Model Meaning
Product Discription
The S18/20/22 series of New Energy (wind/photovoltaic)  Chinese-style Transformer feature a three-phase, double-winding, oil-immersed, self-cooled, non-excitation voltage regulation, and fully sealed structure. Composed of the transformer body, oil tank, radiator, high and low voltage side insulation bushings, oil level gauge, pressure relief valve, temperature controller, oil conservator (usually required for capacities ≥630kVA), gas relay, moisture absorber, etc., it is a critical component of Chinese-style transformer. Together with high-voltage electrical components (such as high-voltage disconnectors and high-voltage fuses), low-voltage electrical components (such as low-voltage disconnectors, low-voltage current transformers, fuses, etc.), and the enclosure, they form the complete Chinese-style transformer. It offers a wide range of capacities and voltage levels up to 40.5kV. Meeting the latest national energy efficiency standards, these transformers boast strong overload capabilities, energy efficiency, and environmental protection. They are suitable for urban and rural buildings, residential communities, high-tech development zones, small and medium-sized factories, mines, wind power generation projects, and wind and photovoltaic projects with larger installed capacity per single box transformer.
Product Features
1	Compact structure: It adopts an integrated design that integrates transformers and low-voltage switchgear, occupying a small area and suitable for installation in spaces with limited room.
2	Safe and reliable: It employs mature insulating materials and advanced insulation technology, providing excellent insulation performance and high reliability, thereby ensuring the safe operation of the power system.
3	Energy-saving: It reduces losses during energy transmission and distribution, enhancing energy utilization efficiency and minimizing energy waste.
4	Convenient maintenance: The structural design takes into account the ease of maintenance and repair, allowing for convenient equipment inspection, maintenance, and replacement.
