HV Ringmain

In the 2015 Ryebridge was proud to receive a third consecutive RoSpa Gold Award for its work on the HV Ringmain at London Luton Airport, where in partnership with Bowers Electrical Ltd they updated the 50+ year old High Voltage infrastructure that feeds the airfield.

Ryebridge installed 11km of HV cable around a live airport environment having only one minor cable strike throughout the whole job. It installed a new substation, high voltage cable diversion/installation and Thrust Boring under taxiways and runway.

To reduce damage to the airports runway and taxiways, Ryebridge implemented horizontal directional drilling (HDD), a steerable trenchless method of installing underground pipes, conduits and cables in a shallow arc along a prescribed bore path using a surface-launched drilling rig, with minimal impact on the surrounding area, something that Ryebridge always strives to do.
