Q. Where are SWA-PVC cables typically used?
A. Suitable for:
Underground direct burial (with drainage)
Industrial plants with mechanical stress
Hazardous environments (e.g., chemical exposure)
Q. How does steel wire armour enhance cable performance?
A. Mechanical protection: Resists crushing, rodent damage, and impact.
Grounding: Acts as an earth continuity conductor in some designs
Q. What are the temperature limits for SWA-PVC cables?
A. Operating range: -15°C to +70°C (PVC insulation)
Max conductor temperature: 70°C under continuous load
Q. Are SWA-PVC cables flame-retardant?
A. Standard versions comply with IEC 60332-1 (flame propagation test). For higher requirements, choose LSZH (Low Smoke Zero Halogen) variant
Q.. How to calculate bending radius during installation?
A. Minimum bending radius = 12× cable diameter to avoid armour deformation
Q.. Can SWA-PVC cables be installed in wet conditions?
A. Yes, provided the outer sheath is intact. For submerged use, ensure IP68-rated joints and anti-corrosion armour
Q. What standards apply to SWA-PVC cables?
A. International: IEC 60502-1
Regional: BS 5467 (UK), UL 4 (US)
