Refractory Power Distribution Busbar NFMC-C Model 250~3150A Rated

Copper Material Refractory Power Busway Ducts NFMC-C Model 250~3150A Rated Current Strong Installation Adaptability Cable

Product Description:

The "sandwich" tight structure design of the fireproof bus duct has the advantages of low impedance, reduced voltage, and good dynamic and thermal stability, and can effectively prevent the formation of the "chimney effect" during a fire. The conductor connection part is usually made of double connected copper bars and fastened with insulated bolts, with low contact resistance and low temperature rise. Its protection level usually reaches IP54 or higher, which can effectively prevent dust and water from entering and adapt to humid environments.

Due to the use of excellent conductive materials and compact structural design, the current capacity of fire-resistant bus ducts can be made very large (with a maximum rated current of 6300A), far from being comparable to ordinary cables. At the same time, its voltage drop is small, which can reduce the loss of electrical energy during line transmission.

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
