24MVA 20MVA Power Transformer 110KV 115KV 132KV Three Phase Oil Immersed Transformer

Product Description

Our 20MVA & 24MVA three‑phase oil immersed power transformer is engineered for high‑voltage transmission and distribution networks, covering rated voltage levels of 110kV, 115kV and 132kV. Manufactured in full compliance with IEC, ANSI and IEEE standard, this power transformer adopts premium grain‑oriented silicon‑steel core and high‑performance insulated windings, fully submerged inside a sealed steel tank with mineral insulating oil acting as both cooling and dielectric medium. Multiple cooling modes including ONAN and ONAF are available to match different load conditions. Each unit passes complete type test and routine test to guarantee stable long‑term operation for high‑capacity power systems. Custom‑built solutions for voltage ratio, vector group and protection accessories are supported upon client requirements.

Core Purpose

As key transmission equipment, the 110kV‑132kV oil‑immersed power transformer mainly executes step‑up and step‑down voltage conversion. It transfers large‑capacity electric power between high‑voltage transmission lines and medium‑voltage distribution networks, stabilizes grid voltage, realizes safe power energy transmission, and connects power generation sources to regional power grids. This 20MVA / 24MVA power transformer undertakes core power conversion tasks for substations to balance power flow and reduce transmission loss across the whole power system.

Application Scenarios

This 24MVA 20MVA power transformer 110KV 115KV 132KV three‑phase oil immersed transformer serves a wide range of projects. It is widely deployed in utility main substations, urban power grid reconstruction and expansion, large‑scale solar and wind renewable‑energy power plants for grid‑connection boosting. It also fits heavy‑duty industrial complexes, mining sites, port power stations and large infrastructure projects. Suitable for outdoor substation installation, it adapts to diverse climate and environmental conditions for both new‑build and upgrade power projects.
