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.
