Cable design is integral to optimising the efficiency and lifespan of wind energy projects. At Svarn, our focus is on manufacturing cables that minimise power loss, maximise transmission efficiency, and withstand extreme weather conditions, whether deployed in onshore or offshore wind farms. Our dedication to product excellence is upheld by our advanced in-house production and testing facilities, enabling us to provide customers with a diverse range of high quality products conforming to international standards.
Copper cables can be single or multicore, featuring EMC screening. In contrast, single-core aluminum cables are larger but weigh half as much, making them more cost-effective and easier to handle and install, especially in tall towers. Svarn provides low-voltage aluminum cables to major wind energy OEMs.
In a fire emergency, onboard equipment must remain operational to aid safe evacuations. Svarn excels in innovative fire-resistant cables designed for control and power applications, vital for safety systems like emergency lighting, fire detection, and door-opening mechanisms. These cables ensure electrical circuit integrity for a specified period post-fire onset, enhancing safety in wind farms and protecting lives and infrastructure from fire risks.
Can-Bus or Profibus cables offer fixed impedance for precise digital signal transmission, controlling essential functions like motors and hydraulics. Coaxial cables handle high-frequency data transmission onboard, including video signals for surveillance cameras. Optical fibers transmit information over long distances at high speeds, and are immune to electromagnetic interference from power cables or machinery.
Unarmoured cables suit fixed installations without mechanical risk, while armoured cables are recommended for areas needing enhanced mechanical protection and EMC screening. Svarn’s highly flexible cables are ideal for narrow spaces with tight bending requirements. Multicore cables with sectoral conductors offer additional space and weight savings on cable trays.
LAN cables facilitate secure and high-speed data transmission for solar irrigation via RJ45 connectivity. Depending on performance needs, LAN cables are available in various categories such as Cat 6 and Cat 6A, tailored for demanding communication systems. To meet mechanical and EMC challenges, LAN cables feature designs with tinned copper braid, SF/UTP, or S/FTP shielding. They are offered in configurations of 4 pairs or 2×4 pairs to help minimise installation expenses.
Flexible shielded cables with 2 to 100 cores are versatile components used in various applications, including carrying energy and low-frequency signals to control motor drives or generators in wind turbines. These cables play a crucial role in transmitting power and control signals, enabling functions such as braking, positioning, and optimising rotor RPMs.
