Abubuwan Fanni & Benefits
Advanced Zigzag Winding Design – Unlike conventional transformers, Rockwill’s Z-Type configuration ensures zero-sequence flux circulates within the core, minimizing impedance and enhancing grounding performance.
Full-Capacity Arc Suppression Support – Compatible with 90-100% rated capacity arc suppression coils, far exceeding the 20% limit of standard transformers.
Dual-Purpose Functionality – Optional secondary winding allows the transformer to supply station power, reducing the need for additional equipment.
Dry-Type, Cast Resin Construction – Maintenance-free, flame-resistant, and suitable for harsh environments.
High Efficiency & Reliability – Engineered for stable operation under fault conditions, preventing magnetic saturation.
IEC 60076 Compliant – Manufactured to international standards for global reliability.
Me Yadda Ake Zaɓe Rockwill?
Rockwill grounding transformers sun bayar da superior performance, safety, and cost savings by combining neutral grounding and auxiliary power supply in a single unit. Their optimized design ensures enhanced system protection, reduced downtime, and lower installation costs—making them the ideal choice for modern power systems.
