1989年,日本一本杂志第一次向世界介绍一种损耗率仅为万分之五十的瓷介高压电容。 1990年,低损耗瓷个高压电容器首先在日本问世,几乎同时挤进了中国市场;大批外汇由这条渠道流向国外厂商的腰包。 1991年,中国将这种产品的开发列入“火炬”计划,并将其列入进口产品国产化重点项目。 In 1989, a Japanese magazine introduced to the world for the first time a porcelain dielectric high-voltage capacitor with a loss rate of only 50 per cent. In 1990, low-loss porcelain high-voltage capacitors were first introduced in Japan and almost simultaneously squeezed into the Chinese market; a large number of foreign exchange flows from this channel to foreign manufacturers. In 1991, China included the development of this product in the “Torch Plan” and listed it as a key project for localization of imported products.
