HV Inter-Car Jumper Cable

TE Connectivity's high-voltage jumper cables provide a low-profile, reliable and maintenance-free solution as inter-car jumpers in high-voltage rooflines and pantograph connection cables.

The combination of industry-leading Raychem high voltage insulation materials and an engineering plastic strength spine gives a design that is highly flexible over a wide temperature range and is resistant to the rigours of the high voltage rail environment. HVJL  jumper cables are used as part of the high voltage roof-line on high speed trains and EMUs and are highly flexible to take up any lateral, longitudinal and vertical movements. Jumpers can be attached to support insulators or directly to self-supporting terminations on the high voltage cables. 

Product Features

  • 15 / 25 kV roof-line inter-car jumper cables optimised for use in the rail environment
  • Dual wall insulated to reduce the risk of flashover and proof against accidental contact
  • Optional push on boots for insulation of connections
  • Completely sealed to prevent water ingress and ice blocking
  • Low profile giving improved clearances and minimising wind resistance
  • Coiled form allows large flexing range with minimum space usage
  • Flexible across a wide operating temperature range
  • Dimensions customisable for individual applications
  • Impact resistant
  • Low weight
  • Maintenance free minimising total life-cycle costs

About

The low profile of these cables result in vertical space saving, design freedom, low drag, usability in a fully sealed high voltage roofline system, and low maintenance.

  • Fire and smoke specification EN45545
  • Suitable for use at 15 and 25 kV AC
  • The wear plates and donuts are made from low friction material to minimize maintenance costs.

About

The loop jumper is particularly suited to applications where movement is required along all three axes but size and profile is not critical.

  • Suitable for use between 750 V DC and 25 kV AC 
  • Different conductor sizes are available giving current carrying capacity up to 2000 A

About

The U jumper is ideal where movements are relatively small and are primarily in the plane of the jumper.

  • Suitable for use between 750 V DC and 25 kV AC
  • Different conductor sizes are available giving a current carrying capacity up to 2000 A.

Custom Design Service

We offer a complete design service (2D or 3D CAD models can be provided) to create a tailor made jumper cable for each application. The train designer needs to provide:

  • Distance between car ends
  • Range of possible movements in service
  • Frequency of movements in service
  • Current carrying requirements

Testing

Our HVJL jumper cables have been subjected to a range of qualification tests including: 

  • Whole-life flex testing
  • High Voltage withstand tests
  • Current cycling thermal tests
  • Shock and vibration
  • Mechanical cycling to extremes
  • Low temperature flexing

 

Test reports are available on request.
