Product Overview
The HGRW1-35/200A wind-resistant fuse cutout is engineered specifically for 35kV wind farm applications, installed on the high-voltage side of distribution lines or transformer branches. It serves dual roles: transmitting power while providing reliable overload and short-circuit protection, as well as safely interrupting rated load currents. Developed to address common wind farm challenges high-wind dislodgment and unstable operation, this device effectively prevents fault-free drops in demanding conditions, offering a stable and maintenance-friendly solution for harsh environments.
Product Features
◆Wind-Resistant Design: Reinforced insulator with a thickened central drawbar and precision-cast steel connections minimizes sway and displacement under high winds.
◆Dual-Contact Mechanism: Upper moving contact uses dual-point contact, lower moving contact employs reversible design, and static contacts combine pressure-lock and snap-fit modes for reliable connection.
◆High-Durability Materials: Composite insulators, stainless steel fasteners, and phosphor bronze switch contacts ensure corrosion resistance and long-term reliability.
◆Precision Engineered Components: Die-cast copper parts and glass fiber-wound tubes enhance mechanical strength and operational stability.
◆Enhanced Safety Structure: Double-contact surfaces and reinforced brackets prevent accidental disconnection and maintain alignment under external forces.
Product Advantages
◆Stable in Extreme Winds: Specialized design prevents unintentional drops, ensuring continuous operation in high-wind wind farm environments.
◆Low Maintenance: Robust construction and corrosion-resistant materials reduce servicing needs and extend product lifespan.
◆Easy Operation & Installation: User-friendly design simplifies field handling, mounting, and routine inspections.
◆Reliable Fault Protection: Effectively isolates overloads and short circuits, safeguarding transformers and distribution lines.
◆Adaptable to Harsh Conditions: Suitable for high-altitude, coastal, and other challenging environments with strong winds and temperature variations.
