Oil-Immersed Distribution & Power Transformers
AIKEY S11, S13, S20, and S22 series three-phase oil-immersed transformers feature fully sealed corrugated tanks that eliminate the need for an oil conservator. The corrugated fins expand and contract with temperature changes, completely isolating the dielectric oil from atmospheric moisture and oxygen, extending operating life beyond 30 years with zero periodic oil filtration.
Standard Technical Parameters (10kV & 20kV Series Comparison)
| Series Model | Rated Capacity (kVA) | Voltage Combination | No-Load Loss Reduction | Impedance (%) | Cooling & Fluid |
|---|---|---|---|---|---|
| S11 Series | 30 – 2500 kVA | 10(20) / 0.4 kV | Standard Low Loss baseline | 4.0% – 4.5% | ONAN / Mineral Oil |
| S13 Series (Eco) | 30 – 2500 kVA | 10(20) / 0.4 kV | 30% lower than S11 | 4.0% – 4.5% | ONAN / Mineral Oil |
| S20 Series (Grade 1) | 50 – 2500 kVA | 10(20) / 0.4 kV | Grade 1 Energy Efficiency Standard | 4.5% – 5.0% | ONAN / High Flashpoint Oil |
| SZ11 / SZ13 Series | 500 – 31,500 kVA | 35 / 10(6.3) / 0.4 kV | On-Load Tap Changing (OLTC) | 6.5% – 8.0% | ONAN / ONAF Forced Air |
Cast Resin & Specialty Dry-Type Transformers
AIKEY SCB10, SCB13, SCB14, and SCB18 cast resin dry transformers are encapsulated in pure epoxy resin under high vacuum with quartz sand filler. Featuring zero fire risk, self-extinguishing flame resistance, and moisture impermeability, they are engineered for indoor commercial skyscrapers, data centers, airports, and urban metro traction substations.
Dry-Type Transformer Specifications & Applications
| Category | Typical Models | Rated Voltage | Key Advantages | Primary Deployment |
|---|---|---|---|---|
| Resin Cast Dry Transformer | SC(B)10, SC(B)13, SC(B)18 | 10kV, 20kV, 35kV | Flame-proof, zero risk of explosion, low partial discharge, maintenance-free. | Hospitals, high-rises, airports, data centers |
| Air-Insulated Open Dry | SG(B)10 Series | 10 / 0.4 kV | NOMEX® insulation paper, non-toxic, recyclable, 220°C thermal limit. | Chemical plants, mining, nuclear environments |
| Metro Traction Rectifiers | ZSCB13 Series (12/24-Pulse) | 10kV / 35kV to 1.18kV | High harmonic withstand, multi-phase shifting, high overload capacity. | Subway, light rail, urban transit DC power |
| VFD Inverter Transformers | SMSG Multi-Winding | 3kV – 10kV | Multiple secondary windings for harmonic elimination in heavy drives. | Smelting drives, mine hoists, high-power pumps |
Solid Insulated Switchgear (SIS 6-10kV / 12kV)
The AIKEY Ultima Solid Insulated Switchgear is the next-generation green distribution solution. By embedding the vacuum circuit breaker, disconnector, and busbars into solid epoxy resin pole modules, it completely eliminates SF6 gas. Resistant to extreme cold winters down to -40°C (preventing SF6 liquefaction) and desert heat up to +45°C with zero gas pressure decay.
Functional Modular Cell Types & Configurations
| Cell Designation | Functional Unit | Rated Current | Breaking Capacity | Typical Application |
|---|---|---|---|---|
| Unit V / V(D) | Vacuum Circuit Breaker Cell | 630 A / 1250 A | 20 kA / 25 kA (4s) | Main incoming feeder & transformer protection |
| Unit C | Load Break Switch Cell | 630 A | 20 kA (making) | Ring network loop connection & sectionalizing |
| Unit F | LBS + Fuse Combination Cell | 630 A / 125A (fuse) | 31.5 kA | Distribution transformer primary protection |
| Unit PT / M | Voltage Transformer & Metering | — | High Precision | Grid revenue metering & busbar voltage monitoring |
Prefabricated Box Substations & Solar Inverter Cabins
AIKEY designs and pre-assembles complete skid-mounted and containerized outdoor substations. Our line covers YZC renewable energy PV inverter cabins, containerized BESS battery energy storage substations, European compact substations (YB-12), and American combined pad-mounted substations (ZGS11-12) tailored for harsh desert and alpine climates.
YB-12 European Compact Substation
Three isolated compartments: High-Voltage Switchgear Room, Transformer Room, and Low-Voltage Distribution Room. Natural and forced cross-ventilation with thermal sensors.
ZGS11-12 American Combined Substation
Compact integration of transformer core, high-voltage load switch, and back-up current-limiting fuses immersed in the same tank. Ideal for solar farm string inverters and urban streets.
Industrial Power Reactors & Low Voltage Switchgear
AIKEY produces high-performance magnetic reactors and low-voltage distribution panels for power quality improvement. CKSG series filtering reactors suppress harmonic resonance and capacitor inrush currents. Inverter ACL (input) and OCL (output) reactors safeguard variable frequency drives and motor windings against catastrophic dv/dt voltage spikes.
Reactor Families & Technical Capabilities
| Reactor Family | Voltage Rating | Core Technology | Core Function & Protection Target |
|---|---|---|---|
| CKSG Series Reactor | 0.4 kV (3-Phase / 1-Phase) | Iron-core with air gaps | Suppresses 3rd, 5th, and 7th harmonics, prevents capacitor resonance. |
| ACL Inverter Input | 380V – 690V | Cold-rolled silicon steel | Reduces grid surge voltage, improves drive power factor, limits inrush current. |
| OCL Inverter Output | 380V – 690V | Low-loss magnetic core | Smooths inverter PWM wave, suppresses motor cable reflected wave & dv/dt. |
| CKSC / QKSC High Voltage | 6kV, 10kV, 35kV | Dry-type iron core cast | Limits short-circuit currents and dampens motor startup surge on HV grids. |
| MNS / GCS / GCK Panels | 0.4 kV (up to 4000A) | Modular draw-out design | Form 4b segregation, high breaking capacity, intelligent power distribution. |
