Single-pole Insulated Conductor Rails For EOT Crane 50ton
The JDC-H type conductor rail system is a modern power supply system using single-pole insulated conductor rails. It complies with the latest regulations and provide the electric energy for mobile consumers. The conductor rail material is copper(200A-5000A),aluminum(150A-3000A). 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 +115℃ is available, also for low temperature conditions, it could be up to -40℃.
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: CCC,ISO9001 and CE.
1, the phase line is Color green, the ground line is yellow-green plastic housing .Standard length is 6.0 m long,Other sections are available.
2, Hangers
Standard brackets for powerail attachment to crane girders are available.Powerail with sliding and fix point hangers.
Standard distance between suspension points for indoor and outdoor.Installations space: 1200mm.
Material: galvanized steel
3,Jointing material
Snap-in joint splices provide mechanical end electrical continuity.They include insulated protection covers.
4,Feed Sets
Line feeds (any joints) or end feeds.
5,End caps
The open ends of the conductor are closed by end caps.
6,Expansion section
The Expansion sections are required to compensate the different expansions between copper conductors and steel or concrete structures, in varying temperatures without interrupting electrical power.
Expansion joints are used when the Power-ail 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 die-energized within a conductor rail system.To prevent a voltage bridging by current collector two air gap isolating sections should be installed.
8,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 collectors for transfer applications and higher amperage.
