Pressurized Air Cables for 245 kV, 4000 A: The new product for 245 kV, 4000 A covers demanding high-voltage applications up to 1600 MW transmission capacity in a single system.
Hivoduct offers pressurized air cables for efficient and sustainable electric energy transmission at medium voltage and high voltage levels. This new technology is based on pressurized air as main insulation gas combined with a patented flange connecction. These cables are suitable for a wide application range in medium- and high voltage, with rated currents 200 A up to 4000 A and interfaces to overhead lines, Gas-insulated Switchgear, Transformers, and cables.
Unique technical characteristics
The base design of pressurized air cables based on the patented ring flange system and using pressurized air as main insulation gas offers a unique combination of electrical, mechanical, and thermal characteristics, which are advantageous in many applications. Specifically, the large conductor cross section (> 2000 mm2) enables high rated currents and lowest losses during operation. The corresponding roller system allows compact laying into microtunnels or protection tubes. The metallic enclosure offers best fire protection, grounding, internal arc fault protection and reduces the EMV exposure. Additional advantages are the tiny bending radius, no cable joints needed and the reduced reactive power requirement.
Expanding the portfolio up to 245 kV
The existing pressurized air cable products cover the medium voltage (12 kV to 52 kV) as well as the high voltage (72 kV to 145 kV) range. All products offer rated currents up to 3000 A.
The new pressurized air cable product for 245 kV, 4000 A enables transmission applications in a typical high voltage range while maintaining the great product characteristics.
