      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.
