In the context of the global energy transition and the Middle East's vigorous promotion of power grid modernization, the demand for high-quality, environment-adaptive power equipment is surging. As a professional manufacturer of power transmission and distribution equipment, Hubian Electric has tailored the 35kV oil-immersed transformer with IP23 protection rating for the Middle Eastern market. This product integrates advanced technology, reliable performance and regional adaptability, providing a solid power guarantee for the region's industrial development, urban construction and renewable energy projects. With its excellent quality and compliant design, Hubian Electric's 35kV oil-immersed transformer is gradually becoming a trusted choice for power projects in the Middle East.
1. Product Overview: Core Advantages of 35kV Oil-immersed Transformer
Hubian Electric's 35kV oil-immersed transformer is a key equipment for medium-voltage power transmission and distribution systems, which is mainly composed of iron core, winding, on-load tap-changer, oil tank and cooling system. The product adheres to the design concept of high efficiency, energy saving and long service life, and has significant advantages in performance indicators and structural design, fully meeting the harsh operating conditions and high reliability requirements of the Middle East market.
In terms of core components, the transformer's iron core adopts high-quality grain-oriented cold-rolled silicon steel sheets, using a fully inclined non-porous binding structure. The multi-level stepped core with three or five joints effectively reduces magnetic resistance, resulting in low no-load loss and low noise. For large-capacity models, Hubian Electric also offers amorphous alloy iron core options, which can reduce no-load loss by an average of 72% and no-load current by 50% compared with traditional silicon steel sheets, significantly improving energy efficiency. The windings are made of high-purity oxygen-free copper conductors, including round copper wires with QQ polyacetal enamel insulation and flat copper wires drawn from oxygen-free copper rods. The windings are designed in cylindrical, continuous or new spiral forms according to different capacity requirements, ensuring sufficient electrical strength, mechanical strength and heat dissipation capacity. For models requiring higher short-circuit resistance, self-adhesive transposed conductors are adopted. After winding, the conductors are bonded to each other by heating, forming a rigid winding that can withstand greater bending stress, while reducing eddy current loss and circulating current loss, making the temperature distribution of the winding more uniform.
The oil tank of the transformer is made of high-quality steel plates through precision welding, with optional elliptical or rectangular structures. The heat dissipation components adopt finned radiators, expansion radiators or corrugated oil tanks, which can efficiently dissipate heat according to the operating load and ambient temperature. The oil tank undergoes strict sealing tests in the factory to ensure no oil leakage. The inner and outer surfaces are pickled, phosphated and coated with three primers and one topcoat, which has excellent corrosion resistance and can adapt to the high temperature, high humidity and sandstorm environment in the Middle East. In addition, the transformer is equipped with a complete temperature control system, which can monitor the winding temperature in real time. When the temperature exceeds the limit, it will automatically trigger an alarm or start the cooling device, ensuring the safe operation of the equipment.
2. IP23 Protection Rating: Customized Adaptation to Middle East Environment
The Middle East region is characterized by harsh climatic conditions, such as high temperature, strong sunlight, frequent sandstorms and occasional heavy rainfall. These environmental factors pose severe challenges to the operation stability of power equipment. Hubian Electric's 35kV oil-immersed transformer is specially designed with IP23 protection rating, which provides targeted protection for the equipment and ensures reliable operation in complex environments.
According to the international IEC standard, the IP23 protection rating consists of two digits, which respectively represent the protection level against solid objects and liquid ingress. The first digit "2" indicates that the transformer can prevent solid objects with a diameter greater than 12mm (such as small animals like rats, snakes, cats and birds) from entering the interior, avoiding short-circuit faults caused by these foreign objects and providing a safe barrier for live parts. The second digit "3" means that the equipment can prevent water droplets from entering within 60 degrees of the vertical line, which can effectively resist the impact of rainfall and dew condensation in the Middle East region, avoiding insulation damage caused by moisture intrusion.
It should be noted that while the IP23 protection shell provides effective protection, it will slightly affect the cooling capacity of the transformer. Hubian Electric has optimized the design of the heat dissipation system for this purpose. By increasing the area of the radiator, optimizing the air flow channel and using high-efficiency heat conduction materials, the impact of the protective shell on the cooling effect is minimized. The actual operation data shows that the capacity reduction of small and medium-capacity transformers is only about 5%, and that of large-capacity transformers is about 10%, which is far lower than the industry average and can fully meet the actual load requirements of the Middle East market. In addition, the protective shell of the transformer is made of high-strength corrosion-resistant steel, which is treated with anti-sand erosion and anti-ultraviolet coating, further enhancing the adaptability to the desert climate in the Middle East.
3. Compliance with Middle East Market Certification and Standards
The Middle East market has strict certification and standard requirements for imported power equipment. To ensure the smooth entry of products into the regional market, Hubian Electric's 35kV oil-immersed transformer has passed a number of international and local certifications, fully complying with the technical and safety standards of various countries in the Middle East.
First of all, the product meets the requirements of the International Electrotechnical Commission (IEC) standards, including IEC 60076 (Power Transformers) and other relevant standards, ensuring the international compatibility and technical advancement of the product. For specific markets in the Middle East, the transformer has obtained corresponding conformity certifications (COC) according to the requirements of different countries. For example, it has passed the SASO-COC certification required by Saudi Arabia, the TIR certification required by Kuwait, and the COC certification required by Iraq. The certification process strictly follows the local regulations, including document review, on-site inspection and certificate issuance. The test report, packing list and product parameters provided by Hubian Electric are completely consistent with the actual goods, ensuring the smooth progress of customs clearance.
For the United Arab Emirates market, the transformer has also passed the DEWA certification of the Dubai Electricity and Water Authority. The certification focuses on electrical safety, energy efficiency, electromagnetic compatibility (EMC) and environmental adaptability. The product has passed strict insulation withstand voltage test, temperature rise limit test and electromagnetic compatibility test, and meets the minimum energy efficiency standards (MEPS) of the UAE, which is in line with the local green energy policy requirements. In addition, all product labels and manuals are provided in Arabic and English bilingual versions, which complies with the local language requirements for imported products and facilitates the installation, operation and maintenance of customers.
