Protection level: IP66
Current level: 400~6400A
Applicable places: Mainly used in pit construction, important control centers, public places with high traffic such as subways, and places with high fire prevention requirements.
Product features: The shell is composed of a mixture of cold-formed thin steel profiles. The side panels on both sides are our factory's unique double-layer hollow structure, which effectively prevents high-temperature gases or open flames from directly entering the interior of the bus duct through tight hollowing. The surface of the busbar trunking shell is galvanized and sprayed with fireproof coating (when exposed to fire, the coating can quickly expand at a geometric speed on the surface of the busbar, forming a dense carbonized insulation layer, sealing all gaps in the busbar shell, and preventing high temperatures from directly entering the inside of the busbar).
It is a product developed by our company based on the structural characteristics of dense bus ducts, using fire-resistant, heat-insulating, and flame-retardant materials. It has the advantages of compact structure, small volume, high temperature resistance, fire resistance, and large transmission capacity. The use of this product can ensure that power supply is maintained for a period of time in the event of a fire, and there is sufficient time to start fire extinguishing equipment, smoke exhaust ventilation, and smoke exhaust. This product can ensure that power supply is maintained for a period of time in the event of a fire, and there is sufficient time to start fire extinguishing.
