In what way is a screwdriver insulated?
螺丝刀是如何做到绝缘的？
VDE screwdrivers feature insulation made from plastic that extends all the way to the blade. This reduces the risk of an electric shock. There are also screwdrivers that are specially designed for use in electrical installations and are approved for work on live parts. They are labeled with the VDE symbol.
