In the 220 kV high-voltage medium-low capacity power distribution scenarios, the high equipment energy consumption and insufficient adaptability flexibility are industry pain points. It is a challenge for you to find equipment that can simultaneously meet the requirements of high-voltage adaptation, load matching, and cost control during procurement. We have launched the 3150 kVA/220 kV high-voltage Power Transformer, which precisely adapts to high-voltage medium-low load scenarios. You can choose between Oil Immersed Transformer or Dry Type Transformer specifications as needed, and it is seamlessly compatible with Box Type Substation, High And Low Voltage Switchgear. It can be used for the grid connection of small and medium-sized Combined Photovoltaic Substations, regional high and low voltage branch power distribution, and dedicated power supply for key units. When paired with Electric Power Converter, it can optimize the accuracy of power transmission and effectively solve the problems of unstable high-voltage medium-low load power supply, high energy consumption, and cumbersome adaptability. It achieves efficient and low-consumption operation, helping purchasers precisely control investment costs and meet the diverse needs of high-voltage medium-low load power distribution. Its core value lies in high-voltage adaptation, precise load matching, and cost control. Its applications cover high-voltage branch distribution networks, small and medium-sized new energy bases, large supermarkets and key municipal units’ high-voltage power supply. It is the core preferred equipment for 220 kV level medium-low capacity power distribution scenarios.

Product Features:

Precise load matching, energy-saving and efficient: Rated voltage 220 kV, capacity 3150 kVA. It precisely meets the high and low load requirements of high-voltage systems, avoiding energy waste caused by capacity redundancy. The insulation performance meets standards and can be stably connected to the 220 kV high-voltage power grid. When paired with the Electric Power Converter, it can further reduce transmission losses and is suitable for small and medium-sized Combined Photovoltaic Substations for grid connection, with outstanding power supply efficiency.

2. Flexible adaptation and controllable cost: You can choose the Oil Immersed Transformer or Dry Type Transformer specifications based on the installation scenario. There is no need to modify the existing Box Type Substation, High and Low Voltage Switchgear supporting system. The installation is convenient, the operation and maintenance process is simplified, and no professional operation and maintenance team is required. This significantly reduces the overall cost of equipment procurement, installation, and later operation and maintenance.

Tips :

The installation must strictly follow the 220 kV high-voltage equipment installation specifications. Special attention should be paid to insulation protection and lightning protection grounding. For Oil Immersed Transformers, regular inspections of oil quality, oil level, and sealing conditions are required. For Dry Type Transformers, the installation environment should be kept dry and dust-free. When operating in conjunction with High And Low Voltage Switchgear and Electric Power Converter, regular checks of the line interfaces are necessary to prevent overload and poor contact.

FAQ (Frequently Asked Questions):

Q1: Can this transformer be used for small and medium-sized Combined Photovoltaic Substations, and what is the grid connection effect like?

A1: Fully compatible with small and medium-sized Combined Photovoltaic Substations. The 3150 kVA capacity precisely meets the power generation and grid connection requirements of small and medium-sized new energy bases. It can be directly connected to the 220 kV high-voltage grid. When paired with an Electric Power Converter, it can enhance grid connection stability and power utilization efficiency. It seamlessly integrates with Box Type Substation and High And Low Voltage Switchgear, and no additional equipment modification is required.

Q2: Are there significant differences in the long-term operation and maintenance costs between the two types of transformers?

A2: The operational costs vary slightly and are generally low. For Oil Immersed Transformers, the insulating oil needs to be replaced once a year. Daily maintenance only requires checking the oil level and quality. For Dry Type Transformers, the insulating oil does not need to be replaced. Only regular dust cleaning and maintaining a dry environment are required. Both specifications do not require a professional operation team. Ordinary operation personnel can operate them after simple training.

Q3: What is the product warranty policy? Can timely after-sales support be provided in remote areas?

A3: Offer a 2-year free warranty. During the warranty period, non-human faults can be repaired or replaced for free for core components. The after-sales team is available 24/7 for response. Whether in remote areas or urban areas, they can arrive at the scene to handle the faults within 48 hours. At the same time, they provide lifelong technical guidance to completely address the after-sales and usage concerns of the purchasers.
