Ensuring reliable cable joints at high-temperatures
In hot climates and industrial environments, high temperatures can put a lot of stress on medium voltage cable joints. From accelerated material aging to increased electrical resistance, heat poses a real threat to the performance and safety of underground energy compounds. Lovink offers a robust solution with innovative technology that guarantees reliable, long-lasting performance – even when the temperature rises.
Impact of high temperatures on cable joints
Rising ambient temperatures have a major impact on the service life and performance of medium-voltage connections:
- Increased electrical resistance: Higher temperatures create more resistance in conductors such as copper and aluminum, leading to energy loss and risk of overheating.
- Insulation Degradation: Material degradation: Plastics and rubbers can lose their properties at an accelerated rate at high temperatures, making insulation less effective or moisture sealing failing.
- Thermal expansion and contraction: Temperature fluctuations cause mechanical stresses, with a risk of cracks or failure of the joint body.
- Accelerated aging: Prolonged exposure to heat accelerates the aging process of cable materials, which reduces reliability.
