Description

Technical Field

[0001] The utility model belongs to the technical field of electric power construction, and more specifically, particularly relates to a cable truncating device for electric power line construction. Background Technique

[0002] A cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires.

[0003] During the construction process of electric power lines, it is necessary to truncate the cable. The existing truncating methods mostly involve operators holding the cable by hand and using a cold cutting saw to cut the cable to truncate it. For some cables with a longer diameter, the truncating time is longer, resulting in the operators having to hold the cable for a long time, which is time-consuming and laborious; and the way of holding the cable by hand by the operators may cause the cable to shift during the truncating process, resulting in poor truncating effect. Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a cable truncating device for electric power line construction is provided, with the expectation of achieving a more practical value purpose. Content of the Utility Model
