Drawing upon our expertise in cabling solutions for critical infrastructures, Svarn offers bespoke cabling and harness solutions perfectly suited for hydroelectric projects. Leveraging years of experience, our offerings guarantee tangible advantages such as enhanced operational reliability, efficiency, and safety for our planet.
Designed for versatile use in a range of environments from dry to wet, including workshops with potentially unsuitable atmospheres, this cable can withstand immersion in fresh water up to depths of 10 meters. However, it is not intended for underwater power transmission or installation in waterways where mechanical damage could pose a hazard. This cable is well-suited for connections subject to moderate mechanical stresses, such as workshop equipment, large boilers, portable motors, and generators. With a voltage rating of up to 1KV, it is also suitable for fixed installations along floors or shelving, as well as for rotor connections to lifting equipment motors.
Svarn flexible shielded cables, ranging from 2 to 100 cores, efficiently transport energy, ranging from 300 volts to 1kV, along with low-frequency signals essential for controlling motor drives or generators. These cables play a crucial role in tasks such as breaking, positioning, or optimizing rotor RPMs. Special sheathing is available for ultra-low temperatures, while smaller cables are halogen-free. Our torsion and oil-resistant cables are designed to last for 20 years and more.
Ensuring continuous functionality during emergencies is critical in hydropower plants. Svarn leads in fire-resistant cable technology, crafting control and power cables specifically for safety systems like emergency lighting, fire detection, and door-opening mechanisms. These cables maintain electrical circuit integrity for a defined duration post-fire, enhancing safety for both personnel and the plant itself. Svarn’s fire-resistant cables are instrumental in safeguarding lives and infrastructure within hydropower facilities.
In hydropower plants, Can-Bus or Profibus cables ensure precise control over functions such as motor operation, rudder adjustment, and hydraulic systems with their fixed impedance and accurate digital signal transmission. Coaxial cables handle high-frequency data transmission for communication equipment, and instrumentation onboard, while also delivering video signals for surveillance cameras.
Svarn manufactures LV silicone cables designed specifically for hydropower plants, ideal for connecting generators to transformers. These cables are engineered to withstand extreme heat up to 120°C and are available in a Low-Smoke Zero-Halogen (LSZH) version for added safety.
To ensure high data transmission capacity for monitoring and control, Svarn’s rugged, halogen-free fibre-optic cables offer Electromagnetic Compatibility (EMC) in energy-dense areas. They are very flexible and can handle high torsion. Large cores (200 microns) make connectivity easier.
Svarn unarmoured power and control cables are used for wiring fixed installations not subject to mechanical risks, while armoured cables are recommended for areas where enhanced mechanical protection and electrical screening (Electromagnetic Compatibility) is required. The highly flexible range of cables are recommended for installations and connections in narrow spaces where an optimal bending radius is required. The sectoral conductors of multicore cables provide further space and weight savings on the cable trays.
These cables (up to 1KV) reliably transmit energy produced in the generator to the transformer. They come in Low-Smoke Zero-Halogen (LSZH) versions and are also oil, abrasion, UV and Ozone resistant. Before supply, Svarn rigorously tests these cables for lifetime durability, adhering to strict movement and torsion standards.
Svarn provides hydro OEMs with LV aluminum cables. These cables, whether single or multicore, offer EMC screening. Compared to copper, aluminum single cores are larger yet weigh half as much, making them cost-effective and easier to handle during installation.
Thermoplastic Modified (TPM) 2 to 5-core sensor multicore and multipair cables measure water speed, temperatures, and performance parameters, while 2-core Fieldbus cables are used in parallel with energy cables to digitally control all electronic and mechanical devices. 2-core Profibus cables deliver up to 12 Mbit/sec for complex control services; and data transmission cables offer Industrial Ethernet speed. Moreover, all cables are shielded for EMC protection.
