Thermoplastic PVC cables can withstand temperatures up to how many degrees Celsius?

Explanation:
PVC insulation has a temperature rating that determines how hot the conductor may safely become. For standard thermoplastic PVC cables, the continuous operating temperature is 70°C, which is the maximum the insulation is designed to withstand without degrading. Higher ratings like 90°C exist for some specialized cables, but those use different materials or constructions. So, the typical and correct maximum for thermoplastic PVC cables is 70°C.
