CPI Running Rail Connectors are designed as a permanent connection for copper conductor to a variety of rails used in Heavy Rail Mass Transit systems. Constructed with a heavy duty aircraft-quality steel spring member, copper cable nest, indentor, hex head bolt and locking nut.
No drilling in rail or need to weld conductor to the rail!
Rail is not subjected to warping by excessive heat or weakening by drilling
Labor saving - installation time can take as little as 10 minutes per connection
Fewer rail connections required due to large conductor capacity (Single conductors up to 1000 kcmil, Dual conductors up to 750 kcmil)
Large conductors can be bent away from the rail after installation without the risk of damaging the connector
The clamp is an active spring applying a consistent force on the conductor ensuring a positive connection through heat cycling and train vibration
The J-shaped spring member of the connector helps overcome loosening issues, problems associated with harsh train vibration, by flexing rather than breaking - a static-type connection doesn't have this resiliency and could crack under prolonged vibration
Consistent spring pressure prevents moisture and contamination from seeping into the connection
All copper components are tin plated and steel components are galvanized
