產品特點 Product Features

內部采用分離空氣絕緣型式，使相間的安全凈距和爬電距離遠大于國家標準規定的要求。設備內部相間絕緣體采用高強度的環氧樹脂絕緣 材料，有效的提高了母線槽設備的抗動、熱穩定能力，滿足各種端條件下的穩定運行。外殼采用彎板一次成型波紋結構，因此體積小外形美觀大方，大大增強了傳統母線槽的機械強度載荷能力。

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.

適用范圍 scope of application

空氣絕緣母線槽適用于交流三相四線制、三相五線制、頻率50-60Hz，額定電壓至660V，額定工作電流250-5000A 的供配電系統，承擔配電任務，用于低壓配電屏與大、中型負載的連接，主要用于現代化的車間、廠房和高層建筑。

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

結構特點Structural characteristics

● 體積小、結構緊湊，具有抗銹蝕性和好的散熱性、接地性。其的中空型雙層結構，使每片外殼都具有管材的高抗彎性，從而使母線槽系統的抗繞彎性大大增強。

● 采用標準配置的單臂鎖緊避震接頭器，連接可靠方便。

● 可方便地設置饋電插口，上下兩面均可同時設置，且不降低其抗彎強度。饋電插接口的安全防護等級達IP5X( 符合標準IEC529)。

◎ 絕緣配置

● 母線介質絕緣采用高效絕緣材料- 聚酯薄膜，該材料具有較好的耐高溫性( 在高溫中無有毒氣體釋出)、較高的介電性能，絕緣等級為B 級。也可采用高檔絕緣材料“塑料王”- 聚四氟乙烯定向薄膜(SFM-3), 該材料耐高溫等級很高(-180℃ -+250℃ ), 單層耐壓6000V, 絕緣等級“C”,絕緣老化壽命50 年以上，為現行使用絕緣材料中性能產品。

● Air-insulated busways feature a compact design with excellent corrosion resistance, heat dissipation, and grounding performance. Their unique double-layer hollow structure provides each enclosure segment with pipe-like bending resistance, significantly enhancing the overall system's torsional strength.

● The system incorporates standard single-arm locking vibration-damping connectors for reliable and convenient installation.

● Power tap-off openings can be flexibly arranged on both top and bottom surfaces without compromising bending resistance. These tap-off interfaces achieve IP5X protection rating (compliant with IEC 60529).

◎ Insulation Configuration

● Busbar insulation utilizes high-efficiency polyester film, which offers superior high-temperature resistance (no toxic gas emission under extreme heat) and dielectric properties, rated as Class B insulation. Alternatively, premium polytetrafluoroethylene (PTFE) oriented film (SFM-3) can be used, featuring an extreme temperature range (-180℃ to +250℃ ), single-layer withstand voltage of 6000V, Class C insulation rating, and insulation aging life exceeding 50 years, representing the highest-performance insulation material currently available.
