Webster-Wilkinson Porcelain Bushings
en Bushings
EN rated porcelain bushings manufactured by Webster-Wilkinson are standardised via CENELEC and designed to comply with current EN Standard requirements.
EN 50386 rated bushings range features a plastic under oil arrangement to give enhanced anti-rotation properties and negates the need for additional gaskets.
The air-side arrangement overcomes UV damage of gaskets – normally associated with the DIN range of bushings.
The range rated EN 50180 has been designed to replace the DIN Standard range of bushings over time.
