Power Distribution Substation

Qingdao BEST Steel Structure Co., Ltd. is one of the leading manufacturers and suppliers of power distribution substation in China. With abundant experience, Our factory offer high quality products made in China with competitive price. Welcome to contact us for customized service and OEM service.

Power Distribution substations are the core of terminal power supply in the power system. They mainly convert medium-voltage electric energy of 10kV/35kV into low-voltage electric energy of 380V/220V, and directly supply power to end users such as residential areas, commercial districts, industrial and mining enterprises. They have four core functions: voltage transformation, load distribution, protection and control, and electric energy metering.The product structure is as follows:The high-voltage compartment is equipped with ring main units or load switchgear, fuses, surge arresters and live-line indicators, realizing the connection, protection and switching of 10kV/35kV power supply.The transformer compartment is mainly equipped with oil-immersed transformers or dry-type transformers with a capacity of 30kVA~2500kVA, completing the transformation from medium voltage to low voltage.The low-voltage compartment is equipped with low-voltage main cabinets, outgoing cabinets, reactive power compensation devices and metering meters, which are responsible for low-voltage distribution, overload or short-circuit protection, and power factor adjustment.The cabinet enclosure is made of stainless steel or composite materials, which is dustproof, waterproof, anti-corrosion and heat-insulated, adapting to harsh outdoor environments.

The mainstream products are mainly box-type substations, indoor distribution stations and compact ring-network distribution stations, showing an overall technical trend of miniaturization, integration, intelligence and maintenance-free operation.

High Efficiency and Energy Saving with Extremely Low Loss: Adopting S11/S13 series oil-immersed transformers and SCB10/SCB14 series dry-type transformers, both no-load loss and load loss meet the national first-class energy efficiency standard. Long-term operation can greatly reduce power loss, comply with the requirements of green and energy-saving development, and lower the user's electricity cost.

Compact Structure and Space Saving: The overall integrated design is adopted, especially for box-type substations, which integrate the three major units of high voltage, voltage transformation and low voltage into one. Compared with traditional civil engineering substations, the floor area is reduced by more than 70%, and no complex civil engineering is required.

Safe and Reliable with Comprehensive Protection: It has complete protection functions, which can realize multiple protections such as overcurrent, quick break, overload, temperature, lightning protection and ground fault, effectively avoiding equipment damage and power supply accidents. The protection level of outdoor products reaches IP54 and above, and the shell is made of waterproof, dustproof, anti-corrosion and heat-insulating materials, which can adapt to harsh outdoor environments such as high temperature, severe cold, humidity and heavy dust.

Easy Installation and Time Saving: Factory prefabricated integrated production, all components are pre-assembled and debugged. On site, only foundation fixing and cable connection are needed, and installation and power-on can be completed in 1-3 days, which greatly shortens the construction period. Compared with traditional civil engineering substations, the construction period is shortened by more than 60%, which is especially suitable for temporary power supply and emergency power supply scenarios.

Flexible Adaptability and Strong Customization: It can customize rated capacity, voltage level, cabin layout, shell color, etc. according to user needs, covering various types such as box-type, indoor and compact ring network. It can not only meet the conventional power supply needs of residential areas and commercial districts, but also adapt to the special power supply needs of industrial enterprises, new energy, municipal infrastructure, etc., and is movable and reusable.

Distribution substations are the core equipment for terminal power supply in the power system. They mainly convert medium-voltage electric energy of 10kV/35kV into low-voltage electric energy of 380V/220V, providing stable and safe electric energy supply for end users such as residential areas, commercial districts, industrial and mining enterprises.

Establish a full-process quality control mechanism from raw material procurement to product delivery to ensure that each product meets the standards;

Strictly control raw materials, select qualified suppliers, conduct strict inspections on core raw materials such as transformers, switchgear and components, and prevent unqualified materials from entering the warehouse; set up key process inspection points during the production process, conduct full-process supervision on links such as frame welding, box forming, component assembly, and wiring commissioning to ensure that the process meets the standards; for factory inspection, each product must complete all inspections including withstand voltage test, insulation test, interlock test, appearance inspection and function commissioning before leaving the factory, and a test report shall be issued before the product can leave the factory; establish a complete after-sales system, provide services such as installation guidance, commissioning, maintenance and inspection, conduct regular quality return visits, and timely solve problems encountered by users during use.
