Common Cable Types

• Power Cables: For distributing electricity in homes and industries.
• Coaxial Cables: Used for TV and data communication.
• Fiber Optic Cables: Transmit high-speed data using light.

Applications

From powering household appliances to industrial machines and data centers, cables are everywhere.

Conclusion

Understanding the types and applications of cables helps you select the right solution for safe and efficient power transmission.
