This is a three phase oil immersed distribution transformer delivered to Zimbabwe in 2025, the rated power is 1200KVA & 1600KVA and primary voltage is 11KV with IEC standard.
Product Introduction
A distribution transformer is an essential device in the power system, primarily used to convert high voltage electrical energy into low voltage for residential and commercial users.
FUNCTIONS:Voltage Conversion: Converts high voltage (e.g., 10kV or 35kV) to low voltage (e.g., 220V or 380V).
Current Distribution: Distributes power to different loads and users.
ADVANTAGE:Enhances the safety and reliability of the power system.
Reduces energy loss and improves power transmission efficiency.
YAWEI 1200KVA & 1600KVA 3 phase transformer was delivered to Zimbabwe in 2025. It is a Step Down transformer from 11kv to 0.669kv, the primary voltage is 11kv, the secondary voltage is 0.669kv. We can supply both Step Up and Step-Down transformer, the cooling method is ONAN. Our distribution transformer was designed with advanced technology and adopts high quality material and components which result in reliable quality and long service time.
YAWEI ensures that each one of our delivered transformer had passed the full acceptance test before shipping and we remains 0 fault rate record for more than 10 years so far, oil immersed power transformer is designed in accordance with IEC, ANSI and other major international standards.

Technical Specification
Transformer Manufacturing
Iron Core
Winding
1. Enamelled magnetic copper or aluminum wire is produced by Nantong Budweiser, which is a 100% subsidiary company belongs to YAWEI.
2.Our windings are made of high quality copper.
3.Both High Voltage (HV) and Low Voltage (LV) windings are done using Coil Winding Machines. The Copper or Aluminum strips/wires used in winding are meticulously selected for its quality to give the best output. The Copper or Aluminum strips/wires are paper covered and acts as insulators.
Oil Tank
1. Oil tank is produced by Nantong Zhihe, which is also a 100% subsidiary company belongs to YAWEI.
2. The oil tank is a power transformer housing containing the iron core, winding and transformer oil.
3. The corrugated tank structure is fully sealed, and the corrugated will expand and compress with the increase of oil, isolating the transformer from the atmosphere and preventing oil deterioration and moisture. After oil removal, rust removal and phosphating treatment, the surface of corrugated oil tank is coated with rainproof paint. Moisture and salt spray.
