What problem does using a popsicle eliminate in a stranded aluminum conductor?

Using a popsicle can help eliminate cold flow problems in stranded aluminum conductors. Cold flow refers to the deformation of materials under prolonged mechanical stress or load at lower temperatures. Aluminum is particularly susceptible to cold flow, which can lead to increased resistance at the connection points and affect the long-term reliability of the electrical connection.

The popsicle can provide a more uniform grip and support on the conductor strands, preventing them from moving or settling unevenly over time. This improvement in mechanical stability helps maintain better electrical contact and prevents issues related to loose connections, which can arise due to cold flow, ensuring efficient transmission of electricity.

Other options, while they may have some relevance in different electrical contexts, do not directly address the primary benefit that the popsicle provides in terms of preventing the long-term deterioration of a connection caused by cold flow.
