technical parameters for 1kV Heat Shrinkable Cable Accessories based on IEC 60502 standards:
| Technical Parameter | Detailed Requirements | Standard Reference |
|---|---|---|
| Rated Voltage | AC 1 kV (Um=1.2 kV) / DC 1.5 kV | IEC 60502-1:2021 |
| Insulation Material | Radiation-crosslinked polyolefin (XLPO) or EPR/HEPR, thickness compliant with IEC 60502-1 for 1.8/3kV class | IEC 60502-1:2021 |
| Conductor Compatibility | Copper or aluminum conductors, compliant with IEC 60228 Class 1/2 (cross-section: 10-1000 mm²) | IEC 60502-1:2021 |
| Shielding Requirements | Optional (copper tape/wire shielding, min. 16 mm² for ≤120 mm² conductors) | IEC 60502-1 |
| Shrink Ratio | 3:1 or 4:1 for uniform contraction | Industry norms (IEC 60502-based design) |

IEC 60502-4:2023 |
| Additional Notes Scope of Standards: IEC 60502-1 applies to cables and accessories rated 1kV (Um=1.2kV) to 30kV. 1kV accessories must meet Part 1 structural and performance criteria. Key Tests: Immersion Test: IEC 60502-4 mandates 72-hour immersion for outdoor terminations to validate sealing. Partial Discharge: Test voltage = 1.73 × U0 (rated voltage), discharge ≤10 pC. Material Selection: Heat-shrink materials must exhibit aging resistance. XLPO/EPR/HEPR insulation thickness aligns with voltage class (e.g., 2.0-3.0mm for 1.8/3kV cables). For full test procedures or specialized applications (e.g., subsea or nuclear plants), refer to other IEC 60502 series documents or national supplements (e.g., GB/T 12706). | ||
