产品详情
The 35kV double-post windproof drop-out fuse is designed for medium- and high-voltage outdoor distribution systems. It is commonly installed on overhead distribution lines, transformer primary sides, and outdoor feeder branches. When overload or short-circuit faults occur, the fuse link melts quickly and the fuse tube drops down to provide a visible isolation point. With a reinforced double-post windproof structure, this product offers better stability under strong wind, vibration, and demanding outdoor conditions.
Key advantages include:
Stable double-post support structure
The double-post design improves mechanical stability and reduces movement caused by strong wind or vibration.Windproof design for outdoor service
Suitable for mountainous areas, coastal regions, open fields, rural networks, and other windy installation environments.Visible disconnection after operation
After fuse operation, the fuse tube drops down clearly, allowing maintenance teams to identify faulted sections quickly.Reliable long-term outdoor performance
The fuse can be supplied with polymer or porcelain insulation according to project requirements.Easy installation and maintenance
Compact structure and pole-mounted design help reduce installation time and maintenance difficulty.
Core Features
Suitable for 35kV distribution systems
Designed for 35kV overhead lines, branch feeders, and transformer protection.Strong wind-resistant performance
The double-post structure improves stability under wind load, vibration, and outdoor mechanical stress.Reliable fault interruption
During overload or short-circuit conditions, the fuse link operates and the fuse tube drops to isolate the faulty circuit.Excellent insulation performance
Polymer housing or porcelain housing options are available for different operating environments.Wide environmental adaptability
Suitable for standard outdoor areas, high-altitude regions, polluted areas, coastal zones, and windy locations.Effective sectional protection
Ideal for feeder branches, transformer primary protection, cable protection points, and overhead distribution networks.
Product Structure
A 35kV double-post windproof drop-out fuse usually consists of the following components:
Upper contact assembly: Connects to the line side and ensures stable current conduction.
Lower contact assembly: Supports the conductive circuit and allows fuse tube drop-out operation.
Fuse tube assembly: Holds the fuse link and drops down after fuse operation.
Double-post insulation support: Provides mechanical support and electrical insulation, available in polymer or porcelain type.
Mounting bracket: Used for pole-mounted or outdoor frame-mounted installation.
Windproof limiting structure: Improves the closed-position stability of the fuse tube.
Conductive terminals: Used for connecting overhead conductors or cable leads.
