What Are the Key Specifications of a 132kV 10000kVA Oil Immersed Transformer
2026-10-14
When specifying high-voltage power equipment for transmission and distribution networks, engineers must evaluate a wide range of electrical, thermal, and mechanical parameters. A 132kV 10000kVA Oil Immersed Transformer is a critical asset for substations operating at this voltage class, and Youbian has delivered hundreds of these units to utilities, industrial parks, and renewable energy projects worldwide. This article breaks down the essential specifications that determine performance, safety, and service life.
Core Electrical Specifications
The table below summarizes the primary electrical ratings that define a standard 132kV 10000kVA Oil Immersed Transformer. These values may be customized based on grid conditions and project requirements.
| Parameter | Typical Value |
|---|---|
| Rated Power | 10000 kVA |
| High Voltage Rating | 132 kV |
| Low Voltage Rating | 10.5 kV / 11 kV / 13.8 kV |
| Frequency | 50 Hz / 60 Hz |
| Phase | Three Phase |
| Vector Group | YNd11 / YNyn0 |
| Impedance Voltage | 10.5% ± 7.5% |
| No-Load Loss | ≤ 9.5 kW |
| Load Loss | ≤ 48 kW |
| Tap Changer | OLTC ± 8 × 1.25% |
These ratings ensure the 132kV 10000kVA Oil Immersed Transformer maintains voltage stability under both normal and emergency loading conditions.
Insulation and Cooling Design
Youbian manufactures each 132kV 10000kVA Oil Immersed Transformer with a high-grade mineral oil insulation system and copper windings. The cooling method is typically ONAN/ONAF, allowing the unit to operate at full capacity while keeping top-oil and winding temperature rise within IEC 60076 limits.
Key thermal specifications include:
-
Top-oil temperature rise: ≤ 55 K
-
Winding temperature rise: ≤ 65 K
-
Cooling stages: ONAN (natural) / ONAF (forced air)
-
Oil preservation: Conservator tank with rubber diaphragm
Mechanical and Protection Features
A 132kV 10000kVA Oil Immersed Transformer must withstand short-circuit forces and environmental stress. Youbian integrates the following protective components:
-
Buchholz relay for gas and oil-surge detection
-
Pressure relief valve
-
Silica gel breather
-
Winding temperature indicator with alarm and trip contacts
-
Oil level gauge and magnetic oil level sensor
The tank is fabricated from high-strength steel, pressure-tested to 0.5 bar, and finished with anti-corrosion coating suitable for C4/C5 environments.
Compliance and Testing Standards
Every 132kV 10000kVA Oil Immersed Transformer from Youbian is routine-tested according to IEC 60076 and IEEE C57.12.00. Type tests and special tests are available on request.
| Test Type | Standard |
|---|---|
| Routine Tests | IEC 60076-1 |
| Impulse Voltage Test | IEC 60076-3 |
| Temperature Rise Test | IEC 60076-2 |
| Short-Circuit Test | IEC 60076-5 |
| Dissolved Gas Analysis | IEC 60599 |
FAQ: Common Questions About the 132kV 10000kVA Oil Immersed Transformer
Q1: What is the typical lifespan of a 132kV 10000kVA Oil Immersed Transformer?
A: With proper maintenance, regular oil testing, and controlled loading, a 132kV 10000kVA Oil Immersed Transformer can operate reliably for 25 to 30 years. Youbian designs units with high-quality insulation and corrosion-resistant tanks to extend service life beyond 30 years in favorable conditions.
Q2: How often should oil testing be performed on a 132kV 10000kVA Oil Immersed Transformer?
A: Oil testing should be conducted annually for dissolved gas analysis and every two years for full oil quality checks. For a 132kV 10000kVA Oil Immersed Transformer operating under heavy load or in harsh environments, Youbian recommends semi-annual DGA testing to detect incipient faults early.
Q3: Can a 132kV 10000kVA Oil Immersed Transformer be installed outdoors?
A: Yes. A 132kV 10000kVA Oil Immersed Transformer is designed for outdoor installation when equipped with appropriate bushings, breathers, and weather-resistant coatings. Youbian provides IP54-rated control cabinets and corrosion protection for coastal or industrial environments.
