SGB Series Environmentally Friendly Non-Encapsulated Dry-Type Transformer

As a professional power equipment manufacturer in China, Comewill's SGB Series Environmentally Friendly Non-Encapsulated Dry-Type Transformer employs an H-class insulation system, combined with Nomex® paper and solvent-free impregnating resin, achieving long-term temperature resistance up to 180℃ and meeting the UL94V-0 flame retardant standard. Its non-encapsulated open structure, combined with VPI vacuum pressure impregnation technology, ensures stable insulation and convenient maintenance.

The non encapsulated open structure combined with VPI technology ensures insulation stability and facilitates maintenance in the future. There are still many breakthroughs in performance: facing load fluctuations, it can operate under long-term 120% overload and short-term 150% overload; The operating noise is below 42dB, and it can be used in places that are sensitive to noise without any problem.

In addition, SGB Series Environmentally Friendly Non-Encapsulated Dry-Type Transformer also uses high permeability silicon steel sheets, and the electromagnetic design has been optimized, reducing power consumption by 10% -20% compared to ordinary models. The whole body is made of environmentally friendly materials, with almost zero VOC emissions, meeting green standards such as EU RoHS.

Features

Voltage level: 10~35/0.4kV
Capacity range: 30~3150kVA
Safety protection features: Adopting H-class insulation system, the core material is NOMEX ® Paper can withstand high temperatures of 180 ° C for a long time and also meets UL94V-0 flame retardant standards, eliminating fire hazards from the root. The non enclosed open structure combined with oil-free design completely eliminates the risk of explosion and can meet the safety requirements of densely populated and high-risk scenarios.

High efficiency and energy-saving features: using high magnetic conductivity silicon steel sheets, the electromagnetic circuit has been optimized and designed to reduce power consumption by 10% -20% compared to ordinary models, and both no-load and load losses have reached industry-leading levels. Equipped with 120% long-term and 150% short-term overload capacity, SGB Series Environmentally Friendly Non-Encapsulated Dry-Type Transformer can maintain efficient operation even with load fluctuations and reduce energy waste.

Low noise and quiet characteristics: By optimizing the core stacking technology and winding structure layout, the operating noise is controlled below 42dB (far below the industry average level). Designed to avoid mechanical vibration amplification and equipped with a silent heat dissipation structure, it can be directly used in noise sensitive environments such as data centers and medical facilities.

Environmental adaptation characteristics: Optimized cooling system that can operate stably in tropical environments with humidity exceeding 95%. The accessories are corrosion-resistant, coupled with a sealed design, making them more durable in harsh environments. The entire process uses environmentally friendly materials, with almost zero VOC emissions, in compliance with EU RoHS and other green standards, suitable for scenarios with strict environmental requirements.

Convenient maintenance feature: Non encapsulated open structure combined with VPI (vacuum pressure impregnation) technology, daily inspection and maintenance do not require complex disassembly. Modular design makes component replacement easier, reduces maintenance downtime, and lowers long-term operational costs and manpower investment.

Structural reliability characteristics: The high-voltage winding is a staggered laminated cake structure, while the low-voltage winding uses foil conductors. The current distribution is uniform, ensuring low leakage resistance and stronger short-circuit resistance. The precision balanced electromagnetic structure combined with high-strength fixed accessories can resist mechanical stress during transportation and operation, extending the service life of the equipment.

Application adaptation features: small size, flexible installation, suitable for various scenarios such as high-rise buildings, chemical parks, and urban power grid upgrades. SGB Series Environmentally Friendly Non-Encapsulated Dry-Type Transformer can meet the high-quality power supply needs of precision equipment and ensure the continuous operation of the power system under complex working conditions, with strong universality.
