Thank you for your attention to ZhongYuan water supply equipment [Knowledge News Information] column! The summer solstice is one of the early confirmed solar terms in the 24 solar terms. In the seventh century BC, the ancestors used Tugui to measure the sun's shadow, and determined the summer solstice. Although the summer solstice indicates that the hot summer has arrived, it is not hot yet. The temperature will continue to rise for a period of time after the summer solstice.

安装高压穿墙套管的要求

　　1.穿墙套管应根据连接导线(母排)选用相同材质的导电杆，如材质不同，需通过铜一铝过渡板连接。

　　2.穿墙套管户外引线需制作“U”形滴水弯头，如用绝缘导线，则要在“U”形弯头底部将绝缘切口以利泄水。

　　3.穿墙套管水平安装时法兰在墙外侧;垂直安装则法兰在上方。

　　4.穿墙套管*距离，一般规定35kV为60em;10kV为45cm，如用于潮湿环境，应适当增大距离。

　　5.穿墙套管一般宜固定在厚度为8～20mm钢板上，并使孔径大于套管嵌入部位5mm以上;固定板为混凝土板时，*厚度不得超过50mm，而且不得将法兰埋人混凝土或抹灰层内。

　　6.进、出线双回路的穿墙套管为避免干扰，*小距离应相距2m以上。
