Ensuring cable splice reliability in high-temperature environments
In hot climates and industrial settings, elevated temperatures can put medium voltage cable splices and joints under serious stress. From accelerated material degradation to increased electrical resistance. Heat poses a real threat to the performance and safety of underground power connections. Lovink offers a robust solution with its innovative technology – designed to maintain reliable, long-lasting performance even when temperatures soar.
The impact of high-temperature on cable splices
High ambient temperatures can significantly affect the performance and longevity of medium voltage cable splices and joints. As temperatures rise, several issues may arise:
- Increased electrical resistance: higher temperatures cause the resistance of conductors like copper and aluminum to increase, leading to greater energy losses and potential overheating.
- Insulation degradation: materials suchs as PVC and XLPE can soften or degrade at elevated temperatures, compromising the insulation’s effectiveness and increasing the risk of short circuits.
- Thermal expansion and contraction: fluctuating temperatures can cause materials to expand and contract, leading to mechanical stresses that may result in cracks or failures in the splice.
- Accelerated aging: prolonged exposure to high temperatures can accelerate the aging process of cable materials, reducing their lifespan and reliability.
Our solution: Innovative MV splices
Lovink addresses these high-temperature challenges with our innovative medium voltage cable splices:
- Fluid silicone insulation: LoviSil® utilizes fluid silicone that remains flexible and encapsulates every part of the splice, minimizing the risk of partial discharge and ensuring consistent performance.
- Enhanced thermal performance: The dielectric constant of LoviSil® is nearly identical to that of polymeric cables, providing a homogeneous electric field and reducing the effects of thermal expansion.
- Proven durability: With over 40 years of field experience, LoviSil® splices have demonstrated exceptional reliability in various environmental conditions, including high-temperature environments.
