　　10、室外安裝橋架安裝高度不能低于積雪、積水高度，同時考慮選用防水型蓋板，進出室外橋架、線槽，室內(nèi)須高于室外，防止雨水流入室內(nèi)。

　　10. The installation height of outdoor cable trays should not be lower than the height of snow and accumulated water. At the same time, waterproof cover plates should be considered. For outdoor cable trays and trunking, the indoor height should be higher than the outdoor height to prevent rainwater from flowing into the indoor area.
