0.6/1KV-Heat Shrinkable Cable Accessories

technical parameters for 1kV Heat Shrinkable Cable Accessories based on IEC 60502 standards:

Technical Parameters Table

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)
Electrical Performance	- Power frequency withstand voltage: 6.5 kV (1 min) - Partial discharge: ≤10 pC (at 1.73U0)	IEC 60502-4:2023
Mechanical Performance	- Bending radius ≥12× cable OD (post-installation) - Tensile strength ≥10 MPa (sheath)	IEC 60502-1
Environmental Resistance	- Operating temperature: -40°C to +110°C - Short-circuit tolerance: 250°C (5 sec)	IEC 60502-1
Waterproof & Sealing	Built-in hot-melt adhesive layer passing immersion test (72 hours, no leakage)	IEC 60502-4:2023
Flame Retardancy	Compliant with UL 224 VW-1 or IEC 60332-1 vertical flame test	IEC 60332
Chemical Resistance	Resistant to oil, acids, alkalis, and UV (UV stability ≥1000 hours)	IEC 60502-1 (material criteria)
Test Requirements	- Thermal cycling test (3 cycles, -40°C to +110°C) - DC withstand voltage (4U0, 15 min)	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).
