This video compares equal-length circular core limbs: at the same loss per unit volume, doubling the diameter gives four times the heat generation and twice the side surface area. It connects this geometry to cooling ducts, open flow paths, spacer pressure and net steel section.https://www.youtube-nocookie.com/embed/xR5jX0obvRs552026-10-29T00:00:00+00:00https://chenfanelectric.com/engineering-videos/transformer-core-single-point-earthing/https://chenfanelectric.com/wp-content/uploads/2026/10/cf-engineering-005-landscape-cover-1024x576.jpgWhy Transformer Cores Use One Intended Earthing PointThe intended core earthing path controls electrical potential. This video follows how an unintended second contact can form a conducting loop through the core, frame and tank. When changing magnetic flux links the loop, circulating current can cause local heating. It also covers assembly checks, core-to-frame insulation and electrical testing.https://www.youtube-nocookie.com/embed/UZoeGtJIVXo532026-10-29T00:00:00+00:00https://chenfanelectric.com/engineering-videos/core-limb-banding-through-bolt-design/https://chenfanelectric.com/wp-content/uploads/2026/10/cf-engineering-004-landscape-cover-1024x576.jpgCore Limb Bands vs Through-Bolts: Compare the Complete DesignThis video examines how through-holes affect the steel section, local flux paths and electrical insulation of a transformer core. It compares through-bolt arrangements with glass-fibre limb bands, including material selection, band tension and spacing within the complete core design.https://www.youtube-nocookie.com/embed/330OEEddrjE472026-10-29T00:00:00+00:00https://chenfanelectric.com/wp-content/uploads/2026/10/cf-engineering-004-shorts-cover-576x1024.jpgCore Limb Bands vs Through-Bolts: Compare the Complete DesignThis video examines how through-holes affect the steel section, local flux paths and electrical insulation of a transformer core.
