Document Published: 2026-07-22 Last Updated: 2026-08-03

Project Introduction

GoWatron supplies all secondary equipment for the Palut 110kV Central Substation and the Kamaza 110kV Substation in Tajikistan, including the complete electrical supervision and control systems.
Project Location: Palut, Republic of Tajikistan.

Application Highlights

The gold mining project invested by China Nonferrous Mining Corporation Limited in Palut, Tajikistan, is a major mining asset of China Nonferrous Metal Mining (Group) Co., Ltd. in Central Asia. It was one of the largest investment projects undertaken by Chinese central state-owned enterprises (SOEs) in Tajikistan at that time, and serves as a landmark industrial project under China Nonferrous Group’s implementation of the Belt and Road Initiative.
