10 kV Weitu B691 Line Renovation Project in Ningbo Hangzhou Bay New Area

The 10-kV Weitu B691 line, fed by the 110-kV Bailu Substation, primarily supplies power to the eastern reclamation area of the New District, covering a reclaimed land area of 67 square kilometers. Currently, the line is overhead, with the main feeder using LGJ-150 conductors and most branch circuits employing LGJ-120 or smaller conductors, resulting in relatively small cross-sectional areas. In 2015, the maximum load factor reached 63%. It is anticipated that the installed capacity for new infrastructure projects in the reclamation area between Piers 11 and 12 will reach 9,000 kVA, a demand that the existing line can no longer accommodate. To meet the growing regional load and enhance line interconnection, the renovation project for the 10-kV Weitu B691 line in the Ningbo Hangzhou Bay New Area takes into account the current overhead configuration of the 110-kV Bailu Substation–10-kV Weitu B691 line, its operational status, load registration data, and route alignment. The project involves undergrounding the main section of the Weitu B691 line from Pole No. 1 to Pole No. 20-20, constructing six new ring-main units along the route, and laying 3.4 kilometers of cable, thereby improving both the region’s power supply capacity and reliability. In addition, this project was selected as a representative initiative of the Ningbo Power Supply Company of State Grid Corporation of China for the Zhejiang Provincial Electric Power Company’s Quality Project Evaluation, ultimately ranking among the top 20 high-quality distribution network construction and renovation projects of State Grid Zhejiang Electric Power Co., Ltd. for 2017.

Technical Services Project for the Line Section of the 35 kV Power Supply Project (Phase I) in the Ningbo Petrochemical Zone

This project is located in the Zhenhai Petrochemical Zone, bounded by Wanghai South Road to the east, Haitian Middle Road to the west, Lanshan Road to the south, and Tongtu Road to the north. The project comprises two 220-kV Dian’gen Substation and two 220-kV Yanhai Substation, each of which supplies two 35-kV circuits to the Xiepu 35-kV Switchyard. <br/> (1) Route from the 220 kV Dian’gen Substation to the Xiepu 35 kV Switchyard: A double-circuit cable from the 220 kV Dian’gen Substation runs to Cable Terminal Tower No. 1; after the cable is brought up, an overhead line extends to the tower on the east side of Zhenpu Road, turns left and runs parallel to Lanshan Reservoir toward the north, then connects to Cable Terminal Tower No. 17, where the cable is brought down. The route continues along the north-side roadbed of Wanghai South Road to Xingye Road and Fengxiang Road, ultimately reaching the Xiepu 35 kV Switchyard. <br/> (2) Route from the 220 kV Coastal Substation to the Xiepu 35 kV Switchyard: The double-circuit cable outgoing from the 220 kV Coastal Substation turns left at the intersection of Yuejintang Road and Haifeng Road, then turns right at the intersection of Haitian Middle Road and Haifeng Road, and finally runs along the west-side roadbed of Haitian Middle Road to the Xiepu 35 kV Switchyard.

220kV Xianxiang Substation–Ningbo Boway 35kV Power Pipeline Project

Ningbo Boway New Materials Co., Ltd. is a wholly owned subsidiary of Ningbo Boway Alloy Materials Co., Ltd. and was established in 2018. The company’s products are primarily used in high-end markets such as the smart internet, smart terminal devices, new-energy vehicles, and semiconductors, meeting the needs of Fortune Global 500 companies and industry-leading benchmark enterprises. <br/> This project is the 35 kV Boxin Substation transmission and transformation works constructed to support Ningbo Bowei New Materials Co., Ltd.’s annual production project for 50,000 tonnes of special alloy strip. The main transformer capacity is 2 × 16,000 kVA, with a single-circuit power supply. A new 35 kV transmission line is built to connect to the 35 kV bay at the 220 kV Xianxiang Substation. The new line employs a combined cable-and-overhead installation method, with a total length of approximately 10.96 kilometers. The entire substation adopts an all-indoor design, with protection and monitoring equipment arranged in a hierarchical, distributed configuration and a comprehensive automated control scheme.

35kV Substation Project of Ningbo Rongbai New Energy Technology Co., Ltd.

Ningbo Rongbai New Energy Technology Co., Ltd. is a high-tech new-energy-materials enterprise controlled by Beijing Rongbai Investment Holding Co., Ltd., and operates as a multinational group specializing in the R&D and commercialization of cathode materials for lithium-ion batteries. To support the company’s development, it has undertaken the “Annual Expansion and Upgrade Project for a 33,000-ton-per-year Production Line of Ternary Cathode Materials for Power Lithium-Ion Batteries,” which includes the construction of a 35-kV substation with two main transformers, each rated at 10 MVA, one 35-kV incoming feeder, and seven 10-kV outgoing feeders. The substation is a three-story above-ground structure, with a total project investment of approximately RMB 22 million. Our company provides end-to-end technical services for this project, including the feasibility study report on the grid connection system, preliminary design, and detailed civil and electrical construction drawings.

Ningbo Oriental Cable Co., Ltd. 35kV Dedicated Transformer Connection System

Ningbo Oriental Cable Co., Ltd. has constructed a new 35-kV substation to support the implementation of the “Demonstration Project for the Application of High-End Marine Energy Equipment Systems.” The grid connection scheme for this project is as follows: a new 35-kV transmission line will be built to connect to the 220-kV Houdun Substation; two main transformers, each with a capacity of 12.5 MVA, will be installed; one 35-kV incoming feeder and eleven 10-kV outgoing feeders will be provided. The substation adopts an all-indoor layout and is configured as a single-story above-ground structure. During the design phase, multiple optimization iterations were conducted in consultation with the client to achieve a compact and rational electrical layout, thereby minimizing the footprint and reducing capital investment.
