The materials used in the core and insulation of wires and cables greatly affect their performance. Here are some of the most commonly used materials:
The most common conductor material due to its excellent conductivity and durability. Copper is widely used in both power and communication cables.
Although less conductive than copper, aluminum is lighter and cheaper, making it ideal for overhead power lines where weight is a concern.
A popular insulation material, PVC is flame-retardant, durable, and cost-effective. It is commonly used in household wiring and low-voltage applications.
Known for its flexibility and resistance to harsh environments, rubber insulation is used in cables exposed to extreme weather or mechanical stress, such as mining and industrial cables.
This material provides superior heat resistance and mechanical strength, making it ideal for high-voltage and underground cables.
