The SGOB 50kVA Oil Distribution Transformer utilizes an innovative sealed structure, replacing traditional oil storage devices with a nitrogen-shielded protective design to effectively isolate it from external environmental corrosion. This technology significantly reduces the oxidation rate of the internal medium by 80% and keeps annual moisture absorption to extremely low levels, significantly slowing the aging process and extending its overall service life to 30 years.
The insulation system utilizes a special oil-liquid combination of materials, achieving the highest level of protection in the industry. Its ability to withstand extreme voltage surges exceeds international standards by 20%, ensuring stable operation in harsh environments. This design, through optimized material ratios and structural layout, maintains excellent electrical performance and mechanical strength even under continuous high-intensity operation.
The SGOB 50kVA Oil Distribution Transformer excels in structural stability and operational reliability, meeting the stable power supply needs of industrial applications. The manufacturer strictly adheres to international technical specifications and employs a comprehensive quality control system to ensure the product has passed multiple safety certifications. This transformer is suitable for applications in energy, transportation, and construction, and is particularly suited to continuous operation under complex operating conditions.
Structural Features
The 50kVA Oil Distribution Transformer utilizes a reinforced insulation structure for enhanced shock resistance. Core components are constructed from high-permeability silicon steel sheets, and the conductors are wound with high-purity copper in multiple layers. Key connections are treated to prevent loosening. Its low-loss characteristics can reduce energy consumption by nearly 30%, meeting national standards for energy-saving technology promotion.
Material Processing
Refined surface treatment eliminates sharp structural angles, effectively controlling load losses. Low-loss silicon steel sheets are used as the magnetic material to reduce no-load energy consumption. Wooden insulation components resist deformation, and sealing materials eliminate leakage risks. All raw materials are verified under national quality standards, and supplier qualifications are subject to access control.
Company Qualifications
The company boasts a 40,000 square meter production facility and a professional R&D team, offering products covering over 30 categories of power equipment. With a comprehensive quality control process and numerous national patents, the company is equipped with advanced production lines such as automatic winding and vacuum impregnation, along with precision testing equipment, ensuring its products' high efficiency, energy saving, low noise, and stability.
HIGH QUALITY MATERIALS
A series of additional surface treatments are employed to ensure a smoother finish with no sharp edges, which contributes to reducing the transformer's load loss and enhancing its electrical performance.
As performance standards continue to rise, silicon steel sheets with lower unit losses are utilized to minimize the transformer's no-load losses.
High-quality laminated wood insulation is chosen for its durability, ensuring 50kVA Oil Distribution Transformer never cracks, even under the stress of short-circuit currents.
We have selected premium rubber sealing material to effectively prevent leakage and ensure tightness.
All raw materials have undergone rigorous quality inspections, and their manufacturers have been thoroughly examined in accordance with the national IS09000 standard.
