High-reliability, zero-leakage 110kV power transformer with advanced short-circuit withstand capability for utility and renewable energy applications.
Passed the National Transformer Test Center’s sudden short-circuit test on first attempt, confirming mechanical strength against electromagnetic forces during grid faults without core displacement or winding deformation.
All sealing components use die-cast construction validated via fluorescence, positive-pressure, and negative-pressure testing methods, eliminating oil seepage risks even under thermal cycling and vibration.
Eliminated traditional hanging-core design reduces mechanical stress points and maintenance requirements, enhancing long-term reliability while simplifying field inspection procedures.
Component-level acoustic engineering addresses noise generation at source, achieving sound levels below national limits through optimized core clamping, tank damping, and bushing isolation.
Fully enclosed production facility maintains constant temperature, humidity, and dust-free conditions, ensuring consistent insulation quality and preventing contamination during assembly.
Electromagnetic finite-element analysis validates winding clamping pressure and core support structure before production, ensuring mechanical integrity matches verified test performance rather than relying solely on empirical design rules.
Every die-cast sealing component undergoes triple verification (fluorescence penetration, positive-pressure hold, negative-pressure decay) to guarantee zero-leakage performance across all operating temperatures and pressure cycles.
Constant-temperature, humidity-controlled, and dust-free production environment prevents particulate contamination during core stacking and winding insertion, directly supporting low partial discharge and long-term dielectric stability.
Routine and type tests align with GB/T 1094 and IEC 60076 requirements, including lightning impulse, switching impulse, and induced voltage withstand; all qualified units include test reports traceable to National Transformer Test Center protocols.
