In simple terms, it is a high-current transmission system that uses metal busbars instead of traditional cables.

Advantages compared to cables

Core Advantages

1. Safety Protection, Multiple Guarantees

Utilizing a split air insulation structure, the phase-to-phase safety clearance and creepage distance far exceed national standards, effectively eliminating short-circuit risks. Internal insulation components are made of high-strength epoxy resin, significantly improving the product's resistance to dynamic and thermal stability, and capable of withstanding instantaneous short-circuit current surges, protecting the power distribution system. Safety guards are installed at the sockets, which can be closed and sealed with lead seals under normal conditions to prevent dust, foreign objects from entering, and accidental operation. Power does not need to be disconnected when plugging in the junction box; the ground wire is always connected before disconnecting, further enhancing operational safety. The product's protection rating reaches IP40, which can be increased to IP54 with dedicated accessories, offering excellent dust and moisture resistance and adaptability to various indoor environments.

2. High-efficiency heat dissipation, energy saving and consumption reduction

The conductor uses high-purity electrolytic copper with a copper content of over 99.99%, and the surface is tin-plated, which is anti-oxidant, highly conductive, has low resistivity, and low power loss. The outer shell is made of Maanshan Iron & Steel's high-strength cold-rolled steel with a one-piece corrugated structure, which combines excellent mechanical strength and heat dissipation performance. Combined with natural air convection, it forms a dual heat dissipation system. Compared with traditional cables, the temperature rise is reduced by 25%, and the current carrying capacity is increased by 30%. When carrying the rated current for a long time, the temperature rise of the conductive parts is strictly controlled within the standard range, eliminating the need for an additional cooling system and reducing operating costs.

3. Convenient installation and flexible adaptation

Adopting a modular design, it supports various connection methods such as straight sections, bends, and T-shaped branches. It can be flexibly combined and spliced according to site requirements to adapt to different wiring scenarios. Equipped with automatic compensation connection and single-bolt clamping terminals, it has high adjustability. The butt-mounting method greatly saves installation time and reduces labor costs. Ample busbar connectors are provided, supporting flexible branching of connector boxes. Loads can be connected to busbar units via the shortest path. Subsequent additions, relocations, or renovations of workshop equipment do not require changes to the busbar system, offering excellent interchangeability. No replacement of the outer casing is needed when adjacent current ratings change.

4. Robust and Durable Structure

The outer casing is manufactured using a one-piece molding process, resulting in high mechanical strength. With a span of 6m, the busbar center can bear a load of 60kg. Under non-uniform temperature changes, the center offset of the casing does not exceed 10mm, providing strong vibration and impact resistance. The casing surface uses an electrostatic spraying process for corrosion and rust prevention, extending service life. All components undergo rigorous testing. The product has passed power frequency withstand voltage and thermal stability tests, showing no significant deformation after testing. Under normal conditions, the insulation resistance of each section is not less than 50MΩ, allowing for long-term safe operation under full load, with a service life of decades.
