Description

400 kVA 20 kV Oil-immersed Transformer

Core Overview
400 kVA 20 kV oil-immersed Power Transformer, featuring 20 kV high-voltage large-capacity power supply, suitable for medium-sized industrial parks, large factories, and town centralized distribution substations for capacity expansion and large-power power supply for photovoltaic projects. No complex renovations are required, directly connecting to the existing 20 kV distribution lines, installation is convenient, operation is stable, capable of independently undertaking large-capacity high-voltage power supply in the area, and also seamlessly connecting with the existing distribution system, suitable for the transition between new and old power grids, solving the core pain points of insufficient high-capacity power supply and unstable operation in high-voltage scenarios, balancing durability and economy, reducing subsequent investment.

Product Features
High-voltage large-capacity adaptation, precisely matching the 20 kV high-voltage environment, with a 400 kVA capacity that can stably meet the high-load demands of all scenarios, load output is balanced, long-term full-load operation does not generate heat or trip, has strong tolerance to load fluctuations, suitable for industrial high-intensity and uninterrupted power usage scenarios.

Flexible compatibility, adequate protection, compact structure, solid sealing process, can be adapted to various complex environments such as indoor computer rooms and outdoor open distribution points, can directly connect with Box Type Substation, High And Low Voltage Switchgear, seamlessly integrate with Electric Power Converter to optimize power transmission, no additional interface modifications required, wider adaptability.

Use Tips
Installation requires choosing a flat, ventilated, and dry site, avoiding low-lying, damp, dusty, and high-temperature areas, maintaining a reasonable safe distance from High And Low Voltage Switchgear, with standardized line connections, ordinary construction personnel can complete it, no need for professional teams.

Daily maintenance does not require dedicated personnel on duty, regular checks on insulation oil level, oil color, and equipment shell sealing condition, if oil color is turbid, oil level is insufficient, or sealing is loose, handle it promptly, no professional skills required, significantly reducing operation and maintenance costs.

Common Questions and Answers
Q: Can a 400 kVA capacity meet the high-voltage power supply requirements for uninterrupted production in large factories and parks?
A: Absolutely, the 400 kVA large capacity can stably meet the high-load power supply for all scenarios, supports 24-hour uninterrupted operation, will not have power supply interruptions or voltage instability issues, suitable for industrial uninterrupted production needs, and can be combined with Combined Photovoltaic Substations to achieve photovoltaic grid connection.

Q: For grid renovation projects, can the equipment directly connect to the original 20 kV distribution lines without large-scale renovations?
A: Yes, the interface specifications are fully universal, can directly integrate into the existing 20 kV high-voltage renovation lines, no need to modify the original distribution layout, the renovation implementation efficiency is high, can be put into use quickly, significantly reducing the time and cost of grid renovation.

Q: For long-term outdoor use, is the weather resistance and service life of the equipment guaranteed?
Answer: There is a guarantee. It is made of industrial-grade weather-resistant materials and has an enhanced sealing structure, which can effectively resist wind, sun exposure, rain, and dust erosion. It can withstand the complex outdoor environment and has a much longer service life than ordinary Oil Immersed Transformers. Under normal use, it does not need frequent replacement, thereby reducing the replacement cost.
