Description:

The major insulation of fiberglass capacitor bushing is capacitor core. Pure solid capacitor core is made by solidifying alternatively wound and interval arranged insulating layer (made by intersecting and superimposing winding imported high-insulation fiberglass impregnated with ultra-low viscosity high-temperature-resistant epoxy resin by microcomputer control winding equipment) and capacitor screen (made of semiconductor adaptive materials) in high temperature. Coupling flange is made of high-strength aluminum alloy. Umbrella skirt is injected at one time with silicon rubber on the surface of capacitor core to form an organic integral with the capacitor core; high strength porcelain umbrella skirt may also be installed, epoxy resin is filled between porcelain bushing and capacitor core in the vacuum casting mode.

a. 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;

b. The partial discharge starting voltage has been improved greatly due to the large insulation design margin and semiconducting materials as the capacitor screen;

c. Inflaming retarding insulating materials with stable electrical performance and without decomposition, combustion and explosion hazard;

d. Compact structure, small volume, light weight, convenient for transportation, may be installed at any angle;

e. 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;

f. Excellent high and low temperature resistant performance, maximum +145℃ and -200℃;

g. The products with silicon rubber compound shell may be used to the heavy polluted area for their excellent anti-fouling property;

h. Long performance life and low longtime running cost;

i. Production period is short; the products may be designed specially according to the users' requirements;
