This particular unit is built to GB 20052-2024 Tier 3 energy efficiency. We also manufacture the same model to Tier 1 (the highest efficiency grade under GB 20052-2024), which exceeds the requirements of Commission Regulation (EU) No 548/2014 and Commission Regulation (EU) 2019/1783 of 1 October 2019 — so the same core platform can be specified for projects that require EU-compliant efficiency documentation.
How Our 8000 kVA Dry-Type Transformers Are Made
Every core starts with cold-rolled grain-oriented silicon steel, cut to size and precision-stacked by hand at our Chengdu factory to keep no-load losses and noise within spec.
The clamped core is then fitted into the pre-cast high- and low-voltage windings — this is also the stage where we switch between copper and aluminum conductor depending on the order. As a factory, we produce both: copper winding for maximum efficiency and compact size, and aluminum winding as a lower-cost alternative for budget-sensitive projects that can accept a larger footprint for the same rating.
Product Highlights
- H-class insulation, 125K temperature rise — reliable operation in demanding indoor environments
- AN/AF cooling — the built-in forced-air fans allow a load boost above the AN rating during peak demand
- Yd11 vector group, 35kV/10.5kV — sized for direct connection to industrial 35kV distribution systems
- Copper or aluminum winding — flexible to match project budget and space constraints
- GB 20052-2024 Tier 3 as standard, Tier 1 available — efficiency grade matched to the destination market’s requirements
Typical Applications
The SCB11-8000/35 is commonly specified for industrial plants, mining and metallurgy loads, and large public-facility power systems where dry-type is preferred over oil-immersed for fire-safety reasons — a similar approach to the intelligent power distribution system we delivered for a 129,900 sqm hospital campus.
Global Delivery
8000 kVA dry-type transformers from Zhongxin General have shipped to industrial and infrastructure projects both domestically and overseas.
Applicable Standards & Testing
Every 8000 kVA dry-type transformer manufactured by Zhongxin General undergoes a full routine test programme before dispatch. No unit is dispatched without a complete test report.
Routine tests (every unit): winding resistance measurement; voltage ratio and vector group verification (Yd11); no-load loss and no-load current; load loss and short-circuit impedance; induced overvoltage withstand test; separate-source AC withstand test; partial discharge measurement.
Type tests (reports available on request): temperature rise test (verifying the 125 K rise under H-class insulation); lightning impulse test (to the LI170AC70/LI75AC35 insulation level).
Special tests (available on request): sound level (noise) measurement; short-circuit withstand test.
All tests are conducted to IEC 60076-11, GB1094.1,2-2013, GB1094.3-2017 and GB/T 10228-2023. Factory Acceptance Test (FAT) with client witness is supported. Test reports and ITP documentation are provided as standard with every order.
Available Options & Configurations
- Winding material: copper (standard, as tested — see nameplate above) or aluminium
- Voltage class: this unit ships as 35 kV/10.5 kV; other primary/secondary combinations (6 kV, 10 kV) available on request, configurable to match local grid standards
- Secondary output: 10.5 kV as tested; lower-voltage secondary options (400 V, 415 V, 433 V) available for distribution-level projects
- Frequency: 50 Hz (standard, as tested) or 60 Hz
- Energy efficiency grade: GB 20052-2024 Grade 3 as standard (this unit); Grade 1 available on request, exceeding EU Regulation No 548/2014 and its 2019/1783 amendment
- Tap changer: ±2×2.5% off-circuit (standard — matches the 5-position tap range shown above); OLTC available on request
- Protection degree: IP00 as tested (open/ventilated); IP20/IP30 with metalwork enclosure available
- Temperature control: intelligent controller standard, coordinating the AN/AF cooling fans; RS485/Modbus optional
- High-altitude versions for installations above 1000 m a.s.l.
- Tropical, high-humidity, and coastal salt-spray versions available
Typical Applications
The 8000 kVA cast resin dry-type transformer is specified wherever large power demand, indoor fire safety, and long-term maintenance-free operation must be achieved simultaneously:
- Large industrial facilities — heavy manufacturing, chemical plants, metallurgical operations
- Data centres — high-density power supply with zero oil-spill risk
- New energy projects — large-scale solar PV step-up and wind farm collection substations
- Petrochemical & LNG — fire safety critical environments, offshore and onshore
- Rail transit — traction substations and station power distribution infrastructure
- Major commercial development — airports, large mixed-use complexes, hospitals
For examples of Zhongxin General delivering power infrastructure at this scale, see our 16,730 kVA intelligent power system for Xinjin District People’s Hospital, which included 12 dry-type transformers across multiple capacity ratings, and our 22 KYN28-12 switchgear units and 2 SCB18 transformers shipped for a CATL supply chain project in Zigong.
