Why Ultra-Low Burr Control Matters in CRGO Cores

In transformer core production, many buyers focus first on CRGO grade, core loss value, magnetic induction, and coating type. These are all important. However, one small detail is often overlooked during slitting and cutting: burr level. For transformer laminations, burrs may look minor, but they can affect stacking quality, interlaminar insulation, core loss, and long-term

AI Ends at Power—Transformers and Silicon Steel Matter

A sheet of silicon steel, thinner than two A4 papers, is quietly holding back global AI giants. While engineers in Silicon Valley are still struggling to push the parameter limits of next-generation large models, an unexpected bottleneck has already emerged—not chips, not algorithms, but electricity. More precisely, it is the “heart” that delivers electricity safely

Global Transformer Shortage to Last Until 2029

The world is entering a prolonged phase where power transformer supply simply can’t keep up with demand. This isn’t a short-term demand spike. Instead, it’s a full-blown capacity, delivery, and labor crunch. Grid upgrades, generation growth, and surging data center loads are all falling behind schedule because of it. According to the Zhuifeng Trading Desk, analyst

The Silicon Steel Opportunity in U.S. Grid Expansion

Table of Contents 1. The Booming Demand for Silicon Steel Driven by U.S. Grid Expansion In recent years, the U.S. power system has faced three major challenges. These include aging infrastructure, surging electricity demand, and the urgent need to switch to cleaner energy. Grid expansion and upgrades have become essential to address these issues. 1.1
