How Does a Wire Stripper Work?
Wire strippers are designed to provide a clean and precise cut without damaging the underlying wire. The stripping action is made possible by a set of sharp blades that grip the wire insulation and pull it off. When you place the wire into the jaws of the stripper, you apply force by squeezing the handles, which presses the cutting blades against the insulation.
Mechanism of Action
Wire strippers work on the principle of cutting the insulation without applying enough force to damage the wire beneath. Some wire strippers are manual, requiring the user to adjust the blade setting based on the wire’s gauge, while others may be automatic, adjusting themselves to the appropriate gauge.
The blades of the stripper are specifically designed to match various wire sizes, ensuring that the tool strips the insulation without nicking or damaging the wire itself. The cutting action is designed to separate the insulation without compromising the quality of the copper or aluminum wire.
