Factory-Delivered Intensive Busbar Duct Cable Enclosure Fire-Resistant Aluminium Alloy Copper Busbar

Product Description:

There is a distinction between "fire-resistant bus duct" and "fire-resistant bus duct" under strict technical standards: the shell and insulation layer of fire-resistant bus duct are usually made of fire-resistant materials that can withstand high temperatures ≥ 1100 ℃ and insulation materials that can withstand high temperatures ≥ 300 ℃. Their fire-resistant time is longer, for example, they can operate at full load for more than 8 hours at high temperatures of 920-1050 ℃; The fireproof busbar trunking may mainly achieve a certain period of fire protection by adding fireproof partitions or coating fireproof coatings on the shell. Its fire resistance time is relatively short, such as 30 minutes, 40 minutes, and 60 minutes at high temperatures around 800 ℃.

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
