In detail
How we build it, and where it fits
A core assembly kit is the core delivered the way a transformer plant actually wants to receive it: stacked, clamped and checked, with the top and bottom clamps, tie plates, insulation blocks and earthing strip already mounted. Your winding shop takes the crate off the truck and starts setting coils the same day — no stacking jig, no on-site pressing, no rework.
Every kit is 100% dimension-checked so the coil-to-core fit stays within 1 mm, and cores are loss-sampled before release. Clamping is by through-bolts or steel banding depending on the design; frames are phosphated and painted for the journey. Packing is a vacuum moisture barrier inside a fumigated plywood crate, which is what keeps a core true after six weeks at sea.
