CABLES FOR HYDRO POWER PROJECTS
SVARN HYDROPOWER CABLES
Setting the standard for hydropower efficiency
Cable design is integral to optimising the efficiency and lifespan of hydropower projects.
Hydropower plants, with their complex design and geographies, demand seamless functionality, where cables play a pivotal role. They facilitate telecommunications, instrumentation, control systems, and monitoring. However, these cables face daunting challenges like temperature variations, dust, and humidity.
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 your plant.
HO7RN-8-F
SVARN HYDRO RUBBER INSULATED CABLE
Designed for versatile use in a range of environments from dry to wet, including workshops with potentially explosive 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.
COMPREHENSIVE CABLING SOLUTIONS
FOR HYDROPOWER PROJECTS
CONTROL CABLES
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 optimizing rotor RPMs.
POWER & CONTROL CABLES
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.
FIELDBUS, COAXIAL CABLES
Can Bus or Profibus cables have fixed impedance and transmit an extremely precise digital signal to control all essential PV array functions, like motors, rudder,s and hydraulic systems. Coaxial cables are usually used for on-board high frequency data transmission (communication equipment, radar, and instrumentation) and also carry video signals for surveillance cameras.
LV FIXED INSTALLATION CABLES
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.
FIBER-OPTIC CABLES
Svarn’s robust and halogen-free fibre optic cables ensure high data transmission capacity for monitoring and control in energy-dense environments, providing Electromagnetic Compatibility (EMC). These cables are exceptionally flexible and can withstand high torsion, making them suitable for demanding applications. With large cores (200 microns), connectivity is made easier, ensuring reliable performance in critical operations.
FIRE RESISTANT CABLES
In a fire emergency, onboard equipment must remain operational to aid safe evacuations. Svarn excels in innovative fire-resistant cable design 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.
ELECTRONIC AND DATA TRANSMISSION CABLES
Thermoplastic Modified (TPM) cables, with 2 to 5-core sensor multicore options, measure wind speed, temperatures, and performance parameters. Additionally, 2-core Fieldbus cables control electronic and mechanical devices alongside energy cables. Two-core Profibus cables offer speeds up to 12 Mbit/s for precise control services, and data transmission cables provide Industrial Ethernet speeds. All cables are shielded for Electromagnetic Compatibility (EMC) protection.
