Existing Solutions for EMI Protectionin Railway

Electro-Magnetic Compatibility for Railway Cables

Compatibility with Existing Connectors & Grounding Methods







Signal Cables are shielded to :Be protected from the environment

Power Cables are shielded to :Protect the environment







Metallic Braids


Metallic Braids

Difficult to install on big lengths Apertures created by installation


Metallic Raceways


Metallic Raceways

Heavy & Big Expensive solution / component & installation


Metallic Ribbons

Very Low EMI Performances Installation in multilayers time consuming







From Tubular to Open


Construction stable whatever the length

From Changing to set EMI Results

Installation modifies the Construction


Provide ease of installation on long lengths Keep construction stable whatever the

diameter Same performance as a 65% coverage
