Description

A secondary cable stripper

Technical field

The invention relates to a cable laying auxiliary tool, in particular to a secondary cable stripper.

Background technique

Secondary cables play an important role in the substation automation system. Equipment operation, signal collection and transmission are all inseparable from secondary cables. Cable stripping is a necessary process in the secondary cable access system. Currently, most of the operations are performed manually using simple tools. That is, the operator holds the cable with one hand for horizontal positioning, aligns the hand-held tool with the center of the cable, and strips off the cable insulation layer. , use diagonal pliers to peel off the metal armor layer. This method often causes: 1. When the operator holds the cable with one hand for horizontal positioning, the cable positioning is unstable, and the operator is highly focused, which is time-consuming and laborious; 2. Stripping along the direction When cutting wires, it is necessary to adjust the direction of the tool at all times and always keep the tool centered. At this time, the tool and the cable insulation layer are easy to slip and injure people, which affects the wire stripping efficiency; 3. When using diagonal pliers to peel off the metal armor layer, the diagonal pliers need to be The metal armor can be effectively peeled off only after being stuck in multiple times. It can easily slip off, injure people, and damage cables.
