Lorünser Austria products

Lorünser specializes in developing bespoke solutions for switchgear connections, optimizing for both reliability and security in power supply systems. Serving voltage ranges from 66 to over 1000 kilovolts AC or DC, their products are ideal for outdoor substation applications, where the stakes include significant outage costs. The choice of material is critical for Lorünser, utilizing primary aluminium subjected to T6 heat treatment to ensure resilience and durability. Their switchgear for high-voltage applications, like the 150 kV range, caters to smaller power projects and cost-sensitive markets, focusing on ease of installation. In the extra-high voltage sector, their products support 245 and 420 kV applications, featuring over 20,000 items, including adaptable clamps designed to prevent welding. For ultra-high voltage systems up to 500 kV, specifically crafted for environments such as Peru at high altitudes, their solutions counter the insulating challenges posed by reduced air density, mitigating discharges and corona effects.

Lorünser offers a comprehensive range of hoisting and hauling pulleys designed to meet diverse operational needs, from simple cable pulleys to custom-engineered solutions. Their production process employs advanced CAD and FEM methodologies, ensuring optimal performance and reliability. The pulleys are primarily cast using permanent mould casting, yielding products with superior mechanical properties and precise dimensional accuracy. These pulleys can be fabricated from materials such as cast aluminium, wrought aluminium alloy, or steel, and weigh from a few grams to over 60 kilograms. Additionally, Lorünser provides companion parts, manufactured according to original blueprints archived for consistency. Special attention is given to the development of bearings and axles, offering maintenance-free options or relubrication-friendly designs. The pulleys feature protection from dust and water, further enhanced by advanced insert rings available in rubber, plastic, or Robalon, catering to various operational demands and ensuring the integrity of the cable and pulley structure.

High-voltage direct-current (HVDC) transmission is a key technology for enhancing the efficiency and stability of power networks, especially in response to growing energy demands and the integration of renewable energy sources. HVDC systems are known for their ability to transmit electricity over extensive distances with lower energy losses, making them more efficient than traditional alternating current (AC) systems. Lorünser has been at the forefront of HVDC technology since the 1980s, providing innovative connection technologies to enhance power transmission efficiency. Their solutions are vital for long-distance power transport projects like the Champa-Kurukshetra, enabling energy transfer over 1400 kilometers in India. The company offers a comprehensive range of components for HVDC systems, including valve hall equipment and connection technology. Their products are designed for flexibility and adaptability, capable of accommodating construction site variations, thus ensuring reliability and efficiency.
