Welcome to Dehuang - Leading Power Transformers Supplier for Africa, Middle East, and Southeast Asia. Guangdong Dehuang Electric Power Equipment Co., Ltd. (formerly Shantou Transformer Factory) is a private technology enterprise and a designated manufacturer of power transformers in the national machinery industry. The company has a registered capital of 15 million yuan. In 1985, the company introduced advanced power transformer production equipment from Switzerland, Norway, France, and other countries, including silicon steel sheet cross-cutting lines, foil winding machines, low-frequency vacuum drying, and corrugated tank production lines. The company's products are sold nationwide and are well-received by customers.

The S11-M and S13-M series oil-immersed transformers are a new generation of energy-saving, low-noise, and environmentally friendly transformers. They feature reinforced corrugated tanks and a fully sealed structure. The transformer body adopts a new structure. For capacities above 800kVA, a gas protection device can be installed to enhance reliability and safety. These transformers are characterized by no need for core lifting, low maintenance, low loss, low noise, and strong short-circuit resistance, reaching the contemporary advanced level in China.

The SC(B)11-30~3150/10 series three-phase resin-insulated dry-type transformers are new products developed by our company to meet the needs of national urban and rural power grid upgrades, improve product performance, and enhance production efficiency. This series of products complies with national standards GB6450 and GB/T10228. Based on the SC(B)10 series dry-type transformers, the no-load loss and load loss have been optimized and reduced, and the electromagnetic design and structural design have been optimized. They are widely used in power plants, substations, industrial and mining enterprises, user substations, and other 10kV power and distribution systems.

The prefabricated substation (European-style box transformer) is a complete substation pre-assembled in the factory, including transformers, high voltage compartments and control equipment, low voltage compartments and control equipment, internal wiring, metering, reactive power compensation, lightning arresters, and other auxiliary equipment, all housed in a common enclosure or a set of enclosures. It is a new equipment for urban and rural substation upgrades and is widely used in urban street lighting, green areas, high-rise buildings, commercial centers, residential areas, villages, factories, and railways. It is extensively used in urban power grid construction and is a new type of distribution device that replaces building distribution rooms and pole-mounted transformers. Before installation, the box transformer should be placed in a suitable location according to normal usage conditions.

The combined transformer (American-style box transformer) is a fully insulated, fully sealed, oil-immersed, self-cooled, and waterproof three-phase distribution combined transformer designed for pad-mounted installation. It is suitable for three-phase distribution systems with a rated voltage of 10kV and meets the requirements of relevant national standards.

The American-style box transformer is divided into two parts. The front part includes high and low voltage operation compartments. The high voltage operation compartment includes high voltage input and output terminals, load switches, no-load high voltage tap changers, plug-in fuses, pressure relief valves, thermometers, oil level gauges, and oil drain valves. The low voltage operation compartment is equipped similarly to domestic products or can be configured according to user requirements. The rear part of the box contains an oil-immersed transformer and a backup current-limiting fuse, using transformer oil or high-fire-point insulating liquid as the insulating medium. The entire box transformer is fully enclosed, featuring waterproofing, safety, and convenient operation.
