Special feature: The use of four-core cables to transmit large amounts of power in a 400 Hz grid results in voltage asymmetries and larger inductive voltage losses. These unfavourable cable characteristics can be improved through the employment of seven-core cables. In this case the central core is used as a earth conductor (blue) and six cores with the same cross-section (black with imprint) stranded in a single layer around the central core. Each pair of two opposite cores is connected in parallel to a phase conductor.

Application
400 Hz cables are used to supply power to aircraft (on-board power), data processing systems, radar stations, radio stations, etc. For safety reasons, 400 Hz cables are used to connect data processing systems, radar systems and communications systems to uninterruptible power supplies. Such power supplies prevent a total failure of power and compensate for frequency and voltage fluctuations. Suitable for installation indoors, outdoors. Applications: Below floor level cable dispensers (drums), attached to jetways and retractable articulated cable carries. CE = The product is conformed with the EC Low-Voltage Directive 2006/95/EC.
