ZHIXIN Electric in North America置信电气 · 北美

Every AI data center depends on transformers, switchgear and substations to bring power from the grid to its servers. That makes power equipment a core layer of AI infrastructure, and a natural extension of LFI's focus on AI and related technologies. ZHIXIN is our equipment partner in this area.每一座 AI 数据中心，都离不开把电网电力送到服务器的变压器、开关设备和变电站。电力设备因此是 AI 基础设施的关键一环，也与 LFI 在 AI 及相关科技领域的投资方向一脉相承。置信电气是我们在这一领域的设备合作伙伴。

About ZHIXIN关于置信电气

ZHIXIN is one of the world's leading manufacturers of amorphous alloy transformers. Since its founding in 1997, the company has focused on low-loss transformer technology, and it built the world's first 8 MVA power transformer with a 3D-wound amorphous core. Compared with conventional silicon-steel designs, amorphous cores cut no-load losses substantially – savings that add up quickly at data centers and commercial and industrial sites that run around the clock.置信电气是全球领先的非晶合金变压器制造商之一。公司自 1997 年成立以来专注于低损耗变压器技术，研制出全球首台 8 MVA 立体卷铁心非晶合金电力变压器。与传统硅钢铁心相比，非晶铁心能大幅降低空载损耗；对全天候运行的数据中心和工商业用户来说，节省的电费相当可观。

What we supply供应产品

For North American projects, LFI focuses on three product lines:面向北美项目，LFI 主推以下三类产品：
