JINCHANG, China, July 25, 2025 /PRNewswire/ — When the characters “No fluctuation in telemetry data, zero abnormal alarm signals” appeared on the background monitoring screen of the Longkou Substation control room, the tense atmosphere at the scene finally relaxed. Recently, Jinchang Power Grid completed an unprecedented “live-line operation” on a 10 kV line, achieving the first “zero-power-outage” replacement of protection devices. This silent technological revolution has set a new benchmark for intelligent distribution network transformation.

Traditional protection device replacement is like a heart surgery, requiring a two-day power outage, which would halt production in enterprises and daily life of residents along the line. The breakthrough of Jinchang Power Grid this time lies in two core innovations: “full-process imperceptibility” and “full-protection parallel operation”. Zhao Jixian, the person in charge of the relevant work, defined it precisely: “This is a key leap from ‘power-outage transformation’ to ‘live-line operation’.”

To achieve this leap, the Secondary Maintenance Team (Substation Secondary Team) of the Substation Operation and Inspection Center of State Grid Jinchang Power Supply Company traveled to Qitai in Xinjiang and Ordos in Inner Mongolia to “learn from experience”. They drew on local experience in non-power-outage protection transformation and combined it with local actual working conditions to develop the “sand table rehearsal + platform transfer” plan. They rehearsed key actions such as device configuration and channel switching during short power outage maintenance intervals, and conducted three rounds of sand table drills for risks of protection refusal and misoperation—each simulation added a layer of security for actual operations.

The team surveyed and formulated the plan, locking details such as “devices placed 0.5 meters away from old cabinets” and “cables avoiding fire-fighting passages”. Facing the challenge of parallel compatibility between old and new devices, the team modified communication protocols and isolated control circuits to enable “seamless dialogue” between the two generations of equipment.

Before the transformation, a “1:1” operation simulation and 12 special briefings on risk points covered every link, and “measure one core and cover one core when removing wires” became an iron rule. Zhang Wenfei, deputy monitor of the Substation Operation Team (Substation Secondary Team) of Jinchang Power Supply Company, rechecked the wiring of the temporary protection platform one by one, and the “zero error” of 16 secondary circuits provided a “double insurance” for the operation.

Through this project, Jinchang Power Supply Company has also mastered cutting-edge skills such as “hot swapping” of protection devices and imperceptible channel switching, forming mature and promotable experience. As a key step towards a “high-reliability distribution network”, the Longkou Substation transformation technology will be promoted to old lines across the city, and is expected to reduce power outages by more than 500 hours annually.

HONG KONG, July 25, 2025 /PRNewswire/ — Cainiao’s Hong Kong Smart Freight Center has officially passed the Transported Asset Protection Association’s (TAPA) Facility Security Requirements (FSR) audit with an A-level rating—the association’s highest tier—making it one of the few smart freight center in the Asia–Pacific region to obtain this accolade. Located inside Cainiao’s Hong Kong eHub, it is also the first freight center in Hong Kong to achieve full RFID coverage across all operations.

TAPA is the world’s leading authority on warehouse and freight security, and its FSR program is considered one of the most stringent certifications in global logistics. The standard helps companies identify and manage security risks, particularly for high-value goods such as electronics, luxury items, and pharmaceuticals. FSR certification is divided into three levels—A, B, and C—of which A is the highest, covering more than 250 checkpoints spanning physical security, information security, and process controls.

Achieving FSR Level A demonstrates that the Hong Kong Smart Freight Center’s warehousing and transport security now meets top international benchmarks. Cainiao has put in place “bank-grade” protection through enhanced physical safeguards, data encryption and firewalls, and a multi-tier risk-assessment system.

This June, the hub completed end-to-end RFID deployment, boosting cargo-handling efficiency by 30% compared with traditional facilities. Alongside RFID, the center features AGVs, an automated air-cargo handling system (MHS), self-service check-in kiosks, and a “Ground Handling” WeChat mini-program—ensuring every cross-border parcel is trackable, visible, and traceable.

Situated in the South Cargo Precinct of Hong Kong International Airport, the Hong Kong eHub is only a five-minute drive from the runway. Its four-hour flight radius covers the Asia–Pacific’s core markets, enabling 72-hour delivery for time-sensitive goods. Real-time synchronization with Cainiao’s Liege eHub in Europe allows the full process—from arrival in Liege to release from an overseas warehouse—to be completed in as little as six hours, creating seamless global connectivity.

Cainiao’s cross-border parcel network now reaches more than 200 countries and regions, with 18 overseas sorting centers either built or underway, over three million square meters of cross-border warehouse space, and an annual handling capacity of more than 1.5 billion parcels—supporting upwards of 100,000 merchants and brands worldwide.

JINCHANG, China, July 25, 2025 /PRNewswire/ — On July 22nd, Jinchang region continued to experience high temperatures. The roaring harvesters in the farmland required stable electricity to operate, and the drying machines running overnight relied on continuous power supply. Agricultural machinery in the fields had become “big electricity consumers”. State Grid Jinchang Power Supply Company organized staff from Zhuwangbao Power Supply Station to go deep into the fields, carrying out line inspections and electricity safety publicity activities, building a solid electricity defense line for farmers’ safe summer harvest.

In combination with the characteristics of concentrated operation of agricultural machinery during the summer harvest, the company arranged professionals to conduct safety publicity to machine operators and farmers at field operation points and agricultural machinery concentration points. Beside a harvester that was being refueled, the staff pointed to the metal parts on the top of the machine and reminded the driver: “When working, you must pay attention to the 10-kilovolt line above and keep a safe distance of more than 3 meters to avoid wire contact and electric leakage.” During the publicity, the staff used easy-to-understand language and combined with typical cases to explain in detail the importance of keeping a safe distance between agricultural machinery and power supply lines during operation, as well as emergency treatment methods after accidental contact with wires. Through vivid explanations, the safety awareness of agricultural machinery operators and farmers has been effectively improved.

The company pays close attention to the usage dynamics of agricultural machinery in summer, optimizes the power guarantee plan for scenarios such as temporary power connection for cross-region operation of harvesters and concentrated power consumption of drying machines, further strengthens the on-duty and 值守 efforts, and increases the frequency of regular inspections, providing a solid electricity guarantee for the grain harvest in Jinchang region. It ensures the safe and stable power supply during wheat harvesting, effectively escorts agricultural production, and allows farmers to harvest with peace of mind and welcome the bumper harvest.
