Busbar Trunking System Overview
Busbar Trunking provides structured electrical power distribution between switchboards and connected equipment in industrial plants, commercial facilities, and infrastructure installations. The trunking assembly supports organized routing of high-current conductors while maintaining controlled termination between electrical distribution points.
Electrical Ratings and Standards
IEC 61439 compliant bus duct construction aligns the system with recognized switchgear and power distribution standards. Current ratings range from 800A to 5000A in aluminium busbars and from 630A to 6000A in copper busbars, supporting diverse facility load requirements.
Thermal and Mechanical Construction
The trunking structure is engineered for controlled heat dissipation, thermal rating stability, and mechanical stress endurance. Housing is available in electro-galvanized steel ranging from 1.5mm to 2mm thickness or aluminium wrap-around construction, supporting structured installation in electrical distribution corridors.
Protection and Grounding Configuration
Ingress protection options include IP4X, IP5X, and IP6X ratings depending on installation requirements. An integral earth arrangement supports grounding continuity along the trunking route, while Class B insulation contributes to stable electrical separation between conductors and enclosure.
Installation and Jointing System
Silver plated joints assist electrical continuity between trunking sections during installation. Rectangular and square housing formats support alignment within electrical rooms and plant corridors, while indoor and outdoor duty options enable deployment across varied facility layouts.
