Condenser bushing capacitance borders of the bases with adhesive tape manufacture, high mechanical strength, can be mounted at any angle, simple anti-moisture performance good insulation casing, structure and maintenance, no need for casing, the lower borders of the bases can also be turned into a short tail style, reduce its size. The disadvantage is that at high voltage and high-grade materials and process requirements must borders, foursquare is not easy to eliminate the gap, resulting in partial discharge voltage is low. Since the tape condenser bushing high dielectric loss and partial discharge voltage and low pfa insulating sleeve, it has gradually been replaced by paper Capacity bushing. The use of oil-paper capacitors for the bases, and generally have lower porcelain pvc insulated casing, the lower part of a larger size, more sensitive to moisture, high sealing requirements; the advantages of an insulating material and workmanship easy to solve, a small dielectric loss, good partial discharge performance. Since the 1970s, China has been widely used 110 to 500 kV EHV oilpaper condenser bushing. 1980s, China has developed a plastic impregnated paper casing, the capacitance insulating paper into a heart-sons after the borders of the bases is a synthetic resin vacuum impregnation ptfe insulated casing, and then by heat curing treatment. The performance advantages of both tape and paper Capacity-style casing. Bushings as an insulating material. Is a general term for electrical material in glass fiber insulation casing, PVC casing, thermal casing, such as oil or gas as an insulating medium, generally made transformer bushing or circuit breaker casing, commonly used in the 35 kilovolt voltage level. Composite bushing conductor cavity is filled with porcelain suite of transformer oil, from the radial insulation. When the voltage exceeds 35 kV when the conductor insulation tube or sleeve in the cable package to enhance insulation. Composite insulating sleeve cable type conductor structure through two and a guide rod. Through the use of cable type transformer cable leads directly through the casing for easy installation. When the current is greater than 600 security work, wearing cable-type structure is mounted is more difficult, the general guide rod structure. Condenser bushing by the capacitor bases, and porcelain, metal accessories and conductors. Mainly used for EHV transformers and circuit breakers. An upper portion in the atmosphere, in the lower part of the tank. Condenser bushing capacitance heart sons as internal insulation, porcelain sets as external insulation, but also play a protective role in heart sons capacitance. Porcelain surface electric field by the internal borders of the bases of the equalizing effect of capacitance and distribution, thus improving the electrical insulation sleeves. Metal accessories intermediate connecting sleeve (flange), cover, equalizing ball. Conductor cable or a rigid pipe. pfa insulating sleeve, insulating sleeve, the cap insulating sleeve (view) provided by the Dongguan City, the crown plastic products Limited.
