Product Detail

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:

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.

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.

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.

Frequently Asked Questions (FAQ)

Q1 What primary materials are used in special filling strips for submarine cables?

They are primarily manufactured using PE (polyethylene) or composite PE as the base substrate, often formulated with additives such as rubber powder, and produced via single-screw extrusion for superior chemical and physical stability.

Q2 What shapes and profiles are available for optoelectronic filling strips?

Common profile designs include sector shapes with arc vertices and center holes, inverted W-shapes, and hollow dovetail structures configured to match specific cable internal geometry and engineering requirements.

Q3 How do filling strips protect optical fibers during cable formation?

They offer precise positioning channels and cushioning support, effectively preventing optical fiber units from being crushed or damaged by lateral compression during the cable stranding and laying processes.

Q4 How does the filling strip contribute to reducing long-term maintenance costs?

By enhancing cable roundness, compressive resistance, high-voltage electrical insulation, and anti-corrosion properties, the filling strip reduces failure rates under harsh marine environments, significantly lowering overall maintenance costs.

Q5 Are non-standard dimensions and custom specifications supported?

Yes. In addition to standard models such as 8.7/10KV (3*185) and 26/35KV (3*300, 3*400), customized dimensions, opening diameters, and tailored geometric profiles are fully supported based on project specifications.

Q6 In which fields are optoelectronic composite submarine cables typically deployed?

They are widely utilized across underwater communication infrastructure, ocean observation sensor networks, offshore wind farm transmission, and cross-sea power connection grids.
