产品特点 Product Features

内部采用分离空气绝缘型式，使相间的安全净距和爬电距离远大于国家标准规定的要求。设备内部相间绝缘体采用高强度的环氧树脂绝缘 材料，有效的提高了母线槽设备的抗动、热稳定能力，满足各种端条件下的稳定运行。外壳采用弯板一次成型波纹结构，因此体积小外形美观大方，大大增强了传统母线槽的机械强度载荷能力。

The interior employs an isolated air-insulation design, ensuring both the safe clearance and creepage distance between phases significantly exceed the requirements specified by national standards. The phase-to-phase insulation within the equipment utilizes highstrength epoxy resin material, effectively enhancing the busway's dynamic and thermal stability to maintain reliable operation under extreme conditions. The enclosure is formed with a one-piece corrugated structure through bending technology, resulting in a compact size and elegant appearance while substantially improving the mechanical load-bearing capacity compared to conventional busways.

适用范围 scope of application

空气绝缘母线槽适用于交流三相四线制、三相五线制、频率50-60Hz，额定电压至660V，额定工作电流250-5000A 的供配电系统，承担配电任务，用于低压配电屏与大、中型负载的连接，主要用于现代化的车间、厂房和高层建筑。

Air-insulated busways are suitable for AC three-phase four-wire and three-phase five-wire systems, with a frequency of 50–60 Hz, rated voltage up to 660V, and rated operating current ranging from 250A to 5000A. They serve power distribution functions, connecting low-voltage distribution panels to medium and large loads, and are primarily used in modern workshops, industrial plants, and high-rise buildings

结构特点Structural characteristics
