1．產品簡介  Product Introduction

免維護玻璃鋼絕緣低壓交直流母線槽是空氣絕緣母線槽、密集型母線槽和環氧樹脂澆注型母線槽的升級換代產品。該產品使用波紋形薄板作為導體，散熱性能好，導體利用率高。導體中間接頭、端部接線端子均采用焊接連接，減小了導體接觸電阻，可以免維護。導體外部覆蓋玻璃鋼扁管，在導體與玻璃鋼扁管之間填充導熱性好、耐高溫的石英砂顆粒，即提高了母線的防護等級，使其可以在浸水、直埋地下等特殊條件下運行，同時還增加了導體的散熱性能及母線槽的機械強度。免維護玻璃鋼絕緣低壓交直流母線槽可做為交流線槽亦可做為直流母線槽，即可水平布置又可豎直布置，是具有很高性價比的產品。

The maintenance-free FRP insulated low-voltage AC and DC busway is an upgraded product of air-insulated busway, dense busway and epoxy cast busway. The product uses corrugated sheet as the conductor, which has good heat dissipation performance and high conductor utilization rate. The middle joints and end terminals of the conductors are all welded to reduce the conductor contact resistance and can be maintenance-free. The conductor is covered with FRP flat pipe outside, and the quartz sand particles with good thermal conductivity and high temperature resistance are filled between the conductor and the FRP flat pipe, which improves the protection level of the busbar, so that it can operate under special conditions such as water immersion and direct burial underground, and also increases the heat dissipation performance of the conductor and the mechanical strength of the bus duct. The maintenance-free FRP insulated low-voltage AC/DC bus duct can be used as AC trunking or DC bus duct, which can be arranged horizontally and vertically, and is a very cost-effective product.
