In addition to enhanced heat resistance, XLPE provides excellent dielectric strength, chemical resistance, and reduced water absorption. It is also more environmentally stable over time, maintaining flexibility and insulation integrity even after prolonged exposure to UV radiation and moisture. For critical infrastructure and outdoor installations, XLPE is often the preferred insulation choice.

Conductor Materials: Balancing Conductivity, Weight, and Cost

Copper Conductors

Copper is the gold standard for electrical conductors in 95 mm² single core cables due to its exceptional electrical conductivity—nearly 100% IACS (International Annealed Copper Standard). This ensures minimal power loss and efficient energy transmission, even under heavy loads.

In addition to superior conductivity, copper offers excellent corrosion resistance, ductility, and tensile strength. These properties make copper ideal for applications requiring long-term reliability, such as building wiring, power substations, and renewable energy systems. However, copper is heavier and more expensive than aluminum, which can be a limiting factor in large-scale or weight-sensitive installations.

Aluminum Conductors

Aluminum is a cost-effective and lightweight alternative to copper, with approximately 60% of the conductivity but only about 30% of the weight. This makes aluminum-based 95 mm² cables particularly suitable for overhead power lines, aerospace applications, automotive wiring, and large-scale utility projects where reducing structural load is critical.

However, aluminum is more prone to oxidation and requires special connectors and installation techniques to prevent loosening and overheating at termination points. Despite these challenges, when properly installed, aluminum conductors offer a reliable and economical solution for medium to high-power transmission.
