RT-GFM High-Voltage Enclosed Common Enclosure Busway is specifically engineered for electrical connections between high-voltage switchgear (rated for 6kV, 10kV, 20kV, and 35kV) and transformers. It is widely deployed in power supply systems for large industrial plants, major substations, captive power plants in large enterprises, large-scale construction projects, and connections between generators and step-up transformers, ensuring reliable power distribution across critical infrastructure.

The product adopts a segregated phase structure, where each phase is individually insulated and housed within a robust alloy enclosure, meeting stringent standards for insulation performance and operational safety. By separating the three phases in air, it achieves balanced three-phase voltage distribution, reduced temperature rise, high currentcarrying capacity, and straightforward installation, enhancing system efficiency and longevity.

The busway is equipped with intelligent monitoring devices along its entire length, providing real-time insights into system performance and ensuring secure power supply operation. It incorporates a dedicated control wire trench, simplifying installation and maintenance processes while optimizing space utilization.

The busway’s side panels are constructed from heat sink-style aluminum-magnesium alloy profiles with a thickness of 3.0mm. The integrated cooling fins not only improve heat dissipation but also reinforce structural rigidity, allowing side heights of up to 305mm without additional reinforcements. Top and bottom covers are made from aluminum-zinc coated steel, contributing to the overall structural integrity of the assembled busway. Side panels and base plates are securely fastened using high-strength imported rivets, while cover plates are bolted to the side panels for easy access. Each busway section typically includes strategically positioned standard inspection openings on the upper side (optionally on the sides to suit site-specific needs). Advanced manufacturing techniques at inspection points and high-performance expansion joint technology ensure the busway enclosure achieves an IP54 protection rating, delivering durability and resilience in diverse operating environments.
