·       There are fire retardant components, discharge components as well as self-protection components in the internal of capacitor.
·       電容單元的結構采用極板凸出設計,可基本消除電阻損耗,提高瞬時過電流能力。極間介質為易于浸漬的表面粗化聚丙薄膜,特別提高了大容量電容器的可靠性。
·       The structure of capacitor unit adopts the design of protruding electrode plate to basically eliminate the resistance loss and enhance the capacity of instantaneous current. The interelectrode dielectric adopts the polypropylene film with surface coarsening which is easy to impregnate so as to enhance the reliability of high-capacity capacitor.
·       作為電極的鋁箔的邊緣采用折邊鋁箔結構,邊緣呈圓弧形,改善場強分布,最大邊緣場強與平均場強之比由6倍降低至2倍左右,這樣通過消除極板邊緣毛刺來消除高場強點,能設計比一般高的電場強度,減低了電容器的損耗,降低了電容器局部放電的幾率,從而更提高了電容器的絕緣可靠性。
·       The aluminum foil used to be electrode and its edge adopts fold and curvic structure, so as to improve the distribution of field intensity (FI), and reduce the ratio of Maximum Edge FI Vs Average FI from 6 to 2, in this way, eliminate the higher FI points by eliminating the burr on the edge of electrode plate, and be able to design and produce higher field intensity than the ordinary one. In addition, reduce the loss of capacitor and the probability of partial discharge, so as to enhance the insulation reliability of capacitor.
·       作為浸漬劑的絕緣油具有優良的介電性能,化學性能穩定,不含氯或氯化聯苯,能完全生物降解,對環境無污染,凝點低,黏度小,低溫性能好,對局部放電產生的氣體有很好的吸收能力,燃點高,具有出色的耐受過電壓能力。
·       As the impregnant, the insulating oil is provided with the following features, such as excellent dielectric performance, stable chemical performance, non-chlorine or chlorinated biphenyl, complete biodegradation, non-pollution, low condensation point, low viscosity, excellent performance under low temperature and absorption capacity for the gas which is produced by partial discharge, high fire point, excellent capability of over-voltage withstanding.
