SHENGLIN Closed Cooling Towers for UHVDC Converter System

Date:2026-09-28

Project Overview

Ultra high voltage direct current transmission systems require reliable and precise cooling equipment to protect critical converter valves during continuous full load operation. Standard cooling towers struggle to maintain stable cooling performance for high voltage converter equipment, risking valve overheating and power transmission instability. To meet the rigorous cooling demands of an ultra high voltage direct current transmission project in China, SHENGLIN delivered customized closed type cooling towers.
These closed cooling towers are specially engineered for the external cooling system of converter valves, providing stable and efficient heat rejection. Fully compliant with local 3P/380V/50Hz power standards, they deliver continuous and reliable cooling, ensuring safe and stable operation of the UHVDC transmission system throughout the year.

Project Features

UHVDC converter stations operate 24/7 with high value electrical equipment, placing strict requirements on cooling stability, water quality protection and long term equipment reliability. Ordinary open cooling towers cannot provide the closed loop water circulation needed for converter valves, easily causing contamination, scaling and unstable heat transfer that threaten equipment safety.
SHENGLIN’s tailor made closed cooling towers are fully optimized for converter valve cooling conditions. The closed structure isolates circulating water from ambient air, achieving efficient, stable and anti corrosion heat exchange. They perfectly protect the cooling medium from contamination, ensuring precise temperature control for high voltage converter equipment.
The unit is highly compatible with China’s local 3P/380V/50Hz power grid, running stably without additional power conversion devices. With optimized internal circulation and heat exchange structure, it maintains consistent rated cooling performance, effectively preventing converter overheating risks and greatly reducing long term operation and maintenance costs for the project.
 

Project Significance

This successful deployment in China verifies SHENGLIN’s professional capability to customize closed cooling towers for ultra high voltage power transmission scenarios, and proves the excellent cooling stability, water protection performance and operational reliability of our cooling systems under demanding power grid conditions. Leveraging mature industrial cooling R&D and manufacturing experience, SHENGLIN will continue optimizing cooling efficiency and system durability, providing professional and cost effective cooling towers for global power transmission and high voltage electrical projects.
