Three-Phase Oil-Immersed Silicon Steel Laminated Core Transformer

The laminated core transformer adopts high magnetic permeability and low-loss silicon steel sheets, with a stepped multi-stage joint structure. The core tensioning and clamping use anti-loosening structures. The cross-section of the transformer core is oblong, which can reduce the height of the core yoke, thereby lowering the overall core height of the transformer, saving silicon steel sheets, oil tanks and other steel materials, as well as transformer oil consumption.

The oil tank is a corrugated rectangular tank. And the corrugated sheets are automatically welded by robots, ensuring full, smooth, flat and uniformly thick weld seams to prevent oil leakage. The elasticity of the corrugated sheets can compensate for the volume change of transformer oil caused by temperature variations.

①High-voltage power transmission networks ;

②Large industrial loads (e.g., high-voltage power transformers in steel plants and aluminum smelters, which need to withstand impact loads);

③Outdoor public substations (cost-sensitive areas with diverse capacity requirements).

Advantages

Except for small-capacity models that use copper conductors, low-voltage windings generally adopt a cylindrical structure with copper foil wound around the shaft. High-voltage windings use a multi-layer cylindrical structure, which ensures balanced ampere-turn distribution of the windings, low leakage flux, high mechanical strength and strong short-circuit resistance.

By replacing the oil conservator with corrugated sheets, the transformer oil is isolated from the outside environment. This effectively prevents the entry of oxygen and moisture, which would otherwise degrade insulation performance, and extends the service life of the transformer.
