The heatproof properties of DC cable 4mm come from the PVC sheath. PVC is a thermoplastic material that has a high melting point. This means that it can withstand high temperatures without melting or deforming. The PVC sheath also helps to protect the copper conductor from damage caused by sunlight, moisture, and other environmental factors
