HPRWG2-35 High Voltage Fuse – Reliable Protection for 35kV Outdoor Systems

Current-Limiting Drop-Out Fuse for Distribution Transformers and Overhead Lines

The HPRWG2-35 High Voltage Fuse is engineered for outdoor overhead systems operating at 35kV nominal voltage, offering fast and reliable fault interruption for transformers, capacitor banks, and feeder lines. As a drop-out type expulsion fuse, it combines ease of installation with high arc-extinguishing capability, minimizing damage to downstream equipment and ensuring system continuity.

Ideal for medium-voltage rural and industrial distribution networks, the HPRWG2-35 is fully tested to GB 15166.3 and IEC 60282-2, with proven performance in both temperate and high-humidity climates.
