Copper winding step-down oil immersed transformer

Our technology: What makes us different?

SHZHEL uses the most advanced production technologies and the most demanding control systems to guarantee the highest product quality and total product reliability.

Component Description

Transformer 3-phase 10kv 11kv 1200kva 1500kva copper winding step-down oil immersed transformer 9

01 Windings

Windings are composed of two parts, namely, a conductor and insulation material. For the conductor, Hyosung uses high grade electrolytic copper or aluminium. SHZHEL Oil immersed transformers obtain high thermal capacity with the use of Epoxy coated Insuldur Kraft Paper, which has higher short time overload capacity than any other Kraft paper type.

02 Winding Support System

Coils are sized and clamped by being pressed with a special hydraulic fixture after assembly with the core. With Axial and Radial direction, we reinforce the winding support system. This secure structure helps withstand harsh short circuit forces.

03 Core

Core design is essential because it determines the transformer’s efficiency and noise level. For high dimensional accuracy, the core cutting processing of SHZHEL is controlled by a computerized system. By Step-Lap core stacking, SHZHEL Oil immersed transformers attain to optimal characteristics for each customer.

04 Heat dissipation corrugated sheet

The transformer will be equipped with heat dissipation corrugated sheets to ensure that the temperature rise of the winding or oil does not exceed the specified limit when the transformer is operated continuously at rated full load.
