XLPE v/s PVC Insulated Cables

CABLES

This article will be useful for you as it will give complete information regarding the main differences between the XLPE and PVC cables. Both of these types are being used currently for insulating the cables and wires.

XLPE Insulated Cables

  • XLPE cables have higher current carrying capacity as it can withstand higher temperature as compared to PVC cable.
  • They usually have high overload capacity.
  • They are lighter in weight, have smaller bend radius, therefore they have lesser
    installation cost.
  • XLPE has higher short circuit rating which makes it helpful in case of failures.
  • They have lower di -electric and constant power factor .This helps in saving of power losses.

PVC Insulated Cables

  • PVC has essentially a superior fire retarding properties due to its chlorine content which makes it less risky to fire incidents.
  • PVC can be extruded, melted and re-extruded (or formed as Thermoplastic compound) whereas XLPE is a thermoset, which means it is not capable of regaining its thermal melting point to be reconfigured or re-extruded.
  • Due to these properties Thermoset (XLPE) is prone to give better results in higher temperature environments.

The main difference between PVC & XLPE is that PVC can be extruded, melted and re-extruded (or formed as Thermoplastic compound) whereas XLPE is a thermoset. This means that it is not capable of regaining its thermal melting point to be reconfigured or re-extruded. Due to these properties XLPE is prone to give better results in higher temperature environments.
Cross linking improves the elevated-temperature properties of the base polymer.Low temperature properties are improved. The impact and tensile strength, scratch resistance, and resistance to brittle fracture are enhanced in case of XLPE insulated cables.
