This article introduces a new type of flexible inorganic mineral insulated power cable, whose rated voltage is 0.6/1 KV. Based on user requirements, test criteria and the performance index of the cable and structure analysis, we have designed and chosen the structure of new type of flexible inorganic mineral insulated power cable, and tried to make trial production samples and tested it, which has verified the rationality of the structure and the its feasibility and the combination of the fire test standards. Meanwhile, in terms of indicators, such as the fire test results stability performance of the the article compared the new type of flexible inorganic product, installation and maintenance projects and etc., mineral insulated cable with Magnesium oxide mineral insulated cable and inorganic mineral insulated metal sheath cable, and it showed strong superiority of new type of flexible inorganic mineral insulated power cable developed by ourselves. This kind of product could replace the traditional mineral insulatin~ refractory cable with good potential market prospect.
