IP54 IP66 Fire Resistant Busway Bus Duct System With Strong Installation Adaptability

Factory Direct Sales Fire Resistant Busway Ducts With Strong Installation Adaptability

Product Description:

Fireproof bus duct, also known as fire-resistant bus duct, is a specially designed enclosed metal distribution equipment, which is composed of conductive bars (usually high-purity copper or aluminum), special insulation materials, and metal shells (such as steel plates or aluminum alloys). Its core mission is to maintain the integrity of the circuit within a specified time (such as 90 minutes, 120 minutes, or 180 minutes) when a fire occurs or the ambient temperature rises sharply to several hundred or even thousands of degrees Celsius, ensuring uninterrupted power transmission and supporting the operation of critical equipment. This is fundamentally different from ordinary bus ducts or bus ducts with only flame retardant function, which usually cannot maintain normal power supply under long-term high temperature flames.

Features:

1. Using inorganic insulation materials (such as mica tape, mineral insulation, etc.) and fireproof coating treatment, the circuit integrity can be maintained at a high temperature of 950 ℃ and pass a 1.5-hour combustion test. ‌

2. By designing double-layer hollow side panels, heat dissipation areas, and convection holes, the heat dissipation efficiency is improved to adapt to high current transmission scenarios. ‌

3. The shell is made of cold-rolled steel plate or stainless steel material, combined with fireproof insulation layer (such as rock wool, aluminum silicate fiber), effectively isolating high temperature gases and open flames. ‌

4. Suitable for scenarios with high fire prevention requirements such as chemical, metallurgical, airport, nuclear power plant, underground pipe gallery, etc., supporting horizontal/vertical installation
