Shanghai Second-hand Transformer Recycling Co., Ltd., committed to honesty in business, personal conduct, and work, has earned high praise from our clients. We continue to strive for excellence, establishing branches and offices in Qidong, Rugao, Tongzhou, Haimen, Hainan, and Gangzha, among other districts and counties. We are recognized as an advanced enterprise in Shanghai's 4050 Project and a burgeoning company dedicated to recycling.
Used Transformer Recycling: Dry-type transformers, voltage regulator transformers, oil-immersed transformers, magnetic transformers, no-load voltage regulator transformers, box-type transformers, power plant transformers, electrical equipment, cable and wire recycling and excavation, as well as mechanical and electrical equipment.
Business Scope: Corporate asset disposal and recovery, demolition projects, bidding and tendering (Jiangsu, Shandong, Anhui, Zhejiang, Fujian, Jiangxi, Henan, Shanghai, and the Yangtze River Delta region); second-hand equipment recovery, whole factory equipment recovery; recovery of second-hand power equipment, smelting equipment, generator sets, air conditioning units, industrial equipment, machinery and equipment, assembly lines/electrical equipment, telecommunications equipment; second-hand air conditioners, cables and wires; proficient in bidding and tendering for asset disposal and recovery, as well as comprehensive contracting for demolition projects for various large-scale enterprises and institutions.
One, classified by phase numbers:
(1) Single-phase Transformer: Used for single-phase loads and three-phase transformer banks.
(2) Three-phase Transformer: Used for voltage stepping up or stepping down in three-phase systems.
II. Categorized by Cooling Method:
Dry-Type Transformer: Cooled by air convection, commonly used for local lighting, electronic circuits, and other small capacity transformers.
(2) Oil-Immersed Transformers: Rely on oil as the cooling medium, such as oil-immersed self-cooled, oil-immersed air-cooled, oil-immersed water-cooled, and forced oil circulation, etc.
Part III: Categorized by Usage
(1) Power Transformer: Used for stepping up or stepping down voltage in power distribution systems.
(2) Instrument Transformers: Such as voltage transformers, current transformers, used for measuring instruments and relay protection devices.
(3) Test Transformer: Capable of producing high voltage for high-voltage testing of electrical equipment.
(4) Special Transformers: Such as electric furnace transformers, rectifier transformers, and voltage regulator transformers, etc.
Four: Categorized by winding configuration:
(1) Double-wound transformer: Used to connect two voltage levels within an electrical system.
(2) Three-winding Transformer: Generally used in regional substations of the power system to connect three voltage levels.
(3) Self-cooled transformer: Used to connect power systems with different voltages. Can also be used as a standard step-up or step-down transformer.
V. By core type:
Core-type transformer: A power transformer used for high voltage.
(2) Shell-type Transformers: Transformers used for high currents, such as electric furnace transformers and welding transformers; or power transformers for electronic instruments and TVs, radios, etc. We offer recycling services for scrapped, obsolete, or second-hand transformers.
Our company, with a spirit of continuous pursuit, dedicated to serving enterprises and society, adheres to the philosophy of "honesty, enthusiasm in service, and reputation above all." We welcome more corporate, institutional, and individual clients to discuss recycling opportunities for surplus old materials and obsolete equipment, either in person or by phone!
