Product overview

400kVA 10KV Oil-immersed Transformer

I. Core Content 400kVA 10KV Oil-immersed Transformer, mainly for large-capacity heavy-load power supply, suitable for large industrial parks, centralized power distribution hubs and other scenarios. It can be networked with the same specification Oil-immersed Transformer (oil-immersed transformer) and combined with Electric Power Converter (electric power converter) to optimize power transmission and meet the centralized power supply requirements of large-scale scenarios, while balancing stability and economy.

II. Product Features Strong overload capacity: The 400kVA capacity can stably meet the high-load requirements of large industrial scenarios. It has outstanding overload capacity. Compared to ordinary oil-immersed equipment, it runs more stably and is less likely to experience downtime. Excellent sealing protection: Adopting a high-strength sealing structure, it is dustproof, moisture-proof, and corrosion-resistant, suitable for outdoor and complex industrial environments. No frequent maintenance is required, and the long-term usage cost is reduced.

III. Common Questions Q: Can this transformer meet the continuous power supply requirements of large factories?

A: Absolutely, the 400kVA capacity can stably meet the centralized power supply of large factories. There is no pressure for long-term full-load operation, and there is no concern about overload issues.

Q: Is it necessary to renovate the existing Power Distribution Equipment for connection?

Design features

What the design is built around

Low-loss magnetic core

Cold-rolled grain-oriented silicon steel and a stepped core reduce no-load loss and audible noise.

Sealed tank construction

Welded tank, quality-gasketed cover and pressure-tested seals reduce oil leakage risk in outdoor duty.

Thermal margin for hot climates

Cooling surfaces and oil volume are selected for high ambient temperature and cyclic loading.

System compatibility

MV terminals, cable boxes and LV bushings are matched to the switchgear and protection scheme.

Buyer questions

FAQ for 400 kVA 10 kV Oil-Immersed power Transformer

What is 400 kVA 10 kV Oil-Immersed power Transformer best used for?
This model is specified at 400 kVA and 10 kV. It is used where the site load, fault level and environmental conditions match the approved datasheet. Share the load profile, ambient temperature, altitude and grid code and the design can be checked against the application.
What is the typical lead time for 400 kVA 10 kV Oil-Immersed power Transformer?
Standard distribution units typically ship in 25-40 days after drawing approval. Large power transformers and integrated stations are scheduled by design review, core and winding production, tanking, testing and packing. The exact date is confirmed in the quotation.
Which standards and tests are supplied?
The transformer family is designed to GB 1094.1, GB/T 6451 and IEC 60076. Routine tests include winding resistance, ratio, impedance, no-load loss, load loss, insulation resistance and power-frequency withstand. Type and special tests are available on request.
Can the transformer be customised for 60 Hz or a hot climate?
Yes. Frequency, ambient temperature, altitude, enclosure, corrosion class and terminal arrangement are project inputs. The design is adjusted before production, and the approved datasheet becomes the inspection basis.
How do I choose between copper and aluminium windings?
Copper gives higher short-circuit strength and a more compact winding; aluminium can reduce first cost for lightly loaded units. The choice depends on fault level, load profile, loss evaluation and the buyer's specification. Both are available.
