Product Description
Amorphous & Nano-crystalline Ribbons
We produce iron-based amorphous ribbons for distribution transformer cores.
Amorphous ribbons for distribution transformers are superior to silicon steel in energy conservation. The no-load loss of SH15 amorphous distribution transformers is 60%-80% lower than SH11 silicon steel transformers.
We also produce iron-based amorphous, cobaltbased amorphous and nanocrystalline ribbons for a
Variety of electromagnetic components in electric and electronic fields.
Application Field:
Medium frequency transformer cores in heating equipment
Toroidal gapless cores as SMPS output inductors, differential input inductors
Toroidal gapless cores as noise preventive chokes in car audio, car navigation system
Toroidal gap cores for PFC use in air conditioner, plasma TV set
High frequency rectangular cut cores as output inductors and transformers in SMPS, UPS etc.
Toroidal gapless cores as pulse transformer for driving IGBTs, MOSFETs and GTOs
Amorphous stators and rotors in high power density variable speed electric motors and generators
Characteristics:
Highest saturate induction among amorphous alloys- Reduce component volume
Low coercivity- Promote component efficiency
Low core loss- Reduce device temperature rise
Variable permeability - Satisfy the various application requirements depending on different core heat treatment
Excellent stability- Having highest serving temperature of 130° C
