Product overview
315kVA 20KV Oil-immersed Transformer
Core Overview 315kVA 20KV oil-immersed Power Transformer , specially designed for 20KV high-voltage power distribution scenarios, suitable for capacity expansion of medium-sized industrial parks, town centralized distribution stations, large factories, and large-scale photovoltaic power supply. No complex renovations are required, directly connecting to the existing 20KV power distribution lines, installation is convenient, operation is stable, it can independently undertake large-capacity power supply in the area, and also adapt to the transition of old and new power distribution systems, solving the core pain points of large-capacity power supply in high-voltage scenarios, balancing durability and economy, without additional investment in renovation costs.
Product Features High-voltage tolerance performance is strong, precisely adapted to 20KV high-voltage environment, load output is balanced, long-term full-load operation does not heat up or trip, the ability to tolerate load fluctuations is outstanding, suitable for industrial regular and high-intensity power consumption scenarios. Adaptability is flexible, the structure is compact, the sealing protection is solid, it can be adapted to various scenarios such as indoor machine rooms, outdoor open distribution points, etc., can directly connect with Box Type Substation , High And Low Voltage Switchgear , seamlessly integrating, combined with Electric Power Converter to optimize power transmission, without additional interface modifications.
Use Tips Installation requires choosing a flat, ventilated, and dry site, avoiding low-lying, damp, and dusty areas, maintaining a reasonable safe distance from High And Low Voltage Switchgear, with standardized line connections, ordinary construction personnel can complete the installation.
Daily maintenance is simple, no need for dedicated personnel to monitor, regular checks on insulation oil level, oil color, and equipment shell sealing conditions, handle abnormalities in time, no need for professional technology, significantly reducing later maintenance costs.
Common Questions and Answers Q: Can the 315kVA capacity meet the full-scenario power supply requirements after the expansion of medium-sized industrial parks? A: Absolutely, the capacity precisely adapts to the power load of the park's expansion, can stably bear all scenarios of power supply, long-term continuous operation without pressure, no need to add additional equipment, effectively reducing the investment cost of expansion, and can also be combined with Combined Photovoltaic Substations to achieve photovoltaic grid 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.
