Product overview
250KVA 20KV Low Loss Dry Type Transformer : The Preferred Energy-Saving Equipment for Industrial Power Distribution
In the current power distribution industry, high energy consumption and poor operational stability of traditional transformer equipment are common pain points. Many enterprises face challenges such as high equipment maintenance costs and insufficient adaptability to various operating conditions. To address these issues, this 250KVA 20KV Low Loss Dry Type Transformer utilizes a new casting process and energy-saving structural design to specifically optimize the core performance of the equipment. This equipment effectively reduces power distribution operating losses, improves power supply stability, and is suitable for various harsh industrial scenarios. Compared to traditional equipment, it significantly reduces energy consumption and failure frequency, enabling enterprises to achieve long-term energy savings and cost reduction. In a complete power distribution system, it can complement and adapt to different operating conditions with Oil-Immersed Transformers. It can also be used with Box Type Substations, High And Low Voltage Switchgear , and is compatible with Electric Power Converters, Combined Photovoltaic Substations , and other photovoltaic and electrical control equipment. It is widely used in various power supply scenarios such as factory power distribution, photovoltaic power plants, commercial buildings, and industrial parks, making it a core energy-saving transformer in high and low voltage power distribution systems.
Core Product Features
1. Ultra-Low Loss Energy-Saving Performance: The equipment uses low-loss core materials and optimized winding structure, effectively reducing no-load and load losses. Long-term operation can significantly reduce enterprise power consumption, meeting the industry demand for energy conservation and emission reduction, and is suitable for power distribution scenarios with long-term continuous operation.
2. Safe, Maintenance-Free, and Highly Adaptable: Compared to traditional oil-immersed equipment, Dry Type Transformers have no oil leakage or fire hazards, excellent insulation performance, and outstanding moisture-proof, dust-proof, and anti-aging capabilities. They require no frequent inspections or maintenance and are suitable for various installation environments, including indoor and outdoor enclosed spaces.
Installation & maintenance notes
- Compatible Installation: The equipment must be installed with a High and Low Voltage Switchgear of the corresponding specification. When networked with Combined Photovoltaic Substations or Electric Power Converters, voltage parameters must be calibrated in advance to ensure the stable and coordinated operation of the entire power distribution system.
- Routine Maintenance: No complex daily maintenance is required. Simply clean the surface dust regularly and check the tightness of the wiring terminals to effectively extend the equipment's lifespan and reduce the probability of failure.
- Frequently Asked Questions (FAQ)
- Q1: What are the differences in applicable scenarios between this 20KV dry-type transformer and the Oil Immersed Transformer ?
- A1: This product is safe and environmentally friendly, with no fuel hazard, making it more suitable for indoor, densely populated areas, and photovoltaic power stations. The Oil Immersed Transformer is more suitable for outdoor open spaces and large-capacity, long-distance power distribution scenarios. The two can be flexibly combined and used according to project conditions.
- Q2: Can the equipment be used in integrated power distribution scenarios with photovoltaic support?
