Why Choose Our 35KV Oil-Immersed Transformer?

Superior Energy Efficiency

You'll reduce operating costs significantly with our advanced core design. We use high-permeability cold-rolled silicon steel sheets with shear burrs under 0.02mm. The full bevel joint construction eliminates punching and overlapping, minimizing no-load losses and noise.

Your transformer operates quietly and efficiently, meeting modern energy standards.

Built for Durability

Our oxygen-free copper windings provide exceptional electrical performance. The rounded pad corners create uniform electric fields. For units 12,500kVA and above, unified integral support plates ensure consistent coil height. This design enhances short-circuit resistance, protecting your investment.

The corrugated oil tank structure reduces acoustic reflection, lowering noise levels. You get a cleaner, quieter installation.

Maintenance-Free Design

The capsule-type oil conservator slows oil aging dramatically. Our pointer-type oil level gauge eliminates false readings. The sealed construction isolates transformer oil from air, virtually eliminating routine maintenance needs.

You spend less time on upkeep and more time on operations.

Transportation Resilience

The robust frame structure with plate clamps and side beams creates six-point rigid positioning. Your product withstands transportation impacts without requiring core lifting inspection at the destination. This saves you considerable installation time and labor costs.

Technical Specifications

Core Components

High-Performance Core

The core construction uses full oblique joints and stepped lap joints. Double-H adhesive stacking binds the three columns and two joints into a solid, flat assembly. This reduces no-load current and transformer noise.

Robust Windings

Oxygen-free copper conductors minimize load losses. Reinforced internal supports prevent deformation under stress. The mechanical strength withstands sudden short circuits reliably.

Advanced Tank Design

Integral steel plate folded into corrugated structures by precision press machinery. The design improves heat dissipation and reduces maintenance requirements. Special sealing processing eliminates traditional leak points.

Applications

Your S11 type 35KV oil-immersed power transformer performs excellently in:

• 35kV power distribution network branches
• Small and medium-sized industrial parks
• County-level power supply systems
• Manufacturing facilities requiring stable high-voltage power
• Mining operations and heavy industry
• Commercial complexes with substantial power demands
