Wiring Protection and EMC Solutions for Rolling Stock
We offer a wide range of products that meet railway rolling stock material fire safety test standards and UL standards.
We address the stringent requirements specific to railways, including flame retardancy, vibration resistance, and EMC measures.
Challenge
Are you facing any of these wiring challenges in railway rolling stock?
To ensure passenger safety, railway rolling stock wiring materials require extremely high flame retardancy and reliability. Stringent standards, different from general industrial applications, are imposed, including compliance with domestic and international fire safety test standards, durability in vibrating and bending environments, and EMC noise countermeasures.
1
Need to comply with railway rolling stock material fire safety tests and submit flame retardancy certificates
2
High-voltage insulation and anti-tracking measures for busbars and power systems
3
Wiring abrasion and disconnection due to vibration and bending during operation
4
Interference with control and communication systems due to EMC noise
5
Insulation for special areas such as vehicle connections
Application
Main application areas in railway rolling stock
EMC noise countermeasures for distribution boards and control systems
Shielded Braided Tube FLSEnhanced high-voltage insulation for busbars and power systems
Busbar Tube HOSWiring protection for vibrating and bending parts during operation
Braided Tube FLInsulation and moisture protection for metal wires and automatic control devices
3:1 Shrink Tube CCPrevention of contact and disconnection between wires due to vibration
Ring Partition RPInsulation coating for vehicle connection plates
Connection Plate Coating (Inquire Separately)
Certification
What is the Railway Rolling Stock Material Fire Safety Test?
Many compliant products in our lineup
Only highly flame-retardant materials can be used in railway rolling stock.
To prevent the spread of fire in case of an accident, railway rolling stock is mandated to use wiring materials that comply with fire safety tests. In many cases, general industrial materials are not sufficient, and the procurement of products that have passed the tests and the submission of certificates are required. Denka Electron manufactures many products that have passed railway rolling stock material fire safety tests and acquired UL standards, and we quickly provide certification documents.
Many products comply with Railway Rolling Stock Material Fire Safety Test UL VW-1 certified products available All products compliant with RoHS2 Certification documents issued quickly
