1. Project Overview
Project Name: 35kV Current-Limiting Reactor for Van Phong 500kV Substation
Project Summary: PowerMore successfully supplied and installed a 35kV Current-Limiting Reactor (CLR) for the Van Phong 500kV Substation. The equipment was successfully energized in November 2022, contributing to the safe and reliable operation of the substation’s electrical system.
Industry / Sector: Power Transmission / Substation / Medium-Voltage Electrical Equipment
Project Type: Supply and installation of a short-circuit current-limiting reactor
Voltage Level: 35kV
Location: Van Phong 500kV Substation
Energization Date: November 2022

2. PowerMore’s Scope of Work
For this project, PowerMore was responsible for the following key scopes:
- Supply of the 35kV Current-Limiting Reactor for Van Phong 500kV Substation.
- Installation of the reactor at the substation’s medium-voltage level.
- Commissioning and putting the equipment into operation following installation completion.
3. Project Highlights & Value
The Van Phong 500kV Substation is designed with two 500/220kV – 900MVA power transformers. Its associated 220kV transmission connections have a total length of approximately 26.2 km, including two circuits connecting the Van Phong 500kV Substation to the Van Phong 220kV Substation and two circuits connecting to the existing Van Phong – Tuy Hoa 220kV transmission line.
Together with the Van Phong – Vinh Tan 500kV transmission line project, the Van Phong 500kV Substation plays an important role in strengthening the electricity supply for Khanh Hoa Province and neighboring areas. The project also supports the socio-economic development of the South Central Coast key economic region while facilitating power evacuation from the Van Phong 1 BOT Thermal Power Plant and renewable energy projects in Ninh Thuan, Khanh Hoa, and Phu Yen.
At the Van Phong 500kV Substation, the high-capacity 500kV transformers contribute to significant short-circuit power levels within the electrical system. The installation of a 35kV Current-Limiting Reactor is therefore an important measure for limiting short-circuit current at the substation’s medium-voltage level.
PowerMore successfully supplied and installed the short-circuit current-limiting reactor for the project. The equipment helps improve system protection capability and contributes to the safe, stable, and efficient operation of the electrical system at Van Phong 500kV Substation.
