The S13/S20/S22 series fully sealed oil-immersed transformers are suitable for power systems with an AC frequency of 50Hz and a rated working voltage of 20kV and below. They are used as distribution transformers in industries such as petroleum, metallurgy, chemical, textile, light industry, and in places with significant dust.
This series of products features an advanced design with significant improvements and enhancements in materials, structure, and craftsmanship. The high and low pressure clamps use steel tension bands or upper and side beams to create a sturdy frame structure, enhancing the core clamping force and the ability to withstand transportation impacts. It has strong short-circuit resistance, an aesthetically pleasing appearance, reliable operation, low losses, and low noise, reaching the advanced level of similar foreign products.
10kV level SC(B)10/SC(B)11/SC(B)12/SC(B)13/SC(B)14 type epoxy resin cast dry-type transformers can serve as an upgrade to oil-immersed distribution transformers. They are the best-performing products among various dry-type transformers, particularly suitable for important locations such as urban power grids, high-rise buildings, business centers, theaters, hospitals, hotels, tunnels, subways, stations, docks, airports, underground power stations, laboratories, and combined substations.
Transformers can convert the voltage from the power grid into the voltage required by the system or load, enabling the transmission and distribution of electrical energy. This transformer can replace traditional transformers with silicon steel cores and is widely used in outdoor distribution systems. The extensive operation of this product in the network can achieve significant energy-saving effects and reduce atmospheric pollution. This product is particularly suitable for areas with insufficient power supply, large load fluctuations, and difficulties in daily maintenance. Due to its fully sealed structure, the insulating oil and insulating medium are protected from atmospheric pollution, allowing it to operate in humid environments, making it an ideal distribution device for extensive distribution networks in both urban and rural areas.
YB □ -12/0.4(F·R) Outdoor Prefabricated Substation (European Style) is widely used in urban power grid renovation, residential communities, high-rise buildings, industrial and mining enterprises, hotels, shopping malls, airports, railways, oil fields, docks, highways, and temporary power supply facilities in both indoor and outdoor locations.
This product is developed by incorporating the latest advanced technology from abroad while considering domestic practical conditions. The entire product features a compact size, easy installation and maintenance, low noise, low loss, anti-theft, strong overload capacity, and full protection. It is suitable for new residential areas, green belts, parks, stations, hotels, construction sites, airports, and other locations.
The box transformer is divided into three parts: the high-voltage chamber, the low-voltage chamber, and the transformer itself, arranged in a "目" shape. Except for the transformer heat sink and the body that protrude outside the box, all other live compartments are sealed within independent chambers. Each chamber is isolated into independent compartments with partitions, and there is a lower manhole in the box for easy installation and maintenance.
KYN28A-12 type indoor AC metal-clad medium voltage switchgear. It is suitable for three-phase AC rated voltage of 12kV and rated frequency of 50Hz power systems, used for receiving and distributing electrical energy, as well as controlling, protecting, and monitoring the circuit.
SRM6-12 gas-insulated metal-enclosed switchgear is a three-phase AC 50Hz, fully insulated and fully sealed metal-enclosed switchgear using SF6 gas.
The XGN15A-12(SF6) type unit-type AC metal-enclosed ring network switchgear (hereinafter referred to as ring network cabinet) is a new generation of high-voltage electrical products that we have designed and developed independently by introducing advanced foreign technology and in accordance with the requirements of domestic agricultural electricity and urban network transformation. All technical performance indicators meet the IEC62271-200:2003 and GB3906 standards.
The GGD type AC low-voltage distribution cabinet is suitable for power users such as power plants, substations, and industrial enterprises. It is designed for AC systems with a frequency of 50Hz, a rated working voltage of 380V, and a rated working current of up to 3150A, serving for the conversion, distribution, and control of electrical energy for power, lighting, and distribution equipment.
