Crane Power Supply Jdc Type Conductor System

Crane Power Supply JDC Type Conductor System
Introduction:

Jdc-H Type Conductor Bar for Single Pole Insulated Conductor Rail is a modern power supply system using single-pole insulated conductor rails. It complies with the latest regulations and provides the electric energy for mobile consumers. The conductor rail material is cooper (200A-3000A). The aluminium 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 systems.

The conductor rail system can be installed indoor or outdoor. For high temperature conditions, a high temperature insulation cover up to +115ºC is available, also for low temperature conditions, it could be up to -40ºC.

The entire conductor rail system is insulated to current safety regulations, it is entirely protected against direct contact. Ground insulation cover is marked yellow-green on one side over the entire length of the rail.
Type-R: Curves for R≥1200mm.

Approved and listed by: CCS, ISO9001 and CE.

Main Components:

1,Insulation
Generally, the phase line is color green, the ground line is yellow-green plastic housing; For H19 system, the standard length is 4.5m long, and for other systems, the standard length is 6.0m long. Other sections are available.

2, Joint material
Snap-in joint splices provide mechanical and electrical continuity. They include insulated protection covers.

3, Feed Sets
Line feeds (any joints) or end feeds.

4, End caps
The open ends of the conductor are closed by ends caps.

5, Hangers
Standard brackets for conductor attachment to crane girders are available. Conductor with sliding and fixpoint hangers.Standard distance between suspension points for indoor and outdoor installations: 1500mm to 2000mm.

6, Expansion section 
The expansion sections are required to compensate the different expansions between copper conductors and steel or concrete structures, in varying temperature without interrupting electrical power. Expansion joints are used when the power rail length between feeds, curves, switches or other fix points is exceeding 200m. Install one expansion joint according to actually installation.

7,Isolating section
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.

8,Switches
Power rail for working areas and transfer applications see End cap

9,Collectors
The current collector are made of carbon brush, re-inforced nylon and galvanized or spray-paint metal spring loaded carbon brushes maintain uniform contact. Connecting cables and hinged or flexible towing arms included. Double collectors for transfer applicaitions and higher amperage.
