XLPE insulated cable vs PVC insulated cable - Which one to choose
PVC (Polyvinyl chloride) and XLPE (Cross-linked polyethylene) are types of plastic used as insulation in power cables. Both have their advantages and drawbacks due to varying properties. To choose one of these for a specific situation, one must keep in view following comparison:
XLPE is clearly superior to PVC in almost all aspects expect for the economy factor.
| XLPE insulated cable | PVC insulated cable | |
| Chemical Structure | Themoset | Thermoplastic |
| Max temperature rating | 90 | 70 |
| Min temperature rating | -90 | -15 |
| Dielectric Strength (KV/mm) | 550 | 350 |
| Price | Lower | |
| Durability | Higher | |
| Fire retarding property | Better | |
| Short circuit rating | Higher | |
| Flexibility | Better | |
| Weight | Lighter | |
| Bending radius | Less | |
| Current Carrying Capacity | Higher | |
| Corrosion resistance | Better | |
| Moisture Penetration Resistance | Better | |
| Oil Resistance | Better | |
| Solvent Resistance | Better | |
| Acid Resistance | Better | |
| Alkali Resistance | Better |
