I. Overview 
 Drop fuse is the branch lines and distribution lines most commonly used distribution transformer short-circuit protection switch. It has an economic, easy to adapt to the outdoor environment and other characteristics, are widely used in distribution lines and distribution transformers as a side for equipment protection and investment, cut operating purposes. Distribution lines installed in the branch line to narrow the scope of power outages. Because there is a clear disconnect point, comes with flexible auxiliary contact and interrupter cover for division and rated load current. 
 Second, the use and implementation of standards 
 This product is used in 10-35KV distribution lines and branch lines one side of distribution transformers for overload and short circuit protection, division and rated load current. 
 The product model by JB/T8321 "high voltage fuse type weaving methods" provisions of the preparation, the product parameters by GB15166.3 "high voltage fuses Expulsion fuses" standards, the standards show the importance of clearly defined parameters with the configuration, according to JB/DQ2139-1986 "10-35KV outdoor high voltage drop fuse Interim technical conditions" amendment to the implementation of the requirements.
