Understanding PUR Cable

Understanding PUR Cable

1. Introduction to PUR Cables

• What is PUR (Polyurethane) cable?

  • PUR cable is Polyurethane cable, it is a cable with Polyurethane as the cable sheath
  • VDE code: 11Y.

• Why are PUR cables suitable for industrial and harsh environments?

  • PUR cables have the best Weather Performance compared to other materials such as PVC PE XLPE, which allows them to work in low temperatures and outdoor environments. In addition, its Corrosion Behavior is also very good, which allows it to be used in chemical plants.

2. Main Characteristics of PUR Cables
