Contact Wire Heating

Eliminate Costly Interruptions of Revenue Service due to the effect of ice/frost accumulation on the tramline/trolley/contact wire.

Ice on the contact wire causes tramlines and light rails to lose power and in extreme cases leads to the contact wire/catenary system being brought down. Arcing caused by the presence of ice leads to excessive wear to the pantograph conductors, all leading to traffic delays and service disruption.
 
NIBE Railway Components offers the System BLUE WIRE that heats up the wire to prevent accumulation of ice.
