The major insulation of fiberglass dry-capacitance transformer bushings is capacitor core.Pure solid capacitor core is made by solidifing alternatively wound and interval arranged insulating layer(made by winding,inntersecting and superimposing high-insulation fiberglass immersed in ultra-low-viscosity high-temperature-resistant epoxy resin by microcomputer control winding equipment according to geodesic) and capacitor screen(made of semiconductor adaptive materials)in high temperature.Coupling flange is made of high-strength aluminum alloy,which is cemented with capacitor core as a whole.Creepage extenders are injected and shaped with silicon rubber noce on the surface of capacitor core to be an organic integrity with the capacitor core.

    1.It is unnecessary to adopt special repair and maintenance for the products as they belong to the oil-free and pure-solid major insulation structure products;
    2.The partial discharge starting voltage has been improved greatly due to the large insulation design margin and semiconducting materials as the capacitor screen;
    3.Inflaming retarding insulating materials with stable electrical performance and without decomposition without combustion and explosion hazard;
    4.Compact structure,small volume,light weight,convenient for transportation,maybe installed at any angle;
    5.The products are especially suitable for the heavy earthquake regions for their reinforced fiberglass winding,optimized dynamic laying design,high bending strength and excellent mechanical performance;
    6.Perfect high and low temperature resistant performance,ranging from+155ºC to -200ºC;
    7.The products with silicon rubber compound shell maybe used to the heavy polluted area for their excellent antifouling property;  
    8.Long performance life and low long time running cost;
    9.Production period is short;the product may be designed specially according to the users requirements;
    10.High-strength enamel creepage extenders may also be available for the customer;
    11.Bushing maybe equipped with intelligent devices theat are used for the on-line insection of bushing insulation state,so as to meet the requirements of smart power grid.
