Description

technical field [0001] The invention relates to the field of power equipment, in particular to a power engineering construction tool box and a preparation method thereof. Background technique [0002] The power engineering construction tool box is used to hold the power engineering construction tools. There are many kinds of materials for the tool box, the common ones are plastic, injection molding, blow molding, etc. In electric power construction work, in order to ensure operational safety and reliability of power supply, power tools are widely used. Power tools are collectively referred to as power engineering construction safety operation tools, live working tools and insulation protection tools, usually including insulating gloves, insulating boots, ground guns, electroscope pens, and insulating rods. The insulation performance of damp or polluted power tools will be reduced, which will seriously endanger the life safety of workers and the operation safety of power gri...
