S13 2000KVA 10/0.4KV Oil - Immersed Power Transformer
Introduction
The S13 2000KVA 10/0.4KV oil - immersed power transformer is a high - performance electrical device designed to efficiently transform electrical energy between different voltage levels. With its advanced technology and reliable design, it plays a crucial role in power distribution systems, ensuring a stable and safe power supply.
Technical Features
Core Design
The core of the S13 power transformer is made of high - quality cold - rolled grain - oriented silicon steel sheets. These sheets are carefully laminated to reduce eddy current losses and hysteresis losses. The low - loss core design not only improves the overall efficiency of the transformer but also reduces heat generation, extending the service life of the equipment.
Winding Structure
The windings of the transformer are made of high - purity copper conductors. The primary winding is designed for a rated voltage of 10KV, while the secondary winding is for 0.4KV. The copper windings have excellent electrical conductivity and mechanical strength, which can withstand short - circuit currents and ensure reliable operation under various load conditions.
Oil - Immersed Cooling
This power transformer uses oil - immersed cooling technology. The transformer oil serves as both an insulating medium and a cooling medium. It effectively dissipates the heat generated during the operation of the transformer, ensuring that the temperature of the transformer remains within a safe range. The oil also provides protection against moisture and oxidation, enhancing the insulation performance of the transformer.
