Technology Index of introduction RMU using metal-enclosed box-type structure, the main switch and the cabinet is a fixed installation, the entire RMU can be divided into upper and lower portions, the upper portion cabinet including bus room, opening room, the low pressure chamber, and the lower cable (outlet cabinet including fuses) separated to avoid mutual influence. Therefore, not only improves safety, but also easy to install, repair, but also, if necessary, replace the whole upper unit. RMU has ample cable room that can accommodate fuses, surge arresters, current transformers, switches and other components under the ground, an observation window and door safety interlocks, cable cover can be removed for easy cable installation.
