SenDian Power Transformer: Lighting the Light of Innovation in the Power World

In modern society, electricity is like blood, supporting the operation of various industries. From the dazzling lights of bustling cities, to the roaring machines in factory workshops, to the precision instruments in research laboratories, a stable and reliable power supply is crucial. Behind this, transformers play an irreplaceable role as the core equipment for power transmission and distribution. Today, we will delve into a company that has demonstrated outstanding performance in the field of power transformers - Henan Sendian Power Equipment Co., Ltd.

Deeply cultivating the industry for more than ten years, forging strong strength

Since its establishment in 2009, SenDian Power has been deeply involved in the manufacturing of 35KV and below power transformers, dry-type transformers, box type transformers, special transformers, and complete sets of high and low voltage control equipment for more than ten years. The company is located in Dazhaoying Industrial Agglomeration Zone, Xinxiang City, Henan Province, with a registered capital of 50 million yuan. It has its own factory area covering 26640 square meters, including a standardized production workshop of 12800 square meters.

Entering the production workshop of SenDian Electric Power, highly automated production equipment and sophisticated production lines operate in an orderly manner, creating a busy scene. At present, the company has more than 100 employees, including 22 engineering technicians with college degree or above. These professionals gather in various key positions, providing a solid guarantee for the progressiveness of product technology, stability of quality and efficiency of production. With years of profound accumulation in technology research and development, as well as production and manufacturing, SenDian Electric Power has become an undeniable force in the industry.

Innovation leads development, patents witness strength

In the fiercely competitive power equipment market, innovation is the driving force for enterprise development. Sendian Electric Power is well aware of this and continues to increase research and development investment, actively exploring new technologies and processes. In 2024, the company achieved remarkable results in technological innovation, obtaining multiple patent breakthroughs consecutively.

In June 2024, Sendian Electric Power successfully applied for a patent for a "three-dimensional winding iron core transformer winding machine" (authorization announcement number CN222734807U). Traditional winding machines often require tedious disassembly and replacement of screws when facing winding rings of different sizes, greatly affecting production efficiency. The new winding machine from SenDian Electric Power cleverly solves this problem by innovatively designing output components, rotating components, and clamping components. It can flexibly adapt to different winding rings without complex disassembly, significantly improving production flexibility and efficiency, and laying the foundation for the efficient production of three-dimensional winding iron core transformers.

In December of the same year, Sendian Electric Power applied for a patent for "a dry-type transformer production positioning fixture". With the increasing demand for renewable energy, the demand for dry-type transformers in the market is growing, but traditional production processes are inefficient. This fixture from SenDian Power is equipped with a multifunctional design including an automatic cleaning system, efficient drilling device, and cooling measures. During work, the cleaning board under the fixture can automatically move forward and backward to clean up residual iron filings on the table, maintain a clean working environment, and reduce safety hazards; The drilling system is connected to the drive motor through stainless steel flexible pipes to achieve precise and efficient drilling; During the drilling process, the cooling component synchronously discharges coolant to prevent equipment overheating and ensure equipment safety and durability. These innovative designs have effectively improved the production and processing efficiency of dry-type transformers, meeting the urgent market demand for efficient production.

At the beginning of 2025, SenDian Power once again reported good news, with two patents authorized: "A dry-type transformer with protective function" and "A protective structure for energy-efficient transformers". A dry-type transformer with protective function is equipped with a lightning rod at the top of the box, which is connected to the coil inside the conductive box on the side of the box through a conductive wire. This can effectively solve the problem of dry-type transformers being easily damaged by lightning strikes in thunderstorm weather; The protective structure for energy-efficient transformers is designed with a water collection box, sliding rod, spring, and protective shell. The protective shell automatically lowers to cover the transformer in rainy weather and resets automatically in sunny weather, protecting the transformer from rainwater erosion without affecting normal heat dissipation. These patented technologies have comprehensively improved the performance and protection level of transformers, demonstrating the innovative strength of SenDian Power.

Strict standards create excellent quality

Product quality is the lifeline of an enterprise, and SenDian Electric Power always puts quality control in the first place. The company strictly adheres to international standards in production, fully implements ISO9000:2000 quality system standards and ISO14000:2004 environmental system standards, and undergoes strict testing at every stage from raw material procurement to product delivery.

In terms of raw materials, SenDian Power insists on independent production of main materials and strictly controls the quality source. The accessories are selected from international mainstream brands to ensure that the product has advantages such as low loss, low noise, long life, and easy installation. For example, the amorphous alloy iron core distribution transformer produced by it uses high-quality amorphous alloy materials, which are composed of elements such as iron, nickel, cobalt, boron, carbon, etc. It is a isotropic soft magnetic material with characteristics such as low magnetization power, high resistivity, and high hardness. Compared with traditional silicon steel sheets, amorphous alloys have a thinner thickness (only 0.027mm) and a lower filling coefficient (0.75-0.8), but their electrical resistivity is 3-6 times that of silicon steel sheets, which significantly reduces the no-load loss of transformers. Based on the GB/T6451 standard group I value, it decreases by 70%, effectively improving energy utilization efficiency.

During the production process, advanced automation equipment and exquisite craftsmanship are closely coordinated to ensure that every transformer meets high-quality standards. Before leaving the factory, each product must undergo multiple strict tests, including electrical performance testing, insulation testing, voltage withstand testing, etc. Only products that pass all tests can be labeled with the SenDian Power logo and enter the market. With this persistent pursuit of quality, the service life of Sendian Power products can reach 30 years, far exceeding the industry average, providing users with long-term stable and reliable power guarantee.
