Product overview

500kVA 10KV Oil-immersed Power Transformer

I. Core Information This product is a 500kVA 10KV oil-immersed power transformer, specially designed for large industrial scenarios, compatible with 10KV high-voltage power distribution systems. It is mainly used for large industrial parks, regional power distribution hubs, and large factories for high-power power supply. It can directly connect to existing power distribution lines without additional modifications, balancing stability and practicality, and addressing the high-power power supply needs of large-scale scenarios.

II. Core Features Heavy-load Adaptability: With a 500kVA large-capacity design, it can stably handle industrial-grade high loads. During operation, there is no heating or stalling, and it is suitable for complex industrial environments. Different from ordinary small-capacity transformers, it does not require frequent maintenance. Durable and Easy Maintenance: It adopts a sealed structure, preventing dust, moisture, and interference. It is suitable for outdoor and industrial harsh environments. Daily inspections only require observing the oil level and oil quality. No professional operation team is needed. The operation is simple. Compatible Adaptability: It can be directly used with Box Type Substation , High And Low Voltage Switchgear , and Electric Power Converter . No additional interface modifications are required.

III. Usage Precautions Installation requires choosing a flat and ventilated site. Avoid damp and high-temperature environments. Prevent the equipment from getting damp and short-circuited. Daily inspections only need to pay attention to the oil level and oil quality. No complex operations are required. If the oil color becomes turbid or has an odor, handle it promptly. Avoid severe collisions to the equipment to prevent damage to the sealing structure and affect the operational stability.

IV. Common Questions Q: Will this transformer have overheating or stalling problems when operating continuously for a long time? A: No, the dedicated cooling structure and efficient insulating oil ensure fast heat dissipation. Long-term continuous operation has no heating risks. It can provide uninterrupted power supply 24/7, meeting the high-power power supply requirements of industrial environments.

Q: If there is an abnormal oil level or oil quality change during operation, how should it be handled? A: No professional personnel are needed. Simply replenish qualified insulating oil and replace the deteriorated oil. No downtime for maintenance is required. Simple operation can restore normal operation.

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 500 kVA 10 kV Oil-Immersed power Transformer

What is 500 kVA 10 kV Oil-Immersed power Transformer best used for?
This model is specified at 500 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 500 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.
