A Bare, Stranded Copper
Conductor
B Composite Okonite-Okolon
Insulation
Insulation
Okonite EPR® insulation is a heat, moisture and chemical resistant,
mechanically rugged compound. The insulation thickness for 500 kcmil
(negative return) is 12/64" and for 2000 kcmil (positive), also 12/64"
Jackets and Finishes
The Hypalon (CSPE) jacket applied with this cable provides excellent
resistance to mechanical abuse, flame, weathering most oils, acids and
alkalies.
Applications
Okonite DC Traction cables are designed for superior aging and higher
reliability characteristics for electric railroad service in damp brackish
locations including direct buried and other underground installations
subject to vibration of train operation.
