High/Low Voltage Prefabricated Substation Recycling

Recycling of High/Low Voltage Prefabricated Substations. Shanghai high and low voltage prefabricated substations, also known as box-type substations, abbreviated as box transformers, are compact power distribution equipment that integrates high-voltage switchgear, distribution transformers, and low-voltage power distribution devices according to a specific wiring scheme.

Shanghai prefabricated substations can directly supply high voltage to load centers, resulting in low line losses and high power supply quality, i.e., "high-voltage power reception—transformer step-down—low-voltage distribution." Due to high requirements for power supply reliability, prefabricated substations with high-voltage ring network or dual power supply and automatic low-voltage network switching have become the preferred choice for power distribution equipment.

Large-scale recycling of box-type substations, prefabricated substations, outdoor box-type substations, combined box-type substations, high and low voltage prefabricated substations. Mobile substation recycling.
Classification of Prefabricated Substations

1. By overall structure. Conventionally divided into European-style and American-style substations. The former, previously known in China as combined substations, arrange high-voltage switchgear, distribution transformers, and low-voltage power distribution equipment in three closely adjacent compartments, connected electrically via cables or busbars. The latter, previously called prefabricated substations, place the transformer body, high-voltage load switches, fuses, and high and low voltage connections within a common sealed oil tank.

2. By installation location: indoor and outdoor.

3. By high-voltage wiring method: terminal wiring, dual power supply wiring, and ring network wiring types.

4. By enclosure structure: integrated, split, and other types.

Features of Prefabricated Substations

1. High degree of automation. Intelligent design, protection system uses microcomputer-based comprehensive automation devices, installed in a decentralized manner, featuring remote measurement, remote signaling, remote control, and remote adjustment, i.e., "four remotes."

2. Factory prefabrication. Designed according to the main wiring diagram and external equipment, determining the models and specifications of main equipment components, installed and debugged in the成套厂, ready for direct on-site use. High-voltage lines can directly supply power to load centers.

3. Advanced, safe, and reliable. Advanced enclosure manufacturing process, shell made of aluminum-zinc coated steel plate, resistant to rust, internal cladding with aluminum alloy扣板, sandwich layer with fireproof insulation material, air conditioning and dehumidification devices installed inside the enclosure, internal equipment operation不受外界影响,适应-40~+40℃.

4. Flexible combination methods. Compact structure, each box constitutes an independent system, with flexible and varied combinations.

5. Low cost. Reduces costs by 40%~50% compared to conventional substations of the same scale,占地面积仅为同规模变电所的1/10, aesthetically pleasing appearance,协调与环境.Shanghai, Nanjing, Wuxi, Xuzhou, Changzhou, Suzhou, Nantong, Lianyungang, Huai'an, Yancheng, Yangzhou, Zhenjiang, Taizhou, Suqian, Jiangyin, Yixing, Xinyi, Pizhou, Liyang, Jintan, Changshu, Zhangjiagang, Kunshan, Taicang, Qidong, Rugao, Haimen, Dongtai, Dafeng, Jiangdu, Yizheng, Gaoyou, Danyang, Yangzhong, Jurong, Xinghua, Jingjiang, Taixing, Jiangyan
