The Beginning of Everything-RAW MATERIAL
Raw materials and components sourced from our own factory or verified reputable vendors (e.g., MR, ABB, Huaming, GE)

Raw materials and components sourced from our own factory or verified reputable vendors (e.g., MR, ABB, Huaming, GE)
01
Sheet-Metal Processing
CNC/laser cutting and precision bending produce dimensionally accurate panels; edges are deburred and features verified to drawings with part-level traceability..
02
Robotic Welding
Robotic MIG/TIG/spot welding in dedicated fixtures delivers uniform seams with minimal distortion; earthing studs and reinforcements are applied, then flatness and diagonal tolerances are confirmed.
03
Surface Treatment
Degreasing and phosphating/shot-blasting precede electrostatic powder coating; curing, DFT/adhesion tests, and gasket installation secure the specified IP/IAC protection.
Busbar Processing
Busbar Raw-Material Processing
Copper bars are sheared/punched/drilled and CNC-bent on an automatic busbar center with repeatable accuracy; edges are radiused, joint faces cleaned, and phase/position markings applied to meet clearance/creepage requirements.
Busbar Plating
Tin/silver plating or epoxy insulation coating is applied per specification; thickness and dielectric strength are verified, heat-shrink boots fitted, and stacks labeled for assembly.
Primary Assembly
Primary Component Installation
Circuit breakers/switches, CTs/PTs, surge devices, shutters, and barriers are mounted; interlocks are set, earthing is bonded, and torques follow the approved chart and IEC.
Busbar System Installation
Install main, vertical, and branch busbars to drawings; secure with rated insulators/clamps; torque-verify low-resistance terminations to primary devices, limiting temperature rise and losses.
Secondary Wiring
Wire Harness Processing
A 3D-driven, fully automated line that cuts, strips, applies number tubes, selects terminals, crimps, and heat-shrinks secondary wires—delivering consistent process quality and higher production efficiency.
Wiring Termination
Wiring is routed in trunking with bend-radius control and crimped using calibrated tools; relays/meters/PLC/RTU and terminal blocks are installed, labeled, and configured (settings/comms).
Inspection & Commissioning
Mechanical Characteristics Check
Visual/dimensional audit, door fit, drawer racking, and interlock sequence verification; earthing continuity and torque spot-checks logged.
Electrical Tests
Insulation resistance and power-frequency withstand (HiPot); MV partial-discharge as applicable; primary/secondary injection and full functional checks complete FAT.
