Product description
Amorphous alloy dry-type transformer is a new type of high-efficiency and energy-saving transformer with low no-load loss, stable insulation performance, and good economic and social benefits. It is widely used in airports, stations, urban power grids, high-rise buildings, and power plants.
Advantage
1. The transformer core is made of amorphous alloy strip, and the no-load loss is reduced by about 70% compared to S11 type transformers;
2. The transformer adopts copper foil coils for low voltage to enhance its ability to withstand short circuits;
3. The transformer connection group adopts Dyn11 to reduce the impact of harmonics on the power grid and improve power supply quality:
4. The transformer adopts vacuum oil injection, which can completely eliminate bubbles in the coil and ensure stable insulation performance;
5. This product is particularly suitable for areas with insufficient electricity, large load fluctuations, and difficult daily maintenance, and is suitable for rural, township, and urban residents’ daily electricity consumption.
1. Quality Management System ISO 9001: 2015
The operation of the entire Dongrun Electric system is strictly controlled and managed. This ensures the quality of the product at all stages, from receiving customer requirements to design, materials, production, installation, testing, packaging, delivery, and after-sales, all of which are operated under a strict and tight process.
2. Environmental Management ISO 14001: 2015
Dongrun Electric took the lead in applying the ISO 14001: 2015 environmental management system. The implementation of this process demonstrates Dongrun’s responsibility to a wide range of customers. Dongrun is committed to providing the most environmentally friendly high-quality technical products.
3. Certification Certificate ISO / IEC 17025: 2017
The ISO / IEC 17025: 2017 certification confirms that Dongrun’s technical quality meets the requirements of all specific international testing and calibration laboratory standards. All Dongrun products are fully tested in qualified laboratories before leaving the factory to ensure stable quality and provide customers with absolute peace of mind.
