2 Application
The cables are designed for connection between traffic control centers and equipment shelters along the trackside. The cables are specially designed to give good induction protection (R.F=0.21 at inductive voltage 100V/km) and are suitable for installation in high speed railway lines electrifi ed at 25KV ac.
