Overview
On June 10, 2025, the Hami – Chongqing ±800 kV UHVDC transmission project of State Grid Corporation was officially put into operation. As a core project of the national “West – East Power Transmission” initiative, the project passes through deserts, mountains, and regions with complex climates, imposing extreme requirements on the corrosion resistance, mechanical strength, and stability of transmission equipment. SH Power deeply participated in the project and provided key technical support for critical nodes. The project will significantly enhance Chongqing’s power supply capacity and holds great importance for optimizing the allocation of energy resources in the western region, achieving the “dual – carbon” goals, and promoting coordinated regional development.
As a key equipment supplier for the project, SH Power provides the following products and services:
| Application Scenario | Product Name & Model | Technical Specifications |
| Gobi Desert Conductor Suspension | Aluminum Alloy Forged Suspension Clamp (XGD-25/70-50) | Nominal breaking load: 250 kN; Grip strength ≥24% of conductor breaking load; Salt spray corrosion resistance life >30 years |
| High-Wind Zone Galloping Control | Six-Bundle Anti-Galloping Spacer (FSD-6X) | Galloping amplitude reduction: 70%; Conductor displacement <1.5 m under Beaufort scale 12 winds (32.7–36.9 m/s) |
