Efficiency will drive the future of public transportation. The constant growth of urban centers increases commute and travel times. This results in an increased need for more efficiently engineered railway solutions. The VESA system is a complementary combination of High Voltage components that are typically required for installation between the pantograph and the transformer as well as between cars within the RAIL industry.
VESA Vacuum Circuit Breaker
VESA vacuum circuit breaker (VCB) for railway electrification is the first completely electro-magnetically operated system for 25kV and 15kV vehicles. More than 1200 units on four continents, with the first unit installed over ten years ago, generate an unbeatable proven reliability and thus lead the electrical rail vehicle market into a new era.
High Voltage Power Distribution for Rail Vehicles. TE cable assemblies provide a ‘straight from the box’ solution for high voltage inter-connector cables on electric rail vehicles. Industry-leading Raychem high voltage insulation and stress control materials are combined with flexible EPR insulated cable to make assemblies that are easy to install and completely reliable in the harsh rail environment.
HV Inter-Car Jumper Cables
TE Connectivity jumper cables provide a low profile, reliable and maintenance free solution as inter-car jumpers in high voltage roof-lines and pantograph connection cables.
HV Rail Approved T- Connectors
Rail approved T-Connectors for rolling stock - Type C Interface. This T-connector family is optimized & tested specifically for the Rail market and meets EN45545-2:2013 – HL2.
OCP2 Surge Arresters for AC Networks
Bowthorpe EMP AC-type OCP2 surge arresters provide active over voltage protection that contributes directly to protecting expensive assets and improved reliability of the railway system. These are designed and tested to meet our customers’ needs, offering reliability and improved operational performance. The OCP2 are qualified as per IEC 60099-4 standards and all test reports are independently certified. It is also tested specifically for the Rail market and meets EN 45545-2 and qualified for GOST Certificate of Conformity.
HE 60 Surge Arresters for DC Networks
The HE60 surge arrester is used for the protection of DC rail networks against switching and atmospheric overvoltages. The surge arrester which has a polymeric housing and a void free construction can be used in in both DC railway systems and networks up to 4.0 kV. HE 60 surge arresters have been tested in compliance with the EN 50123-5 standard for surge arresters in DC networks for railways. Further tests have been carried out to examine the insulation withstand on the arrester housing, residual voltage, long duration current impulse and few more.
Introducing the new rail approved T-Connector. 800 A up to 42 kV optimized for Rolling Stock & High Transient applications. RSTI-68R-HT connectors, RSTI-CC-68R-HT coupling connectors & inline joints. This T-connector family is optimized & tested specifically for the Rail market and meets the new European fire & smoke norm
