33kv Drop out fuse is the most commonly used short-circuit protection switch for branch lines of distribution lines and distribution transformers. It has the characteristics of economy, easy operation, and strong adaptability to outdoor environments. It is widely used in 33kV distribution lines and the primary side of distribution transformers for protection and equipment switching operations. It is installed on the branch line of a 33kV distribution line, which can reduce the range of power outages. Due to its obvious disconnection point, it has the function of an isolation switch, creating a safe working environment for the maintenance section lines and equipment, and increasing the sense of security of maintenance personnel. Installed on distribution transformers, it can serve as the main protection for distribution transformers, so it has become popular in distribution lines and distribution transformers.
Product Detail
A 33kV drop out fuse cutout is an outdoor high-voltage protective device installed on overhead distribution lines or at the high-voltage side of distribution transformers. It provides reliable over-current, short-circuit, and overload protection, while enabling visible indication of fuse operation once a fault occurs.
Drop out fuse cutouts are widely used in utility networks and industrial installations for medium voltage distribution protection.
Our 33kV dropout fuse cutouts are available in:
33kV / 36kV rated voltage class
100A, 200A and 400A rated current options
