Application:

Tunnel; Tidal flow

 

Problem:

Replacement of a hard-wired on-road lighting system which had reached the end of its serviceable life and had issues caused by water ingress and corrosion.

 

Solution:

The issues of the existing system are caused by characteristics of wired systems, which can be avoided by using an inductive-powered system. Especially electrical joints in wiring was prone to problems caused by ingress of road surface water.
