True or False: Grounding cables with clear thermoplastic insulation become stiff at low temperatures.

Grounding cables with clear thermoplastic insulation do indeed become stiff at low temperatures. This behavior is a characteristic of many thermoplastic materials, which can lose flexibility when exposed to colder conditions. As the temperature drops, the molecular chains in the thermoplastic materials contract, leading to a loss of pliability and increased rigidity. This can affect the handling and installation of these cables in colder environments.

While the flexibility can be impacted by other factors, such as moisture exposure or the specific manufacturing processes involved, the fundamental nature of the thermoplastic material itself is a decisive factor in its performance at low temperatures. The answer reflects a general truth regarding thermoplastics, making it accurate.
