10kV Distribution Transformers
125 kVA 10 kV Oil-Immersed power Transformer
In the 10KV medium-capacity power distribution scenarios, the equipment's load capacity is often insufficient and it is prone to failure during long-term operation. It is very difficult to find oil-immersed equipment with a capacity of 125kVA that can balance stability and durability when purchasing. The 125kVA 10KV oil-immersed power transformer can be directly paired with Box Type Substation for deployment, working in coordination with High And Low Voltage Switchgear . It can stably carry large-capacity loads and is less likely to experience overheating or failure. It is suitable for various complex power distribution environments and effectively solves the core problems in procurement and usage.

Product overview
125kVA 10KV oil-immersed Power Transformer
In the 10KV medium-capacity power distribution scenarios, the equipment's load capacity is often insufficient and it is prone to failure during long-term operation. It is very difficult to find oil-immersed equipment with a capacity of 125kVA that can balance stability and durability when purchasing. The 125kVA 10KV oil-immersed power transformer can be directly paired with Box Type Substation for deployment, working in coordination with High And Low Voltage Switchgear . It can stably carry large-capacity loads and is less likely to experience overheating or failure. It is suitable for various complex power distribution environments and effectively solves the core problems in procurement and usage.
This transformer is mainly used in 10KV medium-large capacity power distribution scenarios, covering medium-sized factories, large parks, photovoltaic support systems, etc. It can be used in conjunction with transformers of the same specification that are oil-immersed, and can also be connected to dry-type transformers to provide additional compatibility. It is combined with an Electric Power Converter to optimize the efficiency of power transmission, and is coordinated with Combined Photovoltaic Substations to achieve efficient utilization of clean energy. Its core value lies in basing on stable large-capacity output, taking into account durability and compatibility, reducing the frequency of equipment downtime, and lowering the post-purchase operation and maintenance costs as well as replacement costs for the buyer.
Product Features 1.It has a large capacity and strong adaptability. With a capacity of 125kVA, it can stably handle the power distribution load of medium-sized scenarios. Compared to ordinary Oil Immersed Transformers, it has a more outstanding load capacity and is less likely to fail due to overload.
2. Excellent durability. The oil-immersed sealing structure can effectively prevent dust and moisture, making it suitable for outdoor and complex industrial environments. When used in conjunction with Box Type Substation and High And Low Voltage Switchgear, the operational stability is further enhanced.
Tips for Use 1.During installation, it is necessary to ensure that the equipment is placed flatly and is properly connected to the High And Low Voltage Switchgear lines. Avoiding poor contact is crucial to prevent any impact on the load output. 2. Daily maintenance is not complicated. Regular checks on the insulation oil level and the sealing condition of the equipment are required to prevent oil leakage. Basic maintenance can be completed without the need for professional operation.
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.
