Product overview
30kVA 20KV Oil-immersed Power Transformer
I. Core Overview 30kVA 20KV oil-immersed power transformer, mainly targeting small-capacity high-voltage distribution adaptation. The core is used for small-scale industrial scenarios, small parks, outdoor distribution points, and small-power power supply for photovoltaic systems. It is compatible with 20KV high-voltage distribution systems, requiring no complex renovations, and can be directly integrated into existing distribution lines to meet the precise adaptation requirements for small-capacity high-voltage distribution, balancing stability and convenience.
II. Core Features Small-capacity precise adaptation: The 30kVA capacity meets the power supply needs of small-scale scenarios, avoiding power waste from large-capacity equipment. Compared to ordinary Oil Immersed Transformers, it is smaller in size, more flexible in deployment, and suitable for outdoor small distribution points.
High-voltage stable operation: Compatible with 20KV high-voltage environments, during operation there is no voltage fluctuation. The sealed oil-immersed structure is dust-proof and moisture-proof, suitable for outdoor humid and dusty environments, requiring no frequent maintenance, and reducing long-term operation costs. Flexible compatibility: It can be directly connected to Box Type Substation (box-type transformer), High And Low Voltage Switchgear (high and low voltage switchgear), and can be combined with Electric Power Converter (electric power converter) to optimize power transmission. It can also be combined with Combined Photovoltaic Substations (photovoltaic substations) to achieve small-power photovoltaic power supply conversion.
III. Installation Tips Installation does not require occupying too much space. Choose a flat and ventilated outdoor or indoor location, maintain a reasonable distance from High And Low Voltage Switchgear, and avoid poor line contact. Daily maintenance is simple. Regularly observe the insulation oil level, clear and undistorted oil color indicates normal operation, no need for professional personnel to be on duty, and ordinary people can complete basic checks.
IV. Common Questions Q: Can the 30kVA capacity meet the daily power supply needs of small parks and outdoor distribution points? A: Absolutely, the 30kVA capacity precisely adapts to small parks, outdoor distribution points, and small-power photovoltaic support, meeting daily power supply needs without power waste, with stable operation and no pressure.
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.
