Deeply showcase Delta's one-stop green and energy-saving solution covering power supply, heat dissipation, monitoring, and intelligent management. Delta's Green Power Supply Solution for High Energy Consumption Manufacturing Industry
The fields of copper foil, chemical foil, and non-ferrous metal smelting in Qinghai are typical high energy consuming DC loads in traditional manufacturing. Generally, one workshop has a scale of>50MW, and the entire factory is mostly in the hundreds of MW range. The three major pain points of "difficult harmonic control, high energy efficiency loss, and frequent downtime due to faults" are the main bottlenecks restricting the large-scale implementation of green manufacturing in Qinghai. In response, Delta's industrial grade green power supply system breaks through the bottleneck of traditional transformers, using transformers+UPS+medium and low voltage distribution+rectifiers to achieve 10kV AC to 800V DC conversion, helping high energy consuming manufacturing industries improve quality and efficiency, as well as green and low-carbon transformation.

Delta ESG Zero Carbon Park Comprehensive Solution
The proportion of new energy installed capacity in Qinghai Industrial Park exceeds 73%, but the volatility of wind and solar power generation, which generates electricity day and night, is seriously mismatched with the 24-hour stable electricity demand in the park. In response, Delta has created an ESG zero carbon park comprehensive solution based on the iCMS digital intelligent management platform as the digital base and core brain, integrating building automation, digital center, and smart microgrid systems, relying on the advantages of clean energy in Qinghai,Build a full chain carbon intelligent control system, achieve carbon measurement, tracking, optimization, carbon neutrality closed-loop management, accurately calculate carbon footprint, and solve the dual problems of green electricity consumption and carbon compliance.
Source grid load storage DC synergy
SST solid-state transformers have millisecond level power regulation and four quadrant operation capabilities, and can be widely connected to distributed energy sources such as photovoltaics, energy storage, and fuel cells. They are equipped with EMS smart energy management platforms to build an integrated DC microgrid with intelligent regulation.
Carbon tracking and precise analysis
Connect the underlying IoT data to achieve real-time tracking of carbon footprint and energy consumption; By analyzing energy consumption and load structure from multiple dimensions, accurately locate energy-saving and carbon reduction space.
Carbon prediction and collaborative scheduling

Delta AI Data Center Infrastructure Solution
The electricity consumption of data centers is growing rapidly, and Qinghai is building a national level green computing power base. High altitude can cause poor heat dissipation and accelerated equipment loss, and AI chip pulse loads have strict requirements for power supply stability. Delta uses SST solid-state transformers as its core,Develop a full chain AI data center power solution from the power grid to the chip, suitable for Qinghai's green electricity and cool climate, with low-carbon and high reliability computing power base.

Minimalist deployment
The SST solid-state transformer will be fully equipped for the power supply and distribution system, with input cabinets, power cabinets, and output cabinets prefabricated in an integrated manner, and the entire machine will be tested in the factory; Compared to traditional on-site assembly with a delivery cycle of no less than 10 weeks, SST only requires1 weekThe deployment can be completed, and the construction of the factory and equipment installation can be carried out in parallel, with early production and early returns.
From the former highland "treasure trove of scenery" to the zero carbon "smart computing new city" that gathers computing power, talent, and green power resources, Qinghai is driving the leapfrog development of the computing power industry with its advantages in green power. Delta looks forward to working with partners from all walks of life to empower the green computing power base of the plateau with innovative power electronics technology, and comprehensively enhance the core competitiveness of Qinghai's "East Data West Computing" clean energy hub!
