Electrical Insulation Materials

    1. Cotton Fabric Reinforced Phenolic Laminate SheetCotton fabric reinforced phenolic laminate sheet is made by heating and pressurization after cotton fabric immersing into phenolic resin. It has good electrical and mechanical properties under normal conditions. Thus it is widely applied in machinery, motor and electrical equipment as insulation structure parts and even in transformer oil as well.
    1. Paper Reinforced Phenolic Laminate SheetDue to low dielectric loss of paper, it is often used for making insulation parts of transformer and electric reactor. Paper reinforced phenolic laminate sheet is often used as the work surface of operating table and NMR equipment in medical equipment, as a result of low loss of X-ray and electromagnetic wave passing through paper reinforced phenolic laminate sheet.
    1. Fiberglass Epoxy Laminate SheetFiberglass epoxy laminate sheet is under high-temperature and high-pressure conditions after fiberglass fabric immersing into epoxy. It has higher mechanical strengths and better electrical properties than laminate sheet and fabric plate, thus it has wide applications.
    1. Heat Resistant Laminate SheetF890H has good electrical apparatus insulation performance with CTI index 600M, halogen free and inflaming retarding. Temperature class is H. Its long-term working temperature is over 180℃. Thus it can be used for H-class high-temperature motor and transformer which have higher requirements for environmental protection and inflaming retarding, such as rail vehicles, especially high speed train.
    1. Electrically Conductive Laminate SheetF889 electrically conductive laminate sheet has good mechanical strength, heat resistance and magnetic conductivity. It is usually made for slog wedge of large motor. Placed in the magnetic slot and wedge of motor, it can lower the temperature rise of motor and improve working efficiency and its service life.
    1. Glass Fiber Reinforced Epoxy SheetAs a result of adoption of glass fiber instead of glass, F876 glass fiber reinforced epoxy sheet has similar internal properties and it is highly suitable for making insulation screw, bolt and nut. It is usually used for insulation structural parts of H-class motor and electric equipment.
    1. Semi-conductive Glass Epoxy Laminate SheetF884 semi-conductive glass epoxy laminate sheet has anti-corona features, which is used as anti-corona materials in slot of large motor. It can also be used as non-metallic structural parts under high-temperature conditions.
    1. Glass Cloth Reinforced Melamine Laminate SheetIt has good arc resistance, anti-creep tracking and inflaming retarding. It can be used as structural parts in electric equipment that needs arc resistance and surface stain-resistance.
    1. Fiberglass Reinforced Benzoxazine Laminate SheetAs a heat resistant and inflaming retarding insulation sheet, it has good electrical performances and can maintain stable mechanical strength under temperature rising conditions. Meanwhile, it has good inflaming retarding and wear-resistance performances, which is the best option for halogen-free and inflaming retarding requirements.
    1. Fiberglass Reinforced Silicone Laminate SheetFiberglass reinforced silicone laminate sheet has relatively high mechanical strength, arc resistance, heat resistance and long-term working temperature over 180℃. It is applicable to be made as slot wedge and cushion block in H-class high-temperature motor and high-insulation structural parts for electrics. It is especially suitable for insulation parts that has dual requirements of heat resistance and arc resistance.
    1. Cotton Fabric Reinforced Phenolic RodCotton fabric reinforced phenolic rod is cylindrical laminate sheet that is made by special-purpose cotton fabric immersing into phenolic resin, through drying and rolling, and then hot-stamping in molds. It has good mechanical strength and certain insulation properties.
    1. Glass Epoxy Molded RodGlass epoxy molded rod is cylindrical laminate sheet that is made by electrical glass immersing into epoxy resin, through drying and rolling and then hot-stamping in molds. It has good mechanical and electrical performances, especially good humidity-resistance performance. Optional models include 3840, 3841F, 3842, EPGC41, EPGC42, EPGC43.
    1. Paper Reinforced Phenolic TubePaper reinforced phenolic tube is hard tubular insulation laminate sheet that is made by insulating paper with one side coated by phenolic resin through drying and rolling. Optional model is 3520. 3520 paper reinforced phenolic tube has relatively high dielectric performance and certain mechanical strength. It is suitable for insulation structural parts of electric equipment in dry conditions and transformer oil.
    1. Cotton Fabric Reinforced Phenolic TubeCotton fabric reinforced phenolic rod is suitable for insulation structural parts of electric equipment under dry conditions and in transformer oil. 3526 cotton fabric reinforced phenolic rod has good machining processing, damping and wear-resistance performance. It is usually used in electric equipment of large machines.
    1. Glass Reinforced Epoxy TubeGlass reinforced epoxy tube is used as insulation structural parts of electric equipment in dry environment and transformer oil, which is often used in anti-corrosion and solvent resistance tubes. 3640 and F815.3 glass reinforced epoxy tubes also have relatively high mechanical strength, heat resistance and dielectric properties. It can be used in transformer oil.
