|---|---|---|
| Continuous operating temperature | 90°C | 70°C |
| Emergency overload temperature | 130°C | 100°C |
| Short circuit temperature | 250°C | 160°C |
| Current carrying capacity | Higher (due to higher temperature rating) | Lower |

Installation Guidelines
Preparation
-
Inspect the cable for any damage to the PVC sheath before installation
-
Store cables on clean, dry reels, protected from direct sunlight and moisture
-
Preheat the cable if ambient temperature is below 0°C – cold cable can crack the PVC sheath
Pulling and Bending
| Parameter | Value |
|---|---|
| Minimum bending radius (single core, unarmoured) | 20 × overall diameter |
| Maximum pulling tension | Approximately 15 × conductor cross-section (mm²) in Newtons |
| Sidewall pressure limit | Consult engineering datasheet for specific values |
Termination
-
Use connectors rated for aluminum – standard copper lugs can cause galvanic corrosion and loose connections
-
Apply anti-oxidant compound to conductor surfaces before termination
-
Use torque wrench to ensure proper tightening – aluminum requires more precise torque than copper
Testing After Installation
-
Perform high voltage test at 3.5kV DC for 15 minutes (per IEC 60502-1)
-
Check continuity of all conductors
-
Verify insulation resistance (minimum 100 MΩ)

A: MOQ depends on the conductor size. For standard sizes (16mm² to 240mm²), we accept orders as low as 500 meters for trial purposes.
Q: What connectors should I use for aluminum cable termination?
A: Always use connectors specifically rated for aluminum (typically tin-plated or bi-metallic lugs). Apply anti-oxidant compound and use a torque wrench for proper tightening.
Q: What is the typical lead time?
A: Typical lead time is 15–25 days after deposit confirmation, depending on order quantity and conductor size.
Q: Can I get custom printing on the cable?
A: Yes, we support OEM/ODM orders including custom printing (project name, customer logo, sequential metering, voltage marking).
