The Usune three-phase oil immersed transformer is a static power device used for voltage and current conversion in AC power systems. Its core structure consists of the core and windings completely immersed in specialized transformer mineral oil. Stable operation is achieved through the dual properties of the insulating oil: heat dissipation is achieved through natural convection or forced circulation, removing heat generated during operation; simultaneously, reliable insulation is formed between the windings, core, and tank, preventing electrical faults.
This series of transformers covers mainstream voltage specifications of 10KV, 20KV, and 36KV, solving the pain points of traditional transformers such as high energy consumption, high noise, and weak short-circuit withstand capability. The overall structure is simple and durable, with strong environmental adaptability, allowing for long-term uninterrupted operation in various indoor and outdoor scenarios, providing efficient and stable transformer protection for power transmission and distribution systems.
A professional oil circulation cooling system ensures uniform temperature rise throughout the unit, eliminating localized overheating issues, allowing for long-term continuous operation at full load, and significantly reducing equipment failures caused by heat accumulation.
Utilizing high-purity mineral insulating oil combined with an optimized insulation structure, it provides comprehensive insulation protection for the windings and core, eliminating the risk of breakdown and ensuring long-term safe operation.
Relying on mature production processes and optimized structural design, the equipment boasts high operational stability, requiring minimal daily debugging and maintenance, resulting in extremely low operating costs.
The oil immersed transformer effectively handles instantaneous power fluctuations and peak load impacts from the power grid, adapting to diverse power supply scenarios such as industrial production and residential electricity consumption.
Compared to dry-type transformers, it has lower manufacturing costs; the fully sealed structure design simplifies daily maintenance, significantly reducing subsequent operating expenses and resulting in significant long-term economic benefits.
Employing high-quality raw materials and an anti-aging structural design, the equipment's stable service life can reach 20-30 years, far exceeding the industry average, effectively reducing equipment replacement costs.
Meets the needs of 35KV and 110KV high-voltage, high-capacity power applications, comprehensively covering various power transmission and distribution projects including residential, industrial, and substation applications.
The entire structure has been reinforced and optimized to withstand short-circuit surge currents under extreme grid conditions, preventing equipment damage from grid failures and improving grid operational safety.
For regional power voltage step-up/step-down and power distribution.
Providing stable industrial power supply for production lines and large machinery.
Ensuring a safe and stable supply of civilian power.
Used in various newly built, renovated, and expanded substation projects as core transformer equipment.
A1: Usune oil immersed transformers use mineral oil for heat dissipation and insulation, resulting in lower manufacturing and maintenance costs, better heat dissipation, and stronger overload capacity. They are more suitable for outdoor applications, large-capacity equipment, and long-term continuous load conditions. Dry-type transformers are mostly used in indoor high-fire-resistance environments, but they are more expensive and have weaker overload capacity. In conventional industrial, civil, and outdoor substation projects, oil immersed transformers offer better cost-effectiveness.
A2: Under standard installation and normal operating conditions, the equipment has a lifespan of 20-30 years. The product adopts a fully sealed structure, requiring minimal routine maintenance. Only periodic checks of the equipment's sealing, insulating oil level, and for leaks are needed. Frequent oil changes and parts replacements are unnecessary, significantly reducing later maintenance costs.
A3: Usune 10KV/20KV/36KV oil immersed transformers are highly adaptable to various environments, operating normally in typical indoor and outdoor settings. They support continuous full-load operation and can withstand instantaneous impact loads and short-circuit currents. Optimized for high and low temperature adaptation, the equipment can adapt to different seasons and regional operating environments, fully meeting the long-term stable power supply needs of power grids, industrial applications, and residential scenarios.
