Product Overview
1. Product Overview
Wishpower 12kV–15kV drop-out fuse cutouts are used for overload protection, short-circuit protection and visible isolation in medium-voltage distribution networks. The product can be supplied with polymer insulation or porcelain insulation according to different project requirements and operating environments.
Key advantages include:
Suitable for 12kV, 15kV and similar medium-voltage distribution systems;
Designed for outdoor overhead lines, pole-mounted transformers and distribution feeders;
Clear drop-out indication after fuse operation, making fault location easier;
Polymer type offers lightweight construction and excellent pollution resistance;
Porcelain type provides stable mechanical strength and long-term aging resistance;
Works with fuse links to protect transformers, lines and distribution equipment;
Compact structure, easy installation and convenient maintenance.
2. Core Features
Reliable Overcurrent Protection
When short-circuit or overload faults occur, the fuse link melts and the fuse tube drops out, creating a visible open point for safe isolation.Excellent Outdoor Performance
The fuse cutout is designed for outdoor service with good resistance to UV, moisture, pollution, corrosion and temperature variation.Visible Fault Indication
The drop-out action provides a clear visual indication, helping maintenance teams identify the faulty section quickly.Easy Installation and Maintenance
Its simple structure allows easy pole mounting, fuse link replacement and routine inspection.Multiple Insulation Options
Polymer housing and porcelain housing options are available to meet different market requirements, environmental conditions and budget levels.Suitable for Distribution Network Upgrades
The product can be used as a protective device in medium-voltage feeder systems to improve sectional protection and fault isolation.
3. Product Structure
A 12kV–15kV drop-out fuse cutout normally consists of the following components:
Insulating support: Polymer or porcelain insulator used for electrical insulation and mechanical support.
Upper contact assembly: Connects the incoming line and ensures reliable conductivity when the fuse tube is closed.
Lower contact assembly: Supports the lower end of the fuse tube and enables drop-out operation after fuse melting.
Fuse tube: Holds the fuse link and drops out when the fuse operates.
Fuse link: Selected according to rated current and protection requirements.
Mounting bracket: Used for pole, cross-arm or outdoor structure installation.
Terminal connectors: Provide reliable connection with conductors or cable leads.
Arc-extinguishing structure: Helps interrupt the arc during fuse operation and improves switching safety.
