Abstract

A high voltage cable outer sheath flexible electric cutter comprises a power head, a power head support is arranged on the power head, a cutter and an adjusting device for cutter position adjusting are arranged on the power head support, the adjusting device is fixed on an upper cutter body, the upper cutter body and a lower cutter body are fixed by a core shaft and a spring wrapped around the core shaft, the upper cutter body corresponding to the cutter is provided with an adjustable upper guide wheel, and the lower cutter body corresponding to the upper guide wheel is provided with an adjustable lower guide wheel. The high voltage cable outer sheath flexible electric cutter uses the power head and the conventional cutter, is adjustable in angle, and can radially lock and axially slide when in working state, the cut surface cutting effect is coherent and tidy, later production can be facilitated, and the operation is simple, convenient, safe and reliable.

Description

technical field [0001] The invention relates to a special electric cutter for cutting the outer sheath of a high-voltage cable, especially suitable for the production of 10-110 kV cable heads. Background technique [0002] With the acceleration of the construction of UHV power grids and urban and rural distribution networks, the construction of new substations, the renovation of old substations, and the aggravation of technical transformation tasks, the stripping and cutting of high-voltage cables has become an important link in the project. The outer sheath of high-voltage cables is mostly made of polyvinyl chloride plastic material. This material has good insulation performance, corrosion resistance, heat resistance, water resistance, and strong sealing performance, but it is greatly affected by temperature. Under normal temperature, it is not easy to manually cut through the outer sheath of high-voltage cables with traditional tools (cable knife, etc.), and the constructi...
