27Q110, B27P100, B27R085 CRGO Silicon Steel Coil & Sheet

27Q110, B27P100, B27R085 CRGO Silicon Steel Coil & Sheet | Grain Oriented Electrical Steel

Ultra-low core loss reduces transformer energy consumption
Excellent magnetic permeability for stable magnetic performance
0.27mm thin thickness, compact transformer design
Uniform insulation coating, good stacking factor
Stable mechanical property, easy slitting & cutting

Product Overview

27Q110, B27P100 and B27R085 are 0.27mm thickness cold rolled grain oriented (CRGO) silicon steel, widely used for power transformers, distribution transformers, inductors and reactors.

These grades feature low iron loss and high magnetic induction. The surface is coated with inorganic tension insulation coating to reduce magnetostriction and noise. We supply both coils and cut-to-size sheets. Custom slitting, cutting and packaging are available for global transformer manufacturers. Strict factory inspection ensures consistent magnetic and mechanical performance for high voltage & medium voltage transformer core application.
