Bus cables typically consist of the following components:
- Conductor: Made of copper or aluminum, responsible for transmitting current or signals.
- Insulation layer: Encases the conductor to prevent short circuits and signal leakage; common materials include polyethylene and polyvinyl chloride.
- Shielding layer: Composed of a metal braided mesh or foil, reducing external electromagnetic interference.
- Sheath: The outermost protective structure, providing mechanical strength and environmental resistance, such as flame-retardant or moisture-proof designs.
