From Silicon Steel to Solid Core: How We Build Every Transformer Core
A transformer’s core starts as flat silicon steel sheet. Here’s exactly how we cut, stack, clamp, varnish and bind it into a finished core.
Transformer Core History: From Wrought Iron to Amorphous Alloys
Every transformer core alive today carries over 140 years of trial and error inside it. This article traces that history — from the first laminated wrought-iron core in 1884 to hot-rolled and grain-oriented silicon steel, HiB grades, laser-scribed domains, and today’s amorphous and nanocrystalline alloys — and shows how each material and structural breakthrough cut core losses, and why it still matters when you’re specifying a transformer.
Key Differences Between China and EU Transformer Energy Efficiency Ratings
What are the key differences between China’s GB 20052-2024 and the EU’s 548/2014 transformer efficiency standards? A practical breakdown of voltage classes and loss limits for 10kV oil-immersed and dry-type distribution transformers.
Chengdu Xinjin Fangxin 10MW/h User-Side Energy Storage Project
Zhongxin General has delivered Chengdu’s first 10MW/h user-side battery storage project, installed at a manufacturing site in the Xinjin Economic Development Zone. Running on a “two-charge, two-discharge” schedule, the system is already saving the client close to RMB 1 million a year — and it’s drawn site visits from two of the city’s leading power-industry associations.
5.175MW/10.03MWh User-Side Battery Storage Project Goes Live at Towngas LNG Facility — Weiyuan, Neijiang
Zhongxin General’s first user-side energy storage project — a 5.175MW/10.03MWh containerized BESS built for a Towngas LNG facility in Weiyuan — is now online and generating stable returns.
Distributed PV Project for Sichuan China Tobacco’s Shifang Cigarette Factory — Shifang, Sichuan
Zhongxin General delivered four box-type substations (3×1250kVA + 1×2500kVA) with self-manufactured SCB14 dry-type transformers for a distributed photovoltaic project at Sichuan China Tobacco’s Shifang cigarette factory — grid-connected July 14, 2026.
Zhongxin General Showcases Full-Chain Power Solutions at the 2026 China Smart Energy Conference, Chengdu
Zhongxin General brought its full transformer, switchgear and energy-storage lineup — plus its self-developed virtual power plant platform — to the 2026 China Smart Energy Conference in Chengdu, hosting delegations from India, Mongolia and beyond.
Transformer Connection Types Explained: From Basics to Application — Understanding Vector Groups in One Article
Star or delta? Yyn0 or Dyn11? This guide breaks down how transformer vector groups work — the two basic winding connections, the clock-position notation used on nameplates, and why Dyn11 has become the default choice for modern distribution transformers — so you can read a nameplate with confidence and specify the right connection for your project.
What are the differences between dry-type transformers and oil-immersed transformers and how to choose
Not sure which transformer fits your project? This guide breaks down the real differences between dry-type and oil-immersed transformers — fire safety, maintenance, cost, and where each performs best.
