Ultra-low iron loss, prominent energy-saving effect

The low core loss index of 1.0W/kg at P15/50 effectively reduces long-term operating power consumption of transformers, enabling finished transformers to meet Class 1 energy efficiency standards at home and abroad, and smoothly pass grid bidding and energy-saving certification audits.

0.23mm thin gauge, supporting lightweight & miniaturized design

The 0.23mm thin thickness adapts to the miniaturization and lightweight design trend of distribution transformers, dry-type transformers and small power reactors, lowering overall equipment volume and logistics transportation costs.

 

High-performance insulating anti-corrosion coating, long service life

Uniform integrated organic insulation coating resists dampness, corrosion and aging, prolonging the service life of transformer iron cores and reducing after-maintenance costs for transformer factories.

 

 

Urban And Rural Grid Distribution Transformers

Core magnetic material for mass-produced energy-saving distribution transformers, widely used as an upgraded substitute for traditional high-loss silicon steel in grid renovation projects.

 

Low-noise Indoor Dry-Type Transformers

Preferred core raw material for environmentally friendly dry-type transformers with strict low loss and low noise requirements for indoor installation.

 

Medium & Small Complete Set Power Transformers

Commonly applied in high-low voltage complete transformer equipment, distributed small grid-connected transformers and photovoltaic supporting power transformers.

 

Energy-Efficiency Retrofit & New First-Class Efficiency Transformers

Ideal material for energy efficiency upgrading of old transformers and customized production of new first-class energy efficiency transformer products.

 

Power Reactors & Medium-Frequency Electromagnetic Components

Suitable for manufacturing filtering reactors, reactive power compensation reactors and high-precision medium-frequency electromagnetic iron cores.

Is 23AR100 slit silicon steel suitable for distribution transformer iron cores?

Absolutely. With ultra-low iron loss of 1.0W/kg and high magnetic induction performance, it is the mainstream mass-production material for energy-saving distribution and dry-type transformers, fully meeting global power grid Class 1 energy efficiency standards.

 

What is the difference between 23AR100 and ultra-high grade 23R090? 

23R090 delivers lower iron loss but comes with higher raw material and processing costs. 23AR100 balances premium magnetic performance and economic cost, making it the most cost-effective option for large-batch standard transformer manufacturing.

 

Can you supply burr-free precision slit coils of 23AR100?

Yes. We provide integrated full-process slitting, edge trimming and deburring service. The finished slit coils can be directly put into core lamination production without secondary rework, significantly cutting production costs and improving the qualification rate of finished iron cores.
