Outdoor Threephase Transformer

For reliable power distribution in demanding outdoor environments, our Outdoor Oil Immersed Transformer offers a robust and time-tested solution. These units are engineered for resilience against harsh weather conditions, temperature fluctuations, and long-term outdoor exposure. The core design utilizes advanced grain-oriented silicon steel laminations, significantly reducing no-load losses and ensuring high energy efficiency. They are ideally suited for utility substations, industrial parks, remote construction sites, and renewable energy farms where dependable voltage transformation is critical. As a premier type of Threephase Electric Transformer, it provides balanced and stable three-phase power, making it the backbone of modern electrical grids and large-scale commercial power systems.
The **Outdoor Threephase Transformer** is meticulously manufactured to exceed international standards, including IEC, IEEE, and ANSI. It features a fully sealed tank construction with high-quality welded seams, preventing moisture ingress and preserving the integrity of the insulating oil. The tank is treated with a multi-layer corrosion-resistant coating to withstand UV radiation, rain, snow, and saline atmospheres. Key internal components, such as the windings, are made from electrolytic copper or aluminum, chosen for optimal conductivity and mechanical strength. The transformer is equipped with essential accessories like a conservator tank with a silica gel breather to maintain oil purity, a Buchholz relay for internal fault protection, and pressure relief devices for operational safety. Its design prioritizes not only performance but also longevity and minimal maintenance requirements in the most challenging outdoor installations. **Key Product Specifications:** * **Standard Compliance:** IEC 60076, IEEE C57.12.00, ANSI C57.12.10 * **Phase:** Three-Phase * **Cooling Type:** ONAN (Oil Natural Air Natural) * **Insulation Class:** A (105°C temperature rise) * **Frequency:** 50Hz / 60Hz * **Winding Material:** Electrolytic Copper / Aluminum * **Core Material:** High-grade, grain-oriented silicon steel * **Protection Degree:** IP55 (Dust-proof and jet water resistant) * **Tap Changer:** Off-circuit tap changer (typically ±2x2.5% or ±5%) * **Accessories:** Conservator tank, Silica gel breather, Buchholz relay, Pressure relief device, Dial-type thermometer, Lifting lugs, Jacking pads. **Standard Technical Parameters Table:**
