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.  The grounding of the T-connector is improved, sealed, shock & vibration resistant and disconnectable.

There is no need for a second grounding lead and ensures improved ease of installation once the cable assembly has been made and tested before installation in the vehicle.  

Tested against specific Rail standards


  • Shock & vibration standards. (IEC 61373: 2010)
  • Smoke & Fire norm. (EN45545-2:2013 – HL2)
  • High Voltage Switching Transients Accelerated Life Test, a special TE Connectivity in-house developed test method to simulate the typical transient effects generated in rolling stock roofline applications.
  • Silicone rubber insulation offering reliable operation over an extremely wide range of operating temperatures.
  • Environmentally sealed/shock & vibration resistant connector fitted to the grounding lead enabling disconnection from the cable screen for installation and/or test purposes.

Main Features

  •  The insulation of the T-connector is made of a highly modified silicone rubber characterized by high tracking resistance, elongation at break and non-flammability.
  • A thin walled screen is permanently bonded onto the insulation that protects the connection system against accidental contact.
  • The screened connector need not be removed for over sheath testing.
  • The earth lead can be easily disconnected via the single pole AMP Superseal 1.5 SERIES sealed connector.
  • The overall dimensions are designed to take up minimum space.
  • Easily accessible rear plug with capacitive test point for determining whether the
    circuit is energized. A conductive cap protects this test point.
  • The screened cable connector exceeds CENELEC HD 629.1 S2 requirements,
    which includes BS; VDE and other international specifications.
  • Design is made for applications up to 800 A and fits both 630 A and 1250 A bushings
    (Interface “C1” and “C2”) as specified by EN50180 and EN50181.
  • RSTI-68R-HT connector is compatible with a CLC/TS 50537 compliant bushing.
  • Suitable for train interior and exterior HV connections (mechanical protection recommended for exterior installations).
  • The compact design supports the use of double “T” connections (stacked or
    inline joint) inside standard cabinets and on the train roofs.
  • The wide application range covers cable cross sections from 50 to 240 mm2.
  • Conductor connection with 800 A DIN compression copper lugs.
  • Suitable for – but not limited to – 18/30 kV and 26/45 kV cables for Rolling Stock such as:
