Product Overview
Ang 35kV na oil-immersed earthing transformer ng Rockwill ay espesyal na disenyo para sa pagbibigay ng maasahang neutral grounding point sa mga medium-voltage networks kung saan ang direct grounding ay hindi available. May disenyo ng zig-zag winding configuration, ang 3-phase transformer na ito ay nagse-set ng optimal na zero-sequence impedance, na effectively limits ang ground fault currents at stabilizes ang transient overvoltages.
Ang matibay na oil-immersed construction nito ay nag-uugnay ng long-term insulation reliability at thermal performance sa outdoor environments.
Key Features
Zig-Zag Winding: Nagbibigay ng controlled neutral grounding at effective zero-sequence current flow para sa protective device coordination.
High Insulation Performance: Sumusunod sa 35kV-class insulation levels at withstand voltage standards.
Efficient Core Design: Gawa sa cold-rolled grain-oriented silicon steel upang bawasan ang core losses at no-load current.
Copper Windings: Ang oxygen-free copper ay nagse-set ng reduced winding losses at superior short-circuit resistance.
Fully Sealed Tank: Maintenance-free na may anti-corrosion surface at integrated oil conservator (if required).
Standardized Manufacturing: Inilalayo ayon sa IEC 60076, IEEE, at customer-specific utility codes.
Typical Applications
Medium-voltage distribution systems (33/35kV class)
Renewable energy substations (solar, wind)
Isolated generator grounding systems
Utility and industrial MV feeders requiring neutral grounding
Protection system grounding via NGR (Neutral Grounding Resistor)
