China Expansion Joint for Nsp-H Series Unipole Conductor Rail

Factory Price Single Pole Insulated Conductor Busbar Safety Conductor System

Application
The ranges of applications of HFP Power Rail Enclosed Conductor System
1.Overhead and elongated tracks for cranes.
2.Electric hoists, electric tools, stacking systems.
3.Electric tools
4.Other applications for supplying power to moving power load.
Design features
Compact arrangement, corrosion resistance and simple assembly are its essential features.
Housing:
Color green, PVC housing for 4 conductors. Standard section 4 m.
Other sections are available.
The ground conductor is identified by international color code.
Phase reversing prevented by design of the collector and housing.
Joints:
Snap-in joint splices provide mechanical and electrical continuity. Insulated protection covers are included.
Feed Sets:
End feeds or line feeds are available.
End Caps:
The open ends of the conductor are closed by end caps.
Hangers:
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.
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 Powerail length between feeds, curves, switches or other fix points is exceeding 20m. Install expansion joint according to actually installation.
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.
Collectors:
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.
