Application
INTER-AEROFLEX 400Hz 3*70+3*12+6*(4*1) PUR is a low load-loss electrical power supply cables for aeronautical use (400 Hz Systems for dynamic or static applications). The cable design allows all GPU's manufacturer and all airport facilities to rely only on one single type of cable for all applications, including
- Underground pits
- Passenger boarding bridges
- Mobile generators
- Cable coils
- Crocodiles
- Static application, e.g. aircraft hangars
This cable can be operated under extreme environmental conditions and high mechanical stress.
The power is transmitted via 3 special designed and patented phase conductors and a neutral conductor which is divided into 3 single conductors laying in the gaps between the phase conductors. 6 quads of 4 twisted control wires are also placed in-between the gaps for support functions. Especial designed for the use in airports or public areas and buildings where special requirements regarding fire protection and security are requested.
