[0002] Electricity is a very important modern energy source. Traditionally, the power system is divided into three major systems: power generation, transmission and distribution. The electric energy generated by the power generation system is transmitted through the transmission system and finally distributed to various users by the distribution system. Power generation, transmission and distribution all require a large number of electrical products to support them. From large generators to small transmission lines, they are all part of it. Transmission and distribution equipment include transformers, voltage transformers, current transformers, lightning arresters, disconnectors and oil switches, etc., and most of them are installed and used outdoors on transmission and distribution equipment racks. When installing low-voltage cables on transmission and distribution racks, the cables need to be fixed with fixings and water-avoidance bends need to be set to prevent rainwater from entering the distribution box through the cables. However, the existing fixings cannot be adjusted in height according to the actual curvature required by the cable water-avoidance bend.
