产品详情
A high voltage drop out fuse is a commonly used protection device for outdoor power distribution systems. It is designed to protect overhead lines, distribution transformers, and branch circuits from overload and short-circuit faults. Wishpower high voltage drop out fuse offers reliable insulation, stable operation, and convenient maintenance for medium-voltage distribution networks.
The product is generally composed of an insulating support, upper contact, lower contact, fuse tube, mounting bracket, operating ring, and fuse link. It is widely used for 10kV, 11kV, 15kV, 24kV, 27kV, and 33kV distribution systems.
Wishpower product advantages:
High-strength insulating support with reliable mechanical performance
Suitable for long-term outdoor operation in harsh environments
Clear drop-out indication for fast fault identification
Compact structure and easy installation on overhead lines
Suitable for transformer protection and branch line protection
Customizable voltage rating, current rating, and mounting dimensions
Core Features
Reliable Line Protection
The high voltage drop out fuse interrupts overload and short-circuit faults quickly, helping isolate faulty sections and reduce the impact on the power network.Visible Disconnect Point
After the fuse link operates, the fuse tube drops down and provides a clear visual indication of the faulted circuit.Excellent Insulation Performance
The product can be supplied with porcelain insulation or composite insulation to meet different outdoor application requirements.Easy Operation and Maintenance
Operators can use an insulated operating pole to open, close, or replace the fuse tube safely and efficiently.Wide Application Range
It is suitable for overhead distribution lines, branch circuits, distribution transformers, capacitor banks, and rural power grids.Strong Outdoor Weather Resistance
The fuse cutout is suitable for high temperature, low temperature, humidity, coastal areas, polluted areas, and strong UV environments.
Product Structure
The high voltage drop out fuse mainly consists of the following components:
Insulating Support
Provides mechanical support and electrical insulation between the live parts and the mounting bracket. Porcelain or composite insulation can be selected.Upper Contact Assembly
Connects with the upper end of the fuse tube and ensures stable electrical contact during normal operation.Lower Contact Assembly
Supports the lower end of the fuse tube and acts as the pivot point for the drop-out action.Fuse Tube
Contains the fuse link and drops down automatically after the fuse link melts under fault current.Fuse Link
Selected according to the rated current and protection requirement. It provides overload and short-circuit protection.Mounting Bracket
Used to install the fuse on a crossarm, pole, or support structure. Hot-dip galvanized steel is commonly used for corrosion resistance.Operating Ring
Allows safe manual operation using an insulated operating pole.
