What kind of materials is typically used in the structure of line hose?

Line hose is primarily designed for providing insulation on electrical power lines and other high-voltage applications, and rubber is traditionally used for this purpose due to its excellent insulating properties. Rubber is both flexible and durable, allowing it to maintain its integrity under various environmental conditions, which is crucial for outdoor use on power lines.

In addition to its insulating capabilities, rubber provides sufficient grip and resilience, reducing the risk of wear and tear, as well as the chance of electrical arcing. Its ability to conform to various shapes and sizes of equipment further enhances its functionality in ensuring safety and protection for those working with or around high-voltage systems.

The other materials listed may possess certain valuable characteristics; however, they do not provide the same level of insulation and flexibility that rubber does in this specific application.
