Busbar trunking systems provide dedicated power distribution solutions for factories, processing plants, utilities and other industrial facilities. Busbars offer higher capacity, safety and flexibility compared to cables for delivering large load currents.
Industrial busbar systems consist of bare or insulated copper/aluminum conductors enclosed in non-metallic or metal housings. Tap-off connections allow interfacing equipment loads anywhere along busbar length. Busbars can be laid out to optimize power flow, monitoring and redundancy.
With high demands for capacity, reliability and safety in industries, busbars present an efficient alternative to cables. When customized by experts like GRL, industrial busbars ensure optimal power delivery tailored to facility needs. Contact us if you need.
Busbar power distribution provides significant advantages in industrial settings:
Busbars are rated from hundreds to thousands of amps, exceeding cable capacity. They can deliver power to high draw motors, drives and machinery.
Large conductors used in busbars minimize I2R heating losses, ensuring efficient power transfer.
Busbars carry more current per square inch compared to cables, saving space. Custom shapes optimize area utilization.
Layouts integrate future taps and redundancy loops. Rating zones cater to evolving demands.
Prefabricated busbar sections with tap-off boxes simplify installation compared to pulling cables.
Proper insulation, IP ratings and fireproof designs prevent hazards. Faults can be contained.
Busbar trunking offers efficient, scalable and safe power distribution for diverse industries.
Key aspects for designing optimal industrial busbar systems:
Survey the electrical loads from equipment, lighting and controls. Analyze starting and running currents, and duty cycles.
Select appropriate system voltage. Determine busbar current rating based on peak demand and de-rating factors.
Layout design must comply with IEC 60439, IEC 61439, NFPA 70 and other applicable standards.
Busbar enclosures must withstand harsh environments. Supports should be designed for forces from short circuit currents.
Allow adequate access space for installation, maintenance and expansion. Coordinate positioning with other services.
Select busbar insulation and enclosures suitable for ambient conditions, corrosion and outdoor installation if applicable.
Carefully considering these factors ensures an optimal industrial busbar system design.
Proper installation ensures safety and performance:
Install dedicated cable trays or wall brackets to securely mount busbar enclosures. Anchor supports to rigid building structure.
Use high quality lugs matched to conductor size. Tighten bolted joints to specified torque values for low contact resistance.
Maintain adequate spacing between busbar phases and other services. Cover joints with insulation boots. Install insulated busbar housing.
Install expansion joints to accommodate busbar lengthening during heating. Manage rating transitions.
Verify earth continuity, insulation resistance and functional operation before energization. Check for defects.
Care during installation prevents issues and ensures optimal performance.
To maximize operational life of industrial busbars:
Vacuum or wipe busbar enclosures to remove accumulated dust and debris which are fire hazards.
Check for signs of overheating or insulation damage. Scan joints using thermal imager. Verify tightness of connections.
Test insulation resistance periodically. Check earth continuity. Inspect fuse condition.
Repair busbar defects like cracked insulation and overheated joints immediately. Replace damaged sections if needed.
Reconfirm insulation, warning signs, covers, and access restrictions following any maintenance or fault.
Proactive maintenance reduces probability of failures.
Busbar hazards require adequate precautions:
Use proper insulation class for operating voltage. Maintain type test and field test reports.
Post clear hazard signs at busbar access points informing about voltage. Install live indicators.
Prevent unauthorized access into busbar sections through physical barriers and locks.
Provide alternate feeder connections using removable links to critical loads to maintain supply during busbar isolation.
Use fire retardant insulating materials. Install smoke detection near busbars. Keep nearby fire extinguishers.
A focus on safety during design, installation and operation ensures hazard-free busbar function.
Busbar systems offer flexibility to adapt to specific industrial facility requirements:
Select optimal busbar housing dimensions and materials. Choose metallic, non-metallic or sandwich panel enclosures.
Provide fixed conventional tap-offs or plug-in tap-off modules to simplify adding future loads.
Incorporate removable sections or links between busbars feeding critical equipment to implement redundancy.
Add sensors, data loggers and remote analytics to monitor current, temperature and faults in real-time.
Provide accessories like expansion joints, fire barriers, vibration dampers, hangers and insulation boots.
