-shaped supports evenly distributed along the center between the inner ring and the outer ring.

[0014] Beneficial effects:
