Product Overview
The Wishpower HRGW-66kV windproof V-type drop-out fuse is used to isolate faults and protect electrical equipment in high-voltage distribution systems. When an overload or short-circuit fault occurs, the fuse element melts and the fuse tube drops automatically, creating a clear visible disconnection point for inspection and maintenance.
Compared with conventional drop-out fuses, the windproof V-type design offers better mechanical stability and improved anti-swing performance. It is especially suitable for windy areas, mountainous regions, coastal environments, and outdoor power lines exposed to vibration, humidity, and pollution.
Main advantages of Wishpower fuse cutouts include:
Suitable for 66kV outdoor high-voltage power systems;
Windproof V-type structure for stable fuse tube operation;
Reliable insulation and mechanical strength;
Clear visible disconnection after fuse operation;
Designed for transformer, overhead line, and pole-mounted equipment protection;
Easy installation and maintenance;
Suitable for harsh outdoor environments, including wind, humidity, pollution, and corrosion.
Core Features
Windproof V-Type Structure
The V-type support and windproof locking design reduce the risk of fuse tube instability caused by strong wind or vibration.Designed for 66kV Systems
The product is suitable for 66kV outdoor distribution lines, transformer branches, and substation feeder protection.Visible Isolation Function
After fuse operation, the fuse tube drops down automatically, providing a clear visual indication of the faulted section.Excellent Electrical Insulation
The insulation structure provides reliable withstand voltage performance, anti-pollution capability, and outdoor aging resistance.Stable Conductive Contact System
Reliable upper and lower contacts help reduce temperature rise and improve current-carrying stability.Easy Installation and Maintenance
The product is suitable for pole-mounted installation, cross-arm installation, and outdoor distribution line upgrades.Suitable for Harsh Environments
It can be used in windy areas, coastal regions, mountainous environments, polluted areas, and locations with large temperature variations.
Product Structure
The HRGW-66kV windproof V-type drop-out fuse usually consists of the following components:
Insulating Support: Provides high-voltage insulation and mechanical support. Polymer or porcelain insulation can be selected according to project requirements.
Upper Contact Assembly: Ensures stable electrical contact when the fuse tube is closed.
Lower Contact Assembly: Supports the fuse tube and acts as the pivot point during drop-out operation.
Fuse Tube Assembly: Contains the fuse element for overload and short-circuit protection.
Windproof V-Type Bracket: Enhances fuse tube stability and reduces movement under windy conditions.
Mounting Hardware: Used for pole, cross-arm, or bracket installation, typically with hot-dip galvanized anti-corrosion treatment.
Arc-Extinguishing Structure: Helps extinguish the arc during fuse operation.
Terminal Connectors: Provide reliable connection for incoming and outgoing conductors.
