The HGRW1-35 drop-out fuse is a wind-resistant 35kV outdoor high-voltage protection device, specially designed for areas prone to strong wind, salt fog, or high altitude. It is widely used on overhead lines and pole-mounted transformers in utility and industrial networks.
HGRW1-35 uses a reinforced hinge and locking mechanism to maintain stability during strong winds. The drop-out mechanism provides visible disconnection upon fuse blow, ensuring line safety and maintenance efficiency. Suitable for areas up to 4,000m altitude and wind zones up to Class 9.
Key Features:
Designed for 35kV systems, max 100A fuse links
Wind-resistant metal frame and porcelain insulator
Quick visual fault detection via fuse drop-out
Manual reset and easy link replacement
Ideal for coastal, plateau, or storm-prone regions
