Mechanical Structure Design and Test of Multi Wire Diameter High Voltage Cable Cutting Machine

Abstract

The problem in China's power industry is that the aluminum strand stripping efficiency of high-voltage cable is low, making it easier to damage the wire core used for cable connection. This paper proposes a multi wire diameter cable cutting machine based on the requirements of aluminum strand stripping of high-voltage cable. The key components of the cutting machine are theoretically analyzed, and the effects of the function of the machine and the single extension distance of the push rod on the cutting effect and cutting rate are experimentally studied. The experimental results show that when the driving motor speed is the same, the cutting rate increases with the increase of the extension distance of the push rod; When cutting 22mm and 50mm wire diameter wires, the single extension of the push rod into 10mm aluminum strand stripping effect is the best. When cutting 35mm wire diameter wires, the single extension of the push rod into 5mm has a better effect. The cable cutting equipment can achieve the design goal and better meet the requirements of aluminum strand stripping operation.
