5. Frequently Asked Questions (FAQ)
5.1 What is the difference between 10kV input and 15kV input working modes of this single phase pole mounted transformer?
This dual-input single-phase transformer reserves professional tapping adjustment structures for 10kV and 15kV input voltages. When matching a 10kV overhead grid, users can switch the internal tap position to adapt to 10kV rated input, ensuring accurate 220V voltage output under standard working conditions. When used in a 15kV voltage level grid, adjust the tap to the 15kV gear to avoid overvoltage operation of the equipment and ensure stable step-down effect. The overall structure and output parameters of the equipment remain unchanged under the two working modes, and only simple internal adjustment is required for switching, which is convenient for on-site grid matching construction. The dual-gear design makes the equipment compatible with more regional grid standards and avoids equipment waste caused by voltage level mismatch.
5.2 Is this 15kV/10kV to 220V oil immersed transformer suitable for long-term outdoor rainy and humid environments?
Yes, this pole-mounted single-phase transformer is specially optimized for outdoor harsh working conditions. It adopts a fully sealed integral welding oil tank and multi-layer sealing protection structure, which completely isolates the internal insulating oil and windings from the external humid air and rainwater. The external shell is treated with anti-corrosion and rust-proof spraying, and the high and low voltage bushings adopt outdoor special insulating materials with excellent moisture-proof and lightning-proof performance. It can operate stably in rainy, humid and coastal foggy environments for a long time, with no need for frequent manual protection. It is a highly adaptable outdoor distribution transformer for overhead line terminal power supply.
5.3 What kind of load scenarios are not suitable for this single-phase 220V output pole transformer?
This single phase pole mounted transformer is positioned for low-capacity scattered single-phase power supply, mainly serving civilian households and small light commercial loads. It is not applicable to three-phase industrial equipment, high-power mechanical loads and centralized high-capacity power consumption scenarios. Long-term overload operation and frequent impact load use will cause voltage instability and accelerated equipment aging. In addition, it is not recommended for indoor closed environments with high fire protection requirements and special chemical corrosive gas environments. For three-phase high-load industrial power distribution, users need to select matching three-phase power transformers to ensure safe and efficient system operation.
