Product Description
The special filling strip for optoelectronic composite submarine cables is a filling material designed specifically for optoelectronic composite submarine cables, which plays a crucial role in the cable formation process. The following is a detailed introduction to the special filling strip for optoelectronic composite submarine cables:
1. Basic characteristics
Material composition:
The filling strip for optoelectronic composite submarine cables is usually made of PE (polyethylene) or composite PE as the substrate, and may add other materials such as rubber powder. It is plasticized by a single screw extruder, then made into a strip shape through a specific extrusion mold, and finally cooled and shaped. This material combination gives the filling strip excellent physical properties and chemical stability.
Shape design:
The shape design of the filling strip is diverse, some of which are part of a sector, with three vertices as arcs, and the two sides of the sector are also made into arcs, with a hole in the middle of the sector; Some may adopt other shapes, such as inverted W-shaped or hollow dovetail shaped, which are designed to better adapt to the structure of submarine cables and meet specific engineering requirements.
Performance advantages:
The special filling strip for optoelectronic composite submarine cables has the advantages of easy use, round filling, strong support, and good protection for fiber positioning. It can effectively locate and protect fiber optic units, avoiding damage caused by compression during cable formation, while making the entire submarine cable round and enhancing the stability and reliability of the cable formation.
2. Application advantages
Improve submarine cable performance:
The use of filling strips can significantly improve the overall performance of optoelectronic composite submarine cables, including key indicators such as roundness, compressive strength, and tensile strength. These performance improvements help submarine cables maintain stable transmission performance and service life in complex marine environments.
Reduce maintenance costs:
High quality filling strips can reduce the failure rate of submarine cables during use, thereby lowering maintenance costs. Meanwhile, due to its excellent corrosion resistance and high-voltage electrical insulation, it can also reduce the risk of cable damage caused by environmental factors.
3. Market and Development
With the widespread application of optoelectronic composite submarine cables in underwater communication, ocean observation, offshore wind power and other fields, the market demand for specialized filling strips for optoelectronic composite submarine cables is also constantly increasing. In the future, with the continuous advancement of materials science and processing technology, the performance and quality of filling strips will be further improved and optimized to meet the higher requirements of submarine cable manufacturing.
