    Theinsulating materialmainly refers totheisolationchargedorpotentialcurrentconductoraccording tothepredetermineddirection offlow.Commonly usedinsulating materialscan be divided intoinorganicinsulating material,organicinsulationmaterial andhybridinsulation material.Insulation manufacturingplantnow producesmost of theorganicmaterial,itsheat resistance,mechanical strength andlife expectancyis much lowerthanthemetal material.

       Aninsulating materialtypes and models

     Anelectricalinsulating materialdividedintothree categories:gas, liquid,solid

       Twosolidinsulating materialsaccording to theirapplicationorprocesscharacteristicscanbedivided intosix categories:


        1)paint,resinandadhesiveclass

        2)impregnated fiberproductsclass

        3) Thelaminatecategory

        4)pressureplastic

        5)micarelated products

        6) film,adhesive tape andcomposite productsclass


        Twokey performance indicatorsofsolidinsulating materialshave the following:

        Abreakdown strength.

        (2)insulation resistance.
     
        (3)heat resistance.

        Viscosity,solidcontent,acid value,drying time andgeltime.

        (5)mechanical strength.Accordingtothe specific requirementsofvarious insulating materials,the corresponding provisions oftensile, compressive, flexural, shear,tear resistance,impact resistanceand otherstrengthindicators.
