Product overview
R&D Innovation and Energy Efficiency Upgrading
The S13-Type Transformer is an independently developed product of Fengguang. Based on the original S11 Distribution Transformer , it integrates the research and application of new materials and new processes, and adopts a model combining independent innovation and technology introduction to carry out optimized and innovative design on the iron core and coil structures. It aims to reduce no-load loss and equipment operating noise, and promote the energy efficiency of distribution transformers to a new level.
Significant Noise Reduction and Leading Performance
This transformer performs excellently in noise control. Compared with the current national standard JB/T, its average noise level is reduced by 20%, which can create a quieter environment for equipment operation. At the same time, the product performance has reached the advanced domestic level, demonstrating strong technical advantages in the power distribution field.
Practical Appearance and Wide Adaptability
In terms of appearance, this transformer has a simple overall design, and the heat sinks are reasonably arranged, which can effectively ensure the heat dissipation performance of the equipment; various wiring components on the top are neatly arranged, facilitating installation and maintenance. With outstanding characteristics such as high energy efficiency and low noise, it can be widely used in various power distribution scenarios, providing strong support for the stable and efficient operation of the power system.
Design features
What the design is built around
Low-loss magnetic core
Cold-rolled grain-oriented silicon steel and a stepped core reduce no-load loss and audible noise.
Sealed tank construction
Welded tank, quality-gasketed cover and pressure-tested seals reduce oil leakage risk in outdoor duty.
Thermal margin for hot climates
Cooling surfaces and oil volume are selected for high ambient temperature and cyclic loading.
System compatibility
MV terminals, cable boxes and LV bushings are matched to the switchgear and protection scheme.
