Key Features – 80 kVA Oil-Immersed Distribution Transformer
The 80 kVA oil-immersed distribution transformer sits at the heart of low-voltage rural distribution networks, agricultural power supply projects, small commercial facilities, and light industrial installations. At this capacity, the transformer is the primary interface between the 10 kV distribution grid and the 400 V systems that power end-use equipment — making reliability and efficiency over a service life measured in decades, not years, the defining criteria for specification.
Zhongxin General’s 80 kVA units are available across three GB 1094 energy efficiency grades (Grade 1, Grade 2, and Grade 3) and meet EU Commission Regulation No. 548/2014 Tier 1 and Tier 2 requirements — making them suitable for both domestic Chinese projects and international export markets in Europe, Southeast Asia, the Middle East, and Africa where IEC 60076 compliance is required. The 50 Hz / 60 Hz dual-frequency availability further broadens the unit’s applicability to Americas markets and other 60 Hz grid systems.
Transport and packaging. At 80 kVA, the transformer ships as a fully assembled unit with oil filled, requiring no on-site field assembly beyond cable termination and earthing. Standard road transport is straightforward; units can also be prepared for sea freight with nitrogen-sealed tanks and export-grade wooden crating on request — a practical consideration for international buyers evaluating Chinese suppliers.
Available options and configurations include: off-circuit tap changer (standard, ±2×2.5%), on-load tap changer (OLTC) for applications requiring voltage regulation under load, nitrogen-sealed tank for long-distance sea transport, oil temperature indicator, winding temperature indicator, and silicone oil filling for high-fire-safety environments. Low voltage can be customised to 380V, 400V, 415V, 433V, or other values to match local grid standards.
Applicable Standards & Testing
Every 80 kVA transformer manufactured by Zhongxin General undergoes a full programme of routine tests before leaving the factory. No unit is dispatched without a complete test report.
Routine tests (every unit):
- Winding resistance measurement
- Voltage ratio and vector group verification
- No-load loss and no-load current
- Load loss and short-circuit impedance
- Induced overvoltage withstand test
- Separate-source AC withstand test
Type tests (conducted on representative units; reports available on request):
- Temperature rise test
- Lightning impulse test
Special tests (available on request):
- Partial discharge measurement
- Sound level (noise) measurement
- Short-circuit withstand test
All tests are conducted in accordance with IEC 60076 and GB 1094. Test reports are issued as standard documentation and can be provided to customers prior to or alongside shipment.

About Zhongxin General — Oil-Immersed Transformer Manufacturer & Factory
Zhongxin General (Sichuan Zhongxin General Electric Energy Co., Ltd.) is a China-based manufacturer and factory specializing in oil-immersed and dry-type power transformers, HV/MV/LV switchgear, prefabricated substations, energy storage systems, and EV charging infrastructure. Headquartered in Xinjin District, Chengdu, Sichuan Province, the company holds National “Little Giant” Enterprise status — China’s highest SME innovation designation — alongside National High-Tech Enterprise certification.
Our transformer portfolio covers 30 kVA to 100 MVA, configurable to a wide range of voltage classes including 6 kV, 10 kV, 11 kV, 15 kV, 22 kV, 33 kV, 35 kV, 66 kV, 110 kV, and 132 kV, in both GB and IEC / ANSI standard configurations for domestic and international projects. The 80 kVA oil-immersed distribution transformer described on this page is one of the most widely deployed units in our portfolio — supplied to rural distribution networks, agricultural power projects, commercial facilities, and industrial installations across China and international markets.
Every transformer we manufacture undergoes full routine testing to IEC 60076 or GB 1094 before dispatch. Test reports are issued as standard documentation with every order.
Real Projects & Real Deliveries
The best way to evaluate a transformer supplier is to see what they have actually built and delivered — not just what they list on a specification sheet.
Zhongxin General publishes detailed case studies for completed projects, covering the full lifecycle from factory manufacturing and factory acceptance testing through to on-site installation and commissioned operation. Recent deliveries include a 31,500 kVA OLTC transformer for a new dedicated 35kV substation in Xinjiang, a 63 MVA / 110kV OLTC unit for a strategic LNG and helium production facility in Ningxia, a modular smart substation for an LNG energy project in Shaanxi, and transformer exports to Nepal, Kazakhstan, and European markets.
If you are evaluating Zhongxin General as a supplier for your project — whether for a single distribution transformer or a complete substation package — our case study library gives you the documented evidence to make that assessment with confidence.
