CADWELD® Connections for Train Control & Neg Power Return

CADWELD® Connections for Train Control & Neg Power ReturnPrint this page

Service time and over 100 million installed bonds prove that the CADWELD® Process provides the ultimate in desirable features for railroad signal bonding. ERICO provides an offering of both rail head and rail web signal bonds.

Features

Rail Head Bonds

  • Industry standard for joint bonding
  • Provide maximum detection of broken rail within the splice bar, contributing to the safest possible signal system
  • 3/16 dia./14 mm2 - 250 kcmil/120 mm2

CADWELD rail head joint bonds provide:

  • Maximum broken rail protection
  • Unchanging electrical resistance
  • Maximum corrosion resistance
  • Maximum protection against physical damage – 7 to 1 shear strength over a pin head bond
  • Are not destroyed by rail end build up
Rail Web Bonds
  • Utilize preformed Type W terminals
  • Provide a convenient means of connecting all cable outside the confines of the splice bar
  • Connection is least susceptible to vibration fatigue and kept clear of dragging equipment and maintenance machinery
  • 3/16 dia./14 mm2 - 500 kcmil/250 mm2

Applications

CADWELD rail signal bonds can be used on old, worn or new rails.

Engineering Specifications
All electrical connections to rail should be welded with the CADWELD copper-based exothermic welding process as manufactured by ERICO.

All connections within the splice bars should be to the "field" side of the railhead.

All other connections should be made on the rail web at the neutral axis.

Due to a policy of continued product development, specifications are subject to change without notice.
