High Voltage limit Current Fuse For Oil-immersed Transformer Protection

KEY WORDS:High pressure vacuum switch



The product can be used in system with AC 50Hz and rated voltage of 10KV, used togethe r with other protection electtic faciIities(such as loading switches). It can protect electtic transformers and other electtic faciIitles against overloading or circuit break. It is mainly used in American style box transformers as backup protection.
