Uruguay 500kV Transmission and Substation Ring Network Closure Project

Overview

The project spans five provinces in northern Uruguay. It includes the construction of a new 500kV substation, the expansion of an existing 500kV substation, and a single-circuit transmission line that is 355 kilometers long. Our company, as an outstanding supplier, provides a full series of fitting solutions for the project, covering transmission lines, substations, and guy wire systems for poles and towers. The specific products include power fittings, substation fittings, pole and tower guy wire fittings, and ground anchors, all of which are key products. The products have passed the ISO 9001 quality certification and the acceptance of the IEC 61284 international standard.

Power Fittings (for transmission lines):

• High strength and corrosion resistance: Utilizing a hot-dip galvanizing + aluminum alloy composite process, these fittings are adapted to Uruguay’s high-temperature and high-humidity climate with a lifespan exceeding 30 years.
• Low corona design: The surface electric field distribution of the fittings is optimized to reduce energy losses in the 500kV high-voltage transmission lines.

Substation Fittings (for GIS equipment):

• Precise fit: These fittings are designed to match the 500kV GIS equipment independently developed in China, with an installation error of ≤0.5mm, ensuring zero risk of discharge.
• Modular structure: This design supports rapid installation, reducing the substation construction period by more than 20%.

Pole and Tower Guy Wire Fittings and Ground Anchors:

• Wind and sand resistance design: Through ANSYS mechanical simulation, these fittings can withstand strong winds in South America (wind speed of 40m/s) and sand erosion.
• Eco-friendly ground anchors: Made from recyclable steel to minimize the impact on the local ecological environment.
