I. Project Overview
Project Name: CCCC Expressway UPS Procurement Project (2025) Applied Product: Bodiantong BOD Series Indu-grade Power Frequency UPS Power Supply Project Background: As the core carrier of the regional transportation hub, CCCC Expressway bears the responsibility of ensuring the stable operation of highway t, monitoring systems, communication systems, and emergency command equipment. The continuity and stability of power supply directly affect road traffic safety and operational efficiency. In 2025, to the highway power supply guarantee system and replace aging equipment, CCCC Expressway launched the UPS procurement project. There is an urgent need for industrial-grade power frequency UPS power supplies that are table to the complex scenarios of expressways and possess high reliability, to ensure the uninterrupted 7x24-hour operation of various core equipment.

II. Core Customer
 Requirements
(1) Ensure 24/7 uninterrupted power supply for core equipment such as highway toll collection, monitoring, and communicaion systems. Eliminate equipment shutdowns and data loss caused by utility power outages and voltage fluctuations, thereby safeguarding road traffic safety and operational continuity.

(2) Select industrial-interactive UPS systems that feature robust construction and strong immunity to interference. These systems must be suitable for complex grid environments in highway outdoor equipment rooms and toll stations, effectively resisting grid anlies such as voltage sags and flickers to provide clean and stable power output.

(3) Facilitate convenient operation and maintenance with support for intelligent monitoring. This allows for real-timonitoring of equipment status and timely fault warnings, catering to the dispersed working characteristics of highway maintenance personnel while reducing daily maintenance costs and workload.

(4) Ensure reliable product quality and rapidles response. The equipment should possess strong environmental adaptability and a long service life, aligning with green and energy-saving concepts to reduce long-term operational energy

III. Solution
Combining the operational requirements of China Communications Construction Expressway and industry power supply standards, we have customized a d procurement solution for them, selecting the Bodetong BOD series industrial-grade power frequency UPS. This solution comprehensively meets the multi-scenario power supply needs of expresswaysating a safe, stable, and efficient power protection system:

(1) Precise Model Selection: Through professional load calculation, we selected BOD series power frequency UPS models with matching poatings. Utilizing a 50Hz industrial frequency transformer, the output 380V three-phase voltage complies with industrial power standards. This allows direct connection to various coray equipment such as toll collection and monitoring systems, while reserving expansion space to meet future business growth needs.

(2) Core Performance Assurance: Adopting double-conversion online te it achieves zero-millisecond seamless switching between utility power and backup power, completely avoiding equipment downtime risks. The output is a pure sine wave with a distortion rate below 3%, effectiveolating grid interference to provide clean and stable power for precision communication and monitoring equipment, ensuring device safety and data integrity.

(3) Intelligent O&M Design: Equipped with LCD Chinese touch operation interface, the process is intuitive and operation is simple. It supports Ethernet communication interfaces and remote monitoring, allowing real-time monitoring of key parameters such as UPS operating statusery capacity. Automatic audio-visual alarms are triggered in case of failure, facilitating quick localization and timely handling by maintenance personnel, suitable for the decentralized O&M scenarios of exprssways.

(4) Quality and Energy Efficiency: Featuring an industrial-grade protective structure that is dustproof and moisture-proof, it is suitable for the outdoor expressway server room working enviroment of -10℃ to 50℃, ensuring stable and durable equipment operation. Ad
