Product Definition
The compact busway features a typical sandwich structure inside, with a well-optimized design and superior performance. It offers stable and reliable operation, high surface current density, excellent heat dissipation, reduced voltage drop, strong resistance to mechanical impact, and easy installation. With current ratings ranging from 250 A to 6,300 A, it can meet the power transmission and distribution needs of diverse customer segments.
Sandwich Conductor Structure
1. Full-length density, preventing the “bacon effect.”
2. Compact structure, occupying less building space
3. Conductors are closely arranged for uniform heat dissipation, resulting in lower temperature rise.
4. Busbars at the connectors shall not be bent; high density, low impedance.
5. Phase-error-proof design to ensure correct phase sequence during installation
6. Current-carrying capacity is unaffected by installation location or method.
Aluminum-magnesium alloy casing
1. The busbar trunking system utilizes lightweight, extruded aluminum alloy profiles as the enclosure, with a wall thickness of no less than 2 mm, providing high mechanical strength and enabling it to readily meet a wide range of special application requirements.
2. The coated enclosure exhibits excellent corrosion resistance and can withstand a 1,200-hour salt spray test;
3. The aluminum alloy enclosure boasts excellent heat dissipation performance, with a thermal dissipation capacity twice that of a steel enclosure;
4. The aluminum alloy enclosure features serrated heat sinks, providing a heat dissipation area more than 1.5 times that of conventional enclosures, thereby improving thermal performance and increasing current-carrying capacity. It also boasts excellent electrical conductivity, with the overall enclosure grounding capacity no less than 50% of the phase conductor’s rating.
5. The aluminum alloy enclosure is a non-magnetic, environmentally friendly material that effectively prevents eddy current and hysteresis losses from adversely affecting the busbar trunking system.
