产品详情

The 24kV–27kV drop-out fuse is a widely used protective device for medium and high voltage outdoor distribution networks. It is mainly applied to overhead distribution lines, pole-mounted transformers and outdoor power equipment for short-circuit and overload protection. Wishpower 24kV–27kV drop-out fuse is designed with reliable insulation, conductive contacts and fuse tube structure. When a fault current occurs, the fuse element melts and the fuse tube drops down, providing visible fault indication for fast inspection and maintenance.

Wishpower 24kV–27kV drop-out fuse is suitable for outdoor distribution systems with rated voltages from 24kV to 27kV. It can be installed on distribution line branches, transformer primary sides, cable terminals and pole-mounted distribution equipment. According to project requirements, Wishpower can provide polymer housing, porcelain housing, expulsion type and load break type fuse cutouts for different operating environments.

Main advantages include:

  • Suitable for 24kV and 27kV medium and high voltage distribution networks.

  • Provides short-circuit and overload protection for distribution systems.

  • Drop-out structure offers clear visual indication after fuse operation.

  • Polymer and porcelain insulation options are available.

  • Designed for outdoor service under rain, UV exposure, pollution and temperature variation.

  • Compact structure supports easy installation and maintenance.

  • Ideal for pole-mounted transformer protection and overhead line protection.

Key Features

  1. Reliable Fault Interruption
    The fuse isolates faulty circuits when short-circuit or overload current occurs, helping reduce equipment damage and service interruption.

  2. Visible Drop-Out Indication
    After fuse operation, the fuse tube drops down clearly, allowing maintenance teams to identify the fault position quickly.

  3. Outdoor Environmental Performance
    The product is suitable for rural networks, urban distribution systems, industrial power supply and outdoor substations.

  4. Multiple Structure Options
    Polymer housing, porcelain housing, standard expulsion type and load break type designs can be selected according to the project.

  5. Easy Maintenance
    Fuse links and fuse tubes can be replaced conveniently, reducing maintenance time and operating cost.

  6. Transformer Protection Compatibility
    It is commonly used on the high voltage side of distribution transformers to isolate transformer faults and protect the main line.

Product Structure

The 24kV–27kV drop-out fuse generally consists of the following parts:

  • Insulating Support: Polymer insulator or porcelain insulator for electrical insulation and mechanical support.

  • Upper Contact Assembly: Connects the incoming conductor and ensures stable current transmission.

  • Lower Contact Assembly: Supports the fuse tube and forms a reliable conductive path.

  • Fuse Tube: Holds the fuse link and drops down after fuse operation.

  • Fuse Link: The core protection element selected according to rated current and protection requirements.

  • Mounting Bracket: Used for pole-mounted, crossarm or outdoor structure installation.

  • Arc Extinguishing Structure: The expulsion fuse tube helps extinguish the arc during fault interruption.

  • Operating Ring: Allows operation with an insulated hot stick.
