Advanced Features
Premium Materials
Insulation components utilize high-aluminum C130 porcelain with grey, brown, or white glaze options. Metal caps are manufactured from dense ductile iron with magnetic particle testing, while pins are forged steel with hot-dip zinc coating.
Triple Shed Design
Special triple shed configuration provides superior electrical performance compared to standard fog-type insulators. This design also reduces wind force impact, enhancing transmission line safety in high-wind conditions.
Comprehensive Testing
Each unit undergoes routine tension load testing (50% of rated mechanical strength for 1 minute) followed by individual flashover testing. Batch sampling includes dimensional verification, temperature cycling, M&E failing load tests, puncture tests, and galvanization thickness analysis.
Applications
Suitable for suspension strings in high-voltage power transmission lines including 330kV, 400kV, and 500kV systems.
Quality Assurance & Competitive Advantages
HIVOLT U210BWP3 insulators feature excellent mechanical and electrical performance with 2-year quality guarantee. All units are individually tested to ensure defect-free performance. Custom designs and OEM manufacturing available based on technical specifications.
