How to Choose the Right Cable: Complete Technical Guide

Introduction

Selecting the right cable for your project is crucial for ensuring safety, efficiency, and longevity. This comprehensive guide will help you understand the key factors to consider when choosing cables.

Key Factors to Consider

1. Voltage Level

  • Low Voltage (0.6/1kV): Suitable for residential and light commercial applications
  • Medium Voltage (6-35kV): Industrial and distribution networks
  • High Voltage (110kV+): Power transmission lines

2. Conductor Material

Aluminum Conductors: - Lighter weight - More cost-effective - Suitable for long-distance transmission

Copper Conductors: - Better conductivity - Higher flexibility - Ideal for precision applications

3. Environmental Conditions

Consider these environmental factors:

  • Temperature range: -40°C to +90°C operating range
  • UV exposure: Use UV-resistant insulation for outdoor installations
  • Chemical exposure: Select appropriate jacket materials
  • Mechanical stress: Choose armored cables for harsh conditions

Cable Types by Application

ABC (Aerial Bundled Cable)

Perfect for overhead power distribution in residential areas.

ACSR (Aluminum Conductor Steel Reinforced)

Ideal for high-tension transmission lines.

Power Cables

Suitable for underground installation and industrial plants.

OPGW (Optical Ground Wire)

Combines power transmission with fiber optic communication.

Installation Considerations

  1. Bending Radius: Minimum 15x cable diameter
  2. Load Capacity: Calculate based on actual requirements
  3. Future Expansion: Plan for 20-30% capacity overhead
  4. Maintenance Access: Ensure easy accessibility

Conclusion

Choosing the right cable requires careful consideration of voltage level, conductor material, environmental conditions, and application requirements. At SiTong Cable, we offer expert consultation to help you select the perfect cable for your project.
