Extruded HVAC cables are insulated with cross-linked polyethylene (XLPE) and manufactured in a triple extrusion process, where semiconducting layers and the insulation layer are extruded in one step. XLPE features low relative permittivity, a very low power loss factor and high dielectric strength. ABB’s HVAC cables support integration of renewable power to the existing AC grid as well as provide a grid extension to “single-points”, such as offshore wind or oil and gas installations.
ABB has a tradition of developing record-breaking innovations with reliable results for complex demands. Since ABB pioneered the HVAC field by delivering the world’s first extruded HVAC connection in 1973, the company has gained an extensive amount of experience and launched a number of innovations, such as dynamic cable technology.
- ABB delivered the world’s first extruded HVAC submarine cable, the 145 kV Sweden-Åland, in 1973
- ABB was first to launch a dynamic power-from-shore HVAC cable system, Gjöa, in 2007
- ABB launched the world’s first three-core 420 kV, Lillebaelt, in 2013
- In 2015, ABB delivered the world’s longest HVAC cable, Martin Linge, an 162 km extruded three-core submarine cable
