33kv Polymer Dropout Fuse Cutout

Product Description

Product Description

A fuse cutout is an electrical protection device used in overhead line systems to prevent distribution transformers from being damaged by surges. The working principle of these devices is to connect the fuse to the series of the transformer feeder cable. The connection is through a hinged tubular fuse, in this way the fuse is fixed in position on the cut body. If the link melts and separates under over-current conditions, the fuse holder will drop freely under its own weight, rotate to the hinge, and hang vertically, making its state clearly visible. Most fuse cutout is designed with a metal ring on the fuse holder. When maintenance and repair personnel need to work on the transformer, the fuse can be manually disconnected.

Features::

Applications:

- Light weight and easy installation
- Reliable fault protection
- Perfect drop out action
- Good hydrophobic property
- Higher creepage distance

- Protection for overhead distribution line branches in urban and rural areas
- Short-circuit and overload protection for primary side of distribution transformers
- Matched with outdoor pole-mounted distribution equipment
- Line protection for small substations and rural grid renovation projects
- Isolation and protection for outdoor power terminal equipment
