Transformer bushing
12kV-363kV FRP Capacitive Transformer Bushing
The FRP capacitive transformer bushing is a new type dry transformer bushing possessing proprietary intellectual property right of our company, which adopts epoxy resin-impregnated FRP winding & solidifying system; the insulating layer is formed by spiral winding; the capacitive panel is formed by winding the semi-conductor conformal materials; the pure-solid capacitive cores which are formed through high temperature solidification are set at the intervals between alternate winding operations of insulating layer and capacitive panel; subject to use and assembly requirements; machining ways are adopted for expected shape and sizes; the connecting flanges are directly glued on the protection layer external to insulation of capacitive core; external insulation is directly injected on the surface of capacitive core, with the rubber shed injection molding technology. This bushing has a pretty good structural strength, simple structure and less sealed parts, free of maintenance.
The product possesses the features as follows:
a. The product is oil-free, porcelain-free, and gas-free solid, without filler and leakage, having great moisture-proof performance, and no maintenance is required;
b. With a large designed insulation margin, semi-conductor capacitive panel furthest enhances the discharge inception voltage, and there is no partial discharge during service;
c. The anti-flaming insulation materials have stable electrical performance, without decomposition and risk of burning and exploding;
d. The product has compact structure, small sizes and light weight, which is easy to be transported and can be installed in any direction;
e. The fiberglass has the winding operation improved, and the mechanics layer design optimized, with high anti-bending strength and high mechanical strength, which is also reliable when used at severe earthquake areas;
f. With perfect high and low temperature resistance performance, it used to be applied in electrostatic dust collector (+135℃) and super-conduction cable connector (+90℃ at one end, and -200℃ at the other end);
g. Silicon rubber compound coating has excellent anti-pollution flashover performance. It is self-cleaned, which can be used at heavy pollution area;
h. It possesses a long working life, with low cost against long-term service.
i.加工周期短，可根据用户要求进行特殊设计；
i. It has a short processing cycle, which can be specially designed according to user’s requirements.
