Sheathing materials for sheathed wires are generally plastic, rubber, or metal.
Detailed explanations are as follows:
Plastic Materials: Plastic is the most common sheathing material for sheathed wires. This material has good insulation properties, abrasion resistance, and corrosion resistance. It also resists ultraviolet rays, moisture, and other harmful factors in the external environment, thus protecting the internal wires from damage. Furthermore, plastic materials are relatively lightweight and easy to process and install.
Rubber Materials: In certain specific applications, such as those requiring higher flexibility and abrasion resistance, rubber is also used as a sheathing material for sheathed wires. Rubber has good elasticity and water resistance, protecting the wires from physical damage and chemical corrosion. It is often used for wire protection in outdoor or harsh environments.
Metal Materials: In applications requiring higher levels of protection, such as explosion-proof or military applications, metal materials may also be used as sheathing materials. Metal provides excellent protection against external impacts, high temperatures, and other extreme conditions. However, metal-sheathed wires are relatively heavy, more expensive, and may affect the flexibility of the wire.
