Dual-Conductor Cast Resin Busduct

The epoxy cast busway has slightly poorer heat dissipation than the compact busway. Therefore, under the same current-carrying capacity, the conductor cross-sectional area used in the cast busway is generally larger than that of the dense busway. To increase the busway's current-carrying capacity, simply increasing the conductor cross-section linearly with the current ratio will face a contradiction between heat dissipation efficiency and conductor temperature rise. If internal heat cannot be dissipated, excessive temperature rise will cause the actual current-carrying capacity to increase far below the theoretical value. The design of double-row cast busways can effectively solve the temperature rise problem. By increasing single-row conductors to double rows within the same insulation space, the heat dissipation area is expanded and efficiency is improved, practically enhancing the rated current-carrying capacity.

With the dual advantages of high current-carrying capacity and high protection, the double-row conductor epoxy cast busway is widely suitable for complex scenarios with strict requirements for power transmission reliability and high current-carrying capacity. In the industrial field, it can be used in strongly corrosive and dusty environments such as metallurgical workshops and chemical parks. The fully sealed structure cast with epoxy resin can resist the erosion of acid mist and metal dust, and the double-row conductor design enables the current-carrying capacity to reach up to 6300A, meeting the centralized power supply needs of large equipment such as rolling mills and reaction kettles.
