EC Insulator Jiangxi Co., Ltd. is one of the most reliable manufacturers and suppliers of pole mounted dropout fuse in China. With abundant experience, we are committed to offering high quality custom service. Please feel free to wholesale premium pole mounted dropout fuse made in China here from our factory.
Product Overview
A pole mounted dropout fuse is a safety device installed on overhead power poles. It protects distribution lines and pole mounted transformers from damage caused by overload and short circuit. When a fault occurs, the internal fuse element melts, and the fuse tube drops down to create a visible open circuit. This allows the faulty section to be isolated quickly and reduces the risk of further damage to downstream equipment.
This pole mounted dropout fuse is designed for medium voltage overhead distribution systems. It consists of a strong insulating body, precision metal parts and a reliable dropout mechanism. The pole mounted dropout fuse delivers stable performance under normal outdoor operating conditions. Each unit is fully manufactured and tested in our workshop before shipment. Our products are supplied to power distributors, engineering contractors and project buyers worldwide.
Technical Data
We offer standard pole mounted dropout fuse models for medium voltage overhead distribution projects. The available ratings include 15kV, 27kV and 38kV. Customers can also select 100A or 200A according to their project requirements. These ratings are commonly used in different distribution network designs.

The breaking capacity of the fuse is matched to the fault level of the protected circuit. When a short circuit occurs, the fuse operates within a controlled time and interrupts the fault current. This helps prevent serious damage to transformers, cables and other power equipment.

Usage Sites
The pole mounted dropout fuse is widely used in overhead distribution systems. It can be installed on utility poles to protect main lines, branch lines and pole mounted transformers. Typical applications include rural electrification projects, urban distribution circuits, industrial power supply routes and commercial area networks.
It is suitable for locations where simple, reliable and visible protection is required. Since the dropped fuse tube can be seen from a distance, maintenance teams can identify the fault more quickly. This makes it practical for both urban and remote overhead distribution projects.
Many engineering contractors and power distributors use this device as primary protection for medium voltage circuits. It is often selected for its simple structure, easy maintenance and reliable performance in outdoor power networks.
