We are proud to serve a prestigious clientele that includes State Grid Corporation of China, Ethiopian Power, Singaporean infrastructure projects, and major energy initiatives across the globe. Our Vietnam manufacturing base provides partners with tariff advantages and cost-efficient exports to the U. S. Market, ensuring competitive pricing without compromising quality.
Our product portfolio spans three core divisions. In Power Cables, we specialize in high-temperature and energy-efficient cables designed for extreme conditions, including power grids and industrial plants, with full customization for voltage, insulation, and environmental requirements. In Transformers, we manufacture power transformers, distribution transformers, dry-type transformers, and oil-immersed transformers ranging from distribution-level to high-voltage applications, engineered for high efficiency, low loss, and long service life. In Switchgear, we produce high-voltage and low-voltage switchgear, ring main units, distribution cabinets, and motor control centers, all designed to meet stringent safety and reliability standards for substations, industrial facilities, and commercial buildings.
Our strategic manufacturing advantage lies in our dual-base operation. The Vietnam facility reduces trade barriers-particularly U. S. Tariffs-and accelerates delivery to ASEAN and EU markets, while our China operations provide scalable capacity and rapid production turnaround for large-scale projects. We maintain rigorous quality assurance throughout the supply chain, sourcing premium raw materials such as flame-retardant XLPE and mineral insulation, and operating in-house laboratories that verify conductor resistance, fire resistance, durability, and transformer/switchgear performance parameters.
Driven by our mission to empower global energy transitions with innovative, reliable, and sustainable solutions, we bridge technological excellence with real-world applications. Our vision is to become the preferred partner for high-performance electrical equipment in emerging markets and beyond, guided by four core values: Quality First, Global Collaboration, Sustainability, and Customer Trust.
