Rockwill specializes in the design and manufacturing of 33kV oil immersed grounding transformers, engineered for reliable grounding protection in power systems. Our products comply with IEC and IEEE international standards, ensuring stable and safe operation of electrical networks.

Ang core ng transformer ay gawa sa high-quality cold-rolled oriented silicon steel sheets na may 45° full diagonal joints. Ang iron yoke ay maingat na pinapitil gamit ang through bolts, at ang mga core columns ay nakakabit gamit ang fiberglass tape. Ang surface ng core ay napapalit ng silicone resin adhesive para sa moisture protection at noise reduction.
Ang mga winding ay itinayo gamit ang high-quality copper conductors sa isang segmented cylindrical structure upang palakasin ang interlayer insulation. Ang vacuum drying technology ay ginagamit upang matiyak ang excellent electrical performance, mataas na mechanical strength, at minimal partial discharge.
Ang oil immersed grounding transformer ay may fully sealed tank na may corrugated fins para sa efficient heat dissipation, na nagbibigay-daan sa pag-iwas sa paggamit ng oil storage tank. Ang mga oil tanks ay naka-seal gamit ang oil-resistant rubber strips upang iwasan ang contact sa hangin, na nagpapanatili ng kalidad ng insulating oil at pana-extend sa lifespan ng transformer. Compact footprint, aesthetic appearance, at maintenance-free design ay key benefits.
Kasama ang pressure relief valves, gas relays, at oil level gauges para sa real-time monitoring ng kondisyon ng langis. Ang temperature control devices ay sumusuporta sa remote transmission, na nagbibigay ng convenient supervision sa operating temperature ng transformer.
