The WQYTC2-TL energy-saving busway not only shares the same advantages and features as the WQYTC2 energy-saving busway but also offers the following benefits: 1. Substitution of aluminum for copper conserves copper resources. 2. The use of copper-aluminum composite conductor material overcomes issues such as thin and easily peeling coatings in copper or tin-plated aluminum bars. It also prevents oxidation at aluminum-aluminum joints and electrochemical corrosion at aluminum-copper joints, which can increase contact resistance and lead to electrical failures. 3. Leveraging the cost-effectiveness of materials, a generous conductor cross-section is designed, resulting in lower temperature rise and higher reliability. 4. Lightweight design simplifies installation, saving time and labor. It reduces investment costs and delivers significant social and economic benefits.
