Temperature changes can have a significant impact on electrical cable joints. Over time, exposure to extreme heat or cold can cause the materials used in the joint to expand or contract, which might weaken the connection. Electrical cable joints are designed to withstand a certain range of temperatures, but consistent exposure to temperature fluctuations can affect their integrity. To prevent any adverse effects, it's essential to check the insulation around the joint for any signs of deterioration caused by temperature stress. If the insulation has become brittle or cracked, it may be necessary to replace it to ensure the cable joint remains effective.
