The general closed type clamp for replacing 5 UHV insulators comprises a front clamp, a rear clamp and tensioning devices, wherein the tensioning devices are arranged between the front clamp and the rear clamp, two ends of each of the tensioning devices are connected with the front clamp and the rear clamp, and the tensioning devices are used for adjusting the distance between the front clamp and the rear clamp when replacing insulators and 10 can exert tensioning force on the front clamp and the rear clamp. A first bushing is arranged in the front clamp, a second bushing is arranged in the rear clamp, and the shape of inner surfaces of the first bushing and the second bushing is matched with that of steel caps of insulators clamped in the front clamp and the rear clamp. The general closed type clamp for replacing UHV insulators comprises the front clamp 15 and the rear clamp with good strength and light weight, can adapt to insulators of different models, solves the problem of the stroke and poor loading capacity of the tensioning devices via hydraulic and mechanical combined lead screws, and reduces the length of the lead screws, thereby facilitating site carrying and lifting as well as storing in warehouses, being capable of effectively reducing the labor 20 intensity of operators working aloft and improving the working efficiency. 251/5 3 I 2 Figure 1
