CEDASPE CBB-OA, Typical 12 kV Oil / Air cable box bushing

 

The Oil / Air range of cable box bushings are designed in accordance to EN 50336 and comply with IEC 60137. A range of bushings are available up to 36 kV-4000 A. If higher voltages or currents are required resin impregnated condenser bushings can be offered to meet customized requirements.

It is important for the transformer designer to use cable box bushings as they have been specifically designed for use within indoor applications, this ensures that the electrical characteristics (specifically creepage distances) are based on their working conditions.
