Manufactured from premium CRGO grain-oriented silicon steel, each split tape-wound U-core starts as a continuously wound solid blank before high-vacuum stress-relief annealing and precision straight cutting into a matched set of two identical U-shaped halves. As a versatile cut tape-wound U-shaped core, it shares the assembly convenience of other split wound cores while offering gentler rounded transitions at the bends, reducing localized flux crowding and lowering the risk of insulation damage during coil fitting.
Every set of this two-piece tape-wound U-core, widely known in procurement documents as wound U-core or silicon steel split U-core, is dimensionally inspected and magnetically paired prior to packing. This pairing ensures consistent inductance across mass production runs. As a practical reactor U-core, it supports independent coil winding off the core, eliminating difficult through-window winding workflows and helping OEMs optimize labor time and production throughput.

Q1: What differentiates split tape-wound U-core from split tape-wound C-core? A1: The main distinction lies in the profile. Our split tape-wound U-core adopts smooth rounded corners, which reduce flux crowding and simplify coil placement. C-type split cores typically have sharper right-angle corners. Both support pre-wound coil assembly and are available in matched pairs for reactor use.
Q2: Are wound U-core sets tested and matched before shipment? A2: Yes. Each two-piece tape-wound U-core undergoes magnetic matching and dimensional inspection. This process keeps inductance variation low across batches and avoids uneven performance once assembled into finished reactors.
Q3: Can I customize sizes, coating and silicon steel grades for this silicon steel split U-core? A3: Full customization is supported. We adjust core geometry, steel thickness, surface insulation and machining tolerances according to customer drawings, electrical targets and enclosure constraints.
Q4: Can you provide material certificates and test records for the reactor U-core? A4: We supply original mill certificates for CRGO steel, batch dimension reports and core loss test data. These documents can be used for internal quality audits and third-party equipment certification.
