Description
The S13-M.LR-10kV oil-immersed transformer is a low-loss, energy-efficient distribution transformer designed for medium-voltage power systems, especially in industrial, commercial, and infrastructure projects. As an upgraded version of the S11 series, the S13 model offers enhanced electrical performance, superior insulation, and lower no-load and load losses, contributing to energy savings and reduced operating costs.
This transformer is commonly used in 10kV power distribution networks, particularly where long-term reliability, reduced maintenance, and operational efficiency are critical.
Key Features of S13-M.LR-10kV Transformer
| Feature | Benefit in Industrial Applications |
| Ultra-Low No-Load Loss | Up to 30–40% lower than S11 series, improving energy efficiency |
| Rated Voltage: 10kV/0.4kV | Compatible with most medium-voltage grids |
| Oil-Immersed Cooling (ONAN) | Ensures long-lasting thermal stability and safe continuous operation |
| Hermetically Sealed Tank | Prevents air and moisture ingress, extends transformer lifespan |
| High-Quality Silicon Steel Core | Minimizes magnetic flux leakage and core loss |
| Fully Enclosed Structure | Ideal for harsh, outdoor, or dusty environments |
| Optional Aluminum or Copper Windings | Customizable based on budget or performance priorities |
lron core:
The three-dimensional triangle roll is intimately composed of three identical single frames. The three core posts are arranged in an equilateral triangle. The magnetic path length of the three core posts is completely the same, and the shortest. The loss of the three core posts is the same, S0 the three-phase magnetic circuit is balanced. The production efficiency is improved. The three-dimensional triangular wound core is the same as the planar wound core in that it is rolled on the production line to eliminate the quality fluctuations caused by manual lamination and stacking of the stacked iron core. At the same time, the body structure of the three-dimensional triangular wound iron core. transformer determines that its short circuit resistance is better than that of the planar transformer.
Oil tank:
The appearance is beautiful, the transformer oil tank adopts a near-micro triangle structure, So the volume is smaller than the conventional rectangular oil tank, the structure is compact, and the appearance is beautiful.
