• The appearance forms and sizes are like the blue prints.
• They can be plugged into outlets easily and are perfect structures in smooth electric contact.
• Pin insulting materials of insulting plugs of good brand types are nylon resin of good thermal resistance. 

• Insulation resistance - As DC 500V insulation testers, in case of measuring insulation resistance among different polarities' filled

    metal parts, unfilled metal parts, and a plug body, it is 100MΩ and more.
• Withstanding voltage - When AC 4000V is given at a measured part for a minute, there is no problem.
• Heat resistance - When the product is left at 80℃ for 12 hours, ignition, expansion, deformation, and other harmful problems do not

     happen.
