In modern power systems and industrial projects, choosing the right cable is crucial. When it comes to high-temperature resistant, high-performance, and stable cables, AC90 cable has become the preferred choice for many engineers and companies. But with so many specifications and sizes, you may wonder: what size AC90 cable is right for your project?
This article will provide a detailed guide on AC90 cable sizes, selection tips, and installation precautions, while also introducing our company's professional advantages in supplying AC90 cables.
What is AC90 Cable?
AC90 cable is a high-temperature resistant, corrosion-resistant, and well-insulated power cable, widely used in construction, factory equipment, lighting systems, and power transmission. Its key features include:
- High-temperature tolerance: Can operate stably at up to 90°C
- Excellent insulation: Minimizes leakage risk and ensures system safety
- Durability: Resistant to abrasion and corrosion, suitable for various installation environments
- Versatility: Available in single-core, multi-core, and shielded designs
Understanding AC90 cable performance is the first step to selecting the right size.
AC90 Cable Size Specifications
AC90 cable sizes are mainly determined by conductor cross-section and outer diameter, with different projects requiring different current capacities and installation environments. Common specifications include:
| Conductor Cross-Section (mm²) | Conductor Diameter (mm) | Cable Outer Diameter (mm) | Application Notes |
|---|---|---|---|
| 1.5 | 1.38 | 4.0 | Small lighting & low-power devices |
| 2.5 | 1.78 | 5.0 | Residential & light industrial use |
| 4 | 2.26 | 6.0 | Medium-power distribution lines |
| 6 | 2.76 | 7.5 | Industrial equipment & high-power loads |
| 10 | 3.57 | 10.0 | High-power machinery & large-scale projects |
Note: Specific dimensions may vary slightly depending on the manufacturer. Always verify with your project requirements before final selection.
Key Points for Selecting AC90 Cable Size
When choosing AC90 cables, consider these factors:
- Current-carrying capacity: Ensure the cable can handle the project's current continuously
- Installation environment: Indoor, conduit, tray, or underground installations affect diameter and flexibility requirements
- Safety margin: A 10–20% load margin is recommended for long-term safety
- Standards compliance: Ensure compliance with local electrical codes and national standards
Proper sizing ensures both system safety and optimal equipment performance.
AC90 Cable Installation Precautions
Proper installation is equally important:
- Bending radius: Maintain the manufacturer's recommended minimum to avoid conductor damage
- Terminal matching: Use appropriate terminals and connectors for stable electrical connections
- Installation method: Ensure proper ventilation and avoid excessive compression
- Protection and labeling: Mark cables clearly and protect them during construction and operation
These details help reduce maintenance costs and extend the cable's service life.
