Project Background and Significance
The sand plant of Minjiang Industry Co., Ltd. in Aba Tibetan Autonomous Prefecture, Sichuan Province, is a key ecological governance and infrastructure supporting project in Sichuan Province. Located in the ecological barrier zone of the upper reaches of the Yangtze River, it undertakes tasks such as river dredging and sand and gravel aggregate production, providing important support for local water conservancy construction and ecological protection. The construction of two new 2000kVA prefabricated substations is the core power supply facility for the sand plant, requiring highly reliable, intelligent, and low-carbon power supply for high-energy-consuming equipment such as crushers, screening equipment, and sewage treatment systems. The project is located on a plateau with harsh climatic conditions, placing extremely high demands on the environmental adaptability and long-term stability of the power distribution equipment.
Leveraging its technological strength in intelligent power distribution and experience in ecological governance projects, Shanghai Zikai Electric Co., Ltd. provided the project with a complete set of core power distribution equipment and system solutions, and successfully completed the power transmission, helping Minjiang Industry build a safe, efficient, and sustainable energy supply system.
Project Highlights and Contributions of Zikai Electric
High-reliability intelligent prefabricated transformer at high altitudes
To meet the extreme requirements of the sand plant for continuous power supply, Zikai Electric designed a dual-circuit + intelligent backup power switching (ATS) system, which includes core equipment such as a 2000kVA box-type substation, high-voltage switchgear, and intelligent circuit breakers, to ensure "zero interruption" in key processes such as crushing and sorting.
Digital protection devices are used to achieve millisecond-level fault location and automatic recovery, ensuring the safety of equipment and personnel.
Intelligent monitoring and energy efficiency optimization
An integrated IoT monitoring platform monitors device status, power quality, and load distribution in real time. Through AI algorithms, it dynamically adjusts power supply strategies, which is expected to reduce line loss rate to below 3% (data example).
It reserves access ports for photovoltaic/energy storage systems, enabling future expansion of clean energy applications and helping enterprises achieve carbon neutrality goals.
Adaptability to harsh environments
The equipment has passed IP67 protection certification and can withstand extreme temperature differences (-20℃ to 40℃), high altitude, low oxygen and strong ultraviolet environment in plateau areas, with the life of key components extended to more than 25 years.
Strictly adhering to State Grid technical specifications, it supports "one-click start/stop" and remote operation and maintenance, reducing the difficulty of operation and maintenance in high-altitude areas.
Customer testimonials and regional value
The head of Minjiang Industrial Co., Ltd. in Aba Tibetan Autonomous Prefecture, Sichuan Province, stated, "Zikai Electric's intelligent transformer substation system not only far exceeded our expectations in terms of technological advancement, but its professional team also collaborated efficiently throughout the entire process, from scheme design to power transmission, fully ensuring the project's progress and quality. This cooperation has laid a solid foundation for our intelligent upgrade in the field of plateau ecological governance!"
The successful power transmission of this project marks an important step forward for Sichuan Province in the coordinated development of the Yangtze River protection and the green sand and gravel industry, providing a replicable model for ecological restoration and resource development in western China.
Zikai Electric: Protecting Green Mountains and Clear Waters with Technology
