320A To 500A Conductor Rails , High Power Shrouded Bus Bar System
Detailed Product Description
The JDC-H conductor rail system is a modern crane power supply
system using single pole insulated conductor bars. It complies with
the latest regulations and provides the electric energy for
material handling equipments such as overhead cranes.
The aluminum shrouded busbar mobile electrification system is provided with a proven and patented stainless steel contact
surface. Any numbers of poles can be installed vertically or
horizontally, on straight or curved systems.
Design features
Housing
The well insulating green plastic housing holds 3-6 conductors.
Usually 4m standard length and other length to meet your runway
requirements are available. The ground line is identified by the
yellow color so that avoiding phase reversing.
Collectors
The current collectors are made of carbon brush, re-inforced nylon
and galvanized or spray-paint metal material. Spring loaded carbon
brushes maintain uniform contact. Connecting cables and hinged or
flexible towing arms included. Double Current collectors for
transfer applications and higher amperage are available.
