The insulation layer of communication cables is a core component ensuring stable signal transmission and extending cable lifespan. Polyolefins, with their excellent comprehensive properties, have become the preferred insulation material for communication cables and are widely used in various fixed-lay communication lines. The core advantage of polyolefin-insulated wires lies in their superior electrical properties. Their low dielectric constant and low dielectric loss effectively reduce signal crosstalk and transmission loss, ensuring clear and stable communication signals. This meets the high signal transmission quality requirements of communication cables, making them particularly suitable for telephone networks and broadband access. Simultaneously, polyolefins have high insulation resistance and stable insulation performance, effectively preventing conductor short circuits and ensuring the safe operation of communication lines.
Secondly, polyolefins possess excellent environmental adaptability and durability. They are resistant to aging and corrosion, and can withstand a wide temperature range of -30℃ to 70℃, allowing for long-term use in complex environments such as outdoors and underground. They are not easily corroded by moisture, acids, or alkalis. Furthermore, their good flexibility facilitates bending and laying, reducing the difficulty of construction scenarios such as pipelines, overhead lines, and direct burial, and improving construction efficiency. In addition, polyolefin materials are non-toxic and environmentally friendly, releasing no harmful gases when burned, meeting the green and environmentally friendly requirements of modern communication engineering. Their low density and light weight also reduce the overall weight of cables, lowering transportation and laying costs.
Compared to other insulation materials, polyolefins offer abundant raw materials, convenient processing, and a higher cost-performance ratio, meeting the bulk demand of large-scale communication projects.
