Explore our CPRI type-tested and ISO 9001 certified transformer line engineered specifically to perform under tropical ambient temperatures (up to 45°C), high humidity, and heavy industrial load profiles in Ho Chi Minh City and surrounding manufacturing hubs.
As a leading China wholesale manufacturer and technical supplier specializing in high frequency and high-voltage power distribution equipment, we provide customized transformer architecture directly tailored to the rapidly expanding industrial sectors of Ho Chi Minh City (HCMC), Bình Dương, Đồng Nai, and Long An.
Our high frequency equipment and transformer cores utilize precision-annealed silicon steel and advanced ferrite alloys, minimizing eddy current losses during high-frequency switching operations in modern industrial rectifiers and power supplies.
Engineered for the humid, salt-spray prone environment near HCMC’s Saigon River network and Cát Lái Port, our tanks feature multi-stage sandblasting, epoxy primer coating, and polyurethane topcoats rated up to ISO 12944 C4/C5 durability.
Every step-down distribution transformer is designed to seamlessly interface with EVN's 22kV/0.4kV and 11kV/0.4kV power supply networks, complying fully with Vietnamese National Standards (TCVN 6306 / IEC 60076 series).
Vietnam's Southern Key Economic Zone demands tailored electrical engineering solutions. Below are primary field application scenarios where our transformers provide continuous power stability.
In flagship industrial zones such as Tân Thuận EPZ, Linh Trung EPZ, and Saigon Hi-Tech Park (SHTP), factories operating high-density SMT electronics lines and precision CNC machinery require stable 380V/415V secondary three-phase power. Our S11-M hermetically sealed oil-immersed transformers (160kVA - 1500kVA) prevent internal oil degradation caused by high ambient humidity, providing low-noise, energy-efficient step-down capabilities that drastically lower plant operational expenditure.
For urban developments in HCMC's District 1 CBD, District 7 (Phú Mỹ Hưng), and Thủ Đức City, safety against fire hazards is paramount. Our Cast Resin Dry-Type Transformers (up to 11kV/33kV) feature flame-retardant (F1 class) self-extinguishing insulation and low noise emission, making them ideal for indoor basements, shopping centers, and sub-surface utility rooms where oil leakage risks cannot be tolerated.
Logistics hubs surrounding Cát Lái Port, SP-ITC, and Hiệp Phước Port handle constant container gantry crane loads, refrigerated container (reefer) banks, and high-duty winches. We supply custom Pad-Mounted ONAN/ONAF Transformers equipped with remote tap changer cubicles (RTCC) and automatic voltage regulators (AVR) to prevent severe voltage drop during peak motor starting sequences.
Heavy manufacturing facilities in surrounding industrial corridors (VSIP Bến Cát, Biên Hòa 2) utilizing induction heating, electroplating rectifiers, and high-frequency power switching rely on our Special Purpose Rectifier & Furnace Transformers. Designed to withstand heavy harmonic distortion and rapid thermal cycles without insulation breakdown.
Understanding the legislative and technological shifts shaping electrical procurement across Vietnam's power distribution market.
Under Vietnam’s Power Development Plan 8 (PDP8), EVN is prioritizing grid decarbonization, transmission loss reduction, and smart grid automation. Importers and contractors in HCMC are increasingly mandating transformers with lower no-load and load loss indices that conform strictly to international efficiency standards.
EVN HCMC has largely completed the conversion of legacy 6.3kV and 15kV distribution lines to the unified 22kV primary grid standard. We export wholesale 22kV primary units with dual-voltage primary options (e.g., 22kV/10kV switchable) to assist legacy factories upgrading their substations seamlessly.
Modern factory automation in Southern Vietnam relies heavily on real-time SCADA telemetry. Our transformers offer integrated PT100 temperature sensors, RS485 communication protocols, digital oil level indicators, and high-frequency noise suppression filters for industrial IoT readiness.
Building upon decades of transformer manufacturing excellence, our state-of-the-art facility combines deep engineering expertise with rigorous quality management.
Our designs are type-tested at prestigious independent laboratories, including the Central Power Research Institute (CPRI). Every individual transformer shipped to Ho Chi Minh City undergoes 100% factory routine testing in full compliance with IS 2026 / IS 1180 / IS 11171 / IEC 60076 standards, including winding resistance measurement, turns ratio verification, induced overvoltage tests, separate-source AC withstand tests, and dielectric oil breakdown testing.
Unlike off-the-shelf catalog traders, we operate a fully integrated production line with automated core-cutting machines, precision copper/aluminum foil winding units, vacuum drying ovens, and pressure impregnation (VPI) plants. We customize transformer dimensions, enclosure IP ratings (IP23 up to IP65), vector groups, and primary/secondary voltage steps to match non-standard factory retrofits in Vietnam.
