Purchasing Guide

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

  • For procurement requirements that require the use of waterproof bus ducts, it is recommended to prioritize confirming the protection level (such as IP68) and rated current parameters to ensure compatibility with the load requirements of the distribution system, especially suitable for underground engineering or humid environments.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support or platform statistical information. Such suppliers usually provide more stable technical support and after-sales service guarantee.
  • In corrosive environments such as chemical industry, ships or outdoor substations, waterproof bus ducts need to pay extra attention to the corrosion resistance of shell materials (such as aluminum alloy or stainless steel) to avoid environmental factors affecting the service life.
  • For dense power distribution scenarios such as data centers or high-rise buildings, it is recommended to choose segmented waterproof bus ducts for easy installation and maintenance, reducing space occupation, and verifying the supplier's engineering case experience.
