80 kVA 20 kV All-Copper Oil Immersed Transformer Outdoor Power Distribution System

The current Power Distribution Equipment market is flooded with imitation aluminum wire models, with excessive losses and insufficient withstand voltage becoming common pain points in the industry. Purchasers often encounter problems such as high-temperature leakage, long-term voltage deviation, and frequent downtime for maintenance, increasing operating costs. This 80 kVA 20 kV all-copper Oil-immersed Transformer uses high-purity copper windings combined with a sealed corrugated oil tank as its core solution, suitable for long-term continuous outdoor loads. Actual measurements show a significant reduction in no-load losses, reducing maintenance frequency by 60% over three years. This equipment can be used with box-type substations and High And Low Voltage Switchgear to build complete power distribution systems. Unlike indoor-specific dry-type transformers, it is more suitable for outdoor photovoltaic, mining, and construction site applications. It can be used with an Electric Power Converter to adjust the output current and can also be integrated into combined photovoltaic power substations for photovoltaic power boosting and transfer. The entire unit uses 100% pure copper windings, offering excellent conductivity and stable 20 kV high-voltage withstand capability. Heat dissipation is achieved through insulating oil circulation, resulting in superior overload capacity compared to similar dry-type units. It is primarily used in small and medium-sized factories, rural power grid upgrades, distributed photovoltaic power stations, and temporary field power supply projects. It continuously outputs stable three-phase voltage, ensuring uninterrupted operation of motors, lighting, and electrical control devices, balancing initial purchase cost-effectiveness with long-term energy savings.

Характеристики продукту

Low-loss pure copper winding structure: Entirely wound with oxygen-free copper wire, significantly reducing heat generation and energy loss compared to aluminum windings, suitable for long-term 20 kV high-voltage load operation.

Fully sealed corrugated oil tank protection: Isolates moisture and dust, reducing insulating oil oxidation and leakage, suitable for variable outdoor climates, and the enclosure is included as a complete set.

Поради

1.Ensure adequate ventilation and heat dissipation space during equipment installation. When using a high and low voltage switchgear, ensure proper grounding protection to prevent lightning strikes on the windings.

2.The insulating oil withstand voltage should be checked every six months. Timely filtration of deteriorated oil can effectively extend the service life of the entire unit.

FAQ (Часті запитання)

Q1: Can this Oil Immersed Transformer be used with Combined Photovoltaic Substations?

A1: Fully compatible. The voltage level and capacity of the equipment match the voltage boosting needs of small and medium-sized photovoltaic power plants. It can be used in conjunction with an Electric Power Converter to coordinate and regulate the output power of the photovoltaic system. Its stability for outdoor installation is superior to that of a Dry Type Transformer.

Q2: What basic operations are included in the daily maintenance of the equipment?

A2: Routine inspections check the oil level and the tank for leaks. Tighten the wiring terminals annually and perform regular insulation resistance tests. Frequent replacement of the insulating oil is not required; filtration is only necessary when the oil quality exceeds the standard.

Q3: What is the warranty period for the entire unit, and how is an oil leak handled?

A3: The core copper winding and oil tank are covered by a three-year warranty, and a complete set of test reports is included with the product. In case of leakage, contact technicians for remote guidance on replacing the sealing gasket. For overseas orders, parts can be shipped via mail.

Q4: Compared to Dry Type Transformers of the same capacity, why is this model the preferred choice for outdoor projects?
