Fire-resistant busway is composed of a fire-retardant coated housing, insulated busbars wrapped with fire-resistant mica tape, and supports made from fire-resistant insulating materials. The supports have multiple grooves, where the busbars are inserted and secured. At one end of the busway is a busway junction box, and within the busway is a busbar tapping box. The fire-resistant busway boasts excellent insulation properties, allowing continuous use in both normal and fire conditions for over an hour, making it suitable for high-rise buildings and critical facilities, replacing fire-resistant cables for power and distribution. It refers to the fire protection main trunk that can maintain circuit integrity under flame conditions, offering both fire resistance and sprinkler system requirements.

Structural Performance:

1. Employed a reasonable "sandwich" phase line tightly overlaid structure design, with a compact busbar channel shape and small volume. The busbar system boasts advantages such as low impedance, reduced voltage, and excellent dynamic and thermal stability.

2. The housing is made of a mixture of cold-formed thin steel profiles. The side panels feature our factory's unique double-layer hollow structure, which effectively prevents high-temperature gases or open flames from directly entering the busbar channel interior. The surface of the busbar channel housing is zinc-plated and coated with fire-retardant paint (when exposed to fire, the paint expands rapidly at a geometric rate on the busbar surface, forming a dense carbonized insulating layer, sealing all gaps in the busbar channel housing to prevent high temperatures from entering the interior of the busbar).

3. The connectors use fire-resistant insulating components for reliable and convenient connections.
