Description
125 kVA 10 kV oil-immersed Power Transformer
In the 10 kV 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 125 kVA that can balance stability and durability when purchasing. The 125 kVA 10 kV 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 10 kV 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 125 kVA, 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.
Frequently Asked Questions Answered
Q1: Does this transformer match with Combined Photovoltaic Substations and Electric Power Converter?
A1: It is fully compatible. It can be directly connected to Combined Photovoltaic Substations to achieve the conversion of photovoltaic power supply, and when combined with Electric Power Converter, it can optimize the distribution of electrical energy. No additional interface modifications are required.
Q2: Can the heat dissipation effect be guaranteed during high-capacity operation?
A2: It can be fully guaranteed. The special insulating oil combined with an optimized heat dissipation structure ensures a higher efficiency than that of ordinary Dry Type Transformers. Even during long-term full-load operation, it can prevent overheating issues.
Q3: Is the after-sales response prompt when the equipment breaks down?
A3: The after-sales response is efficient. During the warranty period, free repairs and replacement of parts are available. In case of a breakdown, remote technical guidance can be provided. If the issue cannot be resolved remotely, a dedicated person will be assigned to handle it, without affecting the normal power distribution usage.
