480V HEAD END POWER TRAINLINE

Clements National Cadillac® brand of 480V jumpers and receptacles provide head end power (HEP) to locomotive hauled passenger rail cars.

Our jumpers feature integrally molded plugs and receptacles that protect the contacts from condensation, dust and debris, and can also use power from a power car or wayside ground based source.

The receptacle skirt features a patented, integrally molded, expandable stabilizer to eliminate insertion problems often encountered in connectors with glued support rings. This design reinforces the front of the connector head.

27 Point (COMM) jumpers and receptacles convey car control and communication signals throughout the train such as:

  • Door controls
  • Public address
  • Brake applied/released indications

27 Point Multiple Unit (MU) jumpers and receptacles carry traction and dynamic brake commands and can be found between:

  • Locomotives coupled together
  • Cab car and locomotive
  • Locomotives or power cars placed at opposite ends of the train

In order to tolerate extreme weather conditions as well as flying rocks and debris, we use EPDM (ethylene propylene diene monomer) for our cable material as it offers great flexibility, durability, and resistance to moisture.

The design and construction of the 27 Point Series product also holds up to frequent connecting and disconnecting, and rough handling.

All Clements Cadillac® 27 Point Series connectors conform to all industry specifications including Amtrak, AAR, and APTA
