Product Overview
Ang 35kV oil-immersed earthing transformer ni Rockwill mahimong maghatag og reliable nga neutral grounding point sa medium-voltage networks diin dili mao ang direct grounding. Gigisahan niini ngadto sa zig-zag winding configuration, kini nga 3-phase transformer nag-siguro sa optimal nga zero-sequence impedance, efektibong limitahan ang ground fault currents ug stabilizing transient overvoltages.
Ang iyang robust nga oil-immersed construction nag-siguro sa long-term insulation reliability ug thermal performance sa outdoor environments.
Key Features
Zig-Zag Winding: Nag-enable sa controlled neutral grounding ug effective nga zero-sequence current flow para sa protective device coordination.
High Insulation Performance: Nag-comply sa 35kV-class insulation levels ug withstand voltage standards.
Efficient Core Design: Gihimo sa cold-rolled grain-oriented silicon steel aron mapabag-o ang core losses ug no-load current.
Copper Windings: Ang oxygen-free copper nag-siguro sa gipangutana ang winding losses ug superior short-circuit resistance.
Fully Sealed Tank: Maintenance-free samtang may anti-corrosion surface ug integrated oil conservator (if required).
Standardized Manufacturing: Gibuhat sumala sa IEC 60076, IEEE, ug customer-specific utility codes.
Typical Applications
Medium-voltage distribution systems (33/35kV class)
Renewable energy substations (solar, wind)
Isolated generator grounding systems
Utility ug industrial MV feeders requiring neutral grounding
Protection system grounding via NGR (Neutral Grounding Resistor)
