Bus trunking replacement switchboard solution

Busbar trunking systems offer a flexible, high-capacity alternative to traditional switchboards, enabling efficient power distribution with modular tap-off options and compliance with international standards.

Overview of Busbar Trunking Systems

Busbar trunking systems (busways) are modular electrical distribution systems designed to replace or supplement traditional cable and switchboard setups. They provide high-current capacity, low impedance, and flexible tap-off points, making them ideal for industrial plants, commercial buildings, and data centers. These systems allow for easy expansion, maintenance, and reconfiguration without major downtime.

Key Features

High Capacity & Voltage Ratings: Systems like C&S Electric's Sandwich Busbar Trunking support up to 7000A at 1000V AC, while Anord Mardix IBAR HX ranges from 800A to 6300A. Protection & Compliance: IP54/55/66 enclosures, seismic compliance, and adherence to IEC 61439 and BS EN 61439-6 standards ensure safety and reliability. Modularity & Tap-Off Flexibility: Tap-off points can be installed at standard or custom locations, allowing connection to sub-distribution boards or equipment without rewiring.

Specialized Applications: Data center busways, such as Vertiv PowerBar and Siemens SIVACON 8PS LData, provide hot-swappable connections, live monitoring, and minimal power loss for IT racks. Material Options: Copper or aluminum conductors with epoxy insulation or GI/aluminum enclosures for heat dissipation and durability.

Advantages Over Traditional Switchboards

Space Efficiency: Compact design reduces floor space requirements. Ease of Installation: Preassembled sections simplify installation and reduce labor costs. Scalability: Additional circuits or loads can be added without major rewiring.

Reliability: High short-circuit withstand capacity and low impedance improve system stability. Maintenance: Modular tap-offs and overhead routing allow maintenance without shutting down the entire system. Selecting a Replacement SolutionWhen choosing a bus trunking system to replace a switchboard, consider: Load Requirements: Current rating, voltage, and short-circuit capacity.

Environmental Conditions: Indoor/outdoor, IP rating, and seismic considerations. Application Type: Industrial, commercial, or data center. Flexibility Needs: Number and location of tap-offs, modularity, and future expansion.

Compliance: Ensure adherence to IEC, BS, or local electrical standards. Recommended SystemsC&S Electric SB & CB Series: High-capacity and medium-duty options with IP54/55/66 protection.
