Engineering Innovations

Magnetic Core Design

• Material: 30-0-130 grain-oriented electrical steel

• Noise Control: Chip-removed cores with polymer curing (≤70dB)

• Adjustability: Precision air gap adjustment (vertical/horizontal)

Structural Features

• Dual epoxy resin tubes with stainless steel brackets

• Grounding shields between windings and core

• Thermal expansion compensation for oil system

• 60+ years design life with 200,000 operations

Typical Applications

• GIS Testing: 420kV~1100kV gas-insulated switchgear

• Transformer Tests: Power transformer routine and type tests
