Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • When selecting fire-resistant bus ducts, it is recommended to match key technical parameters such as fire resistance duration and current carrying capacity according to actual application scenarios (such as high-rise buildings, data centers, or industrial plants) to ensure that specific fire protection level requirements are met.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers can usually provide more stable product supply and technical support.
  • For distribution systems that require high safety, the insulation material performance and fire-resistant coating process of fire-resistant bus ducts are key evaluation points. It is recommended to comprehensively consider parameters such as short-circuit tolerance.
  • Different specifications of fire-resistant bus ducts are suitable for dense distribution or long-distance transmission scenarios. Before procurement, it is necessary to clarify the space limitations and heat dissipation requirements of the installation environment to avoid increasing the cost of later renovation due to design inconsistencies.
