JDC-H Conductor Rail System are easy and exact mounting with
multiple supporting bracket and a safe source of power for current
capacities up to 3000 A(copper conductor up to 5000A) for many
power loads that are predominantly subjected to rough operation,
e.g., traveling cranes, loading bridges, container handling
equipment, monorail systems, coking machinery, electric hoists,
Detailed Product Description
The JDC-H conductor rail system is a modern power supply system
using single pole insulated conductor rails. It complies with the
latest regulations and provides the electric energy for material
handling equipments such as overhead cranes.
The aluminum conductor rail 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
The entire conductor rail system can be installed indoor or
outdoor. It is insulated conforming to Current Safety Regulations.
Ground insulation cover is marked yellow-green on one side over the
entire length of the rail.
R Type: for curves R≥1200mm.
Approved and listed by: CCC, ISO9001 and CE.
The ranges of applications of JDC Insulated Conductor System:
- Overhead and elongated tracks for cranes.
- Electric hoists, electric tools, stacking systems, monorail
- Monorail systems.
- Other applications for supplying power to moving power load.
- Compact and flexible arrangement for poles.
- High safety insulation housing, corrosion resistance.
- Easy and exact mounting with multiple supporting bracket.
- Easy installation.
- Variation in temperature, large power available.
Generally, the housing line is in green and ground line in
yellow-green. Standard length is 4m or 6m, other sections are
Snap-in joint splices provide mechanical and electrical continuity.
Insulated protection covers are included.
End feeds or line feeds are available.
The open ends of the conductor are closed by end caps.
Standard brackets for conductor attachment to crane girders are
available. Conductor is with sliding and fix point hangers.
Standard distance between suspension appoints for indoor and
outdoor installations: 1500mm to 2000mm.
The Expansion sections are required to compensate the different
expansions between copper conductors and steel-or concrete
structures, in varying temperatures without interrupting electrical
Expansion joints are used when the Powerail length between feeds,
curves, switches or other fix points is exceeding 20m. Install
expansion joint according to actually installation.
Isolating sections are required if parts of the system or
individual rails are to be de-energized within a conductor rail
system. To prevent a voltage bridging by current collector two air
gap isolating sections should be installed.
The current collectors are made of carbon brush, reinforced 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.
