Product Usage
This product has the advantages of low no-load loss, oil-free, flame-retardant and self-extinguishing, moisture-resistant, crack-resistant and maintenance-free. Any place where ordinary dry transformers are currently used can be replaced by amorphous dry transformers, which can be used in high-rise buildings, commercial centers, subways, airports, stations, industrial and mining enterprises and power plants. It is especially suitable for installation and use in places with high fire protection requirements such as flammable and explosive.
Three-phase dry three-dimensional wound core distribution transformer
DKSC series grounding transformer
Grounding transformers are often used to provide an artificial loadable neutral point for system grounding at ungrounded points in the system. The neutral point of this product is connected to an arc suppression coil or resistor, and then grounded. It can be equipped with a secondary winding of continuous rated capacity as the power supply for the station (station).
Single-phase pole-mounted oil-immersed power transformer
Overview
Western developed countries, Southeast Asia, and South America use a large number of single-phase transformers as distribution transformers. In distribution networks with decentralized power supply, single-phase transformers have great advantages as distribution transformers. It can reduce the length of low-voltage distribution lines, reduce line losses, and improve power supply quality. It adopts a high-efficiency and energy-saving rolled iron core structure design. The transformer is characterized by column-mounted suspension installation, small size, low infrastructure investment, and low voltage reduction. The power supply radius can reduce low-voltage line losses by more than 60%. The transformer adopts a fully sealed structure, with strong overload capacity, high continuous operation reliability, simple maintenance and long service life.
It is suitable for rural power grids, remote areas, scattered villages, agricultural production, lighting and power consumption. It can also be used for railways and urban power grids for energy-saving transformation of pole-mounted distribution lines.
