Skid Mounted Substation Transformer Product Description
Our 44 kV/46.2 kV Skid Mounted Substation Transformer is a high-performance, all-in-one power solution engineered to meet the rigorous demands of medium-voltage distribution networks, and this Transformer stands out for its modular design and robust construction that make it a top choice for diverse industrial and commercial applications. This Transformer integrates medium-voltage switchgear, core Transformer components, and low-voltage distribution panels into a compact skid-mounted unit, eliminating the need for complex on-site assembly and ensuring that the Transformer can be put into operation in the shortest possible time.
What makes this Transformer truly exceptional is its dual voltage compatibility, as the Transformer supports both 44 kV and 46.2 kV primary voltage inputs, which means the Transformer can seamlessly adapt to different grid specifications without additional modifications. The Transformer is built with weatherproof enclosures and corrosion-resistant stainless steel frames, so the Transformer can withstand extreme temperatures, high humidity, and coastal salt spray, ensuring that the Transformer maintains stable performance even in the harshest operating environments.
When it comes to cooling, the Transformer offers flexible options including OA (Air Natural), FA (Air Forced), and ONAN (Oil Natural Air Natural) cooling systems, allowing the Transformer to adjust its heat dissipation efficiency according to varying load conditions and ambient temperatures. This Transformer is highly customizable too—customers can tailor the Transformer’s capacity, voltage ratio, and accessory configurations to their exact project needs, and every Transformer complies with international standards such as IEEE, CSA, and IEC to guarantee the Transformer’s safety and reliability.

Skid Mounted Substation Transformer Product Advantages
A substation transformer is an integrated power equipment unit where the transformer, along with auxiliary components like switchgear, protection devices, and cooling systems, is pre-assembled and fixed on a sturdy steel skid base. Unlike conventional transformer that require on-site assembly and installation, it can be transported as a whole and put into use quickly after being hoisted in place, greatly reducing on-site construction time.
Q: What are the core advantages of substation transformer for temporary or mobile power supply scenarios?
A:Its core advantages include fast deployment, high mobility, and integrated design. It is especially suitable for temporary power needs such as construction sites, emergency repair of power grids, and outdoor events.
Q: Can substation transformer be customized according to specific project requirements?
A:Yes. Professional manufacturers can customize key parameters such as voltage level, rated capacity, cooling mode (ONAN/ONAF), and configuration of auxiliary devices (such as intelligent monitoring systems, reactive power compensation units) according to the user's power grid conditions, load characteristics, and installation environment to meet diverse application needs.
Q: What maintenance work is required for substation transformer during operation?
A:Daily maintenance includes regular inspection of the operation status of the transformer and its auxiliary devices; cleaning the surface of the equipment to avoid dust accumulation; checking the tightness of cable connections and the integrity of protective components; and conducting periodic electrical performance tests (such as insulation resistance measurement) to eliminate potential faults in advance.
Q: What is the highlight of the voltage compatibility of the Substation Transformer?
A: It features dual voltage compatibility, supporting both 44 kV and 46.2 kV primary voltage inputs. This allows the transformer to seamlessly adapt to different grid specifications without additional modifications.
Q: What operating environments can the Substation Transformer withstand?
A: Equipped with weatherproof enclosures and corrosion-resistant stainless steel frames, it can resist extreme temperatures, high humidity, and coastal salt spray, maintaining stable performance in harsh operating environments
Q: What cooling system options are available for this Substation transformer?
A: It offers three flexible cooling options: OA (Air Natural), FA (Air Forced), and ONAN (Oil Natural Air Natural), which can adjust heat dissipation efficiency according to load conditions and ambient temperatures.
