CNC Machined Transformer Components We Manufacture
Transformer connection systems concentrate current and torque into small machined parts.
Our range covers the LV-HV connection path end to end, with each part tested for dimensional accuracy, conductivity and torque performance.
Many components involve cast gunmetal or bronze terminal bodies precision-machined to tight tolerances.
| Component | Materials | Typical applications |
|---|---|---|
| Transformer bushing parts | Brass, gunmetal, bronze | LV and HV bushing metal parts and hardware |
| Copper transformer spades | Copper | High-current terminal connections |
| Terminal spade connectors | Copper, brass | Winding-to-terminal connections |
| Bronze / gunmetal terminals | Cast bronze, gunmetal | Terminal bodies machined from castings |
| LV-HV assemblies | Copper, brass, gunmetal | Complete connection assemblies |
| Terminal connector assemblies | Copper alloys | Distribution transformer terminations |
| Copper studs & machined washers | Copper, brass | Current-carrying fastening |
| Machined shafts & SS fasteners | Copper & Stainless steel | Mechanism and structural parts |
Transformer Part Materials & Grades
Copper and brass carry the current; gunmetal and bronze castings form robust terminal bodies; stainless steel provides corrosion-resistant strength.
How We Manufacture Transformer Components
Transformer hardware is a current-carrying job first and a machining job second.
Copper spades, studs and terminal connectors are CNC machined from copper for conductivity; bushing metal parts and terminal bodies are cast in bronze and gunmetal on our sand casting and shell moulding lines, then machined to final dimensions.
Contact faces are held to +/-0.01 mm (10 microns), because joint resistance and therefore operating temperature follow directly from the flatness and area of that face.
Grade selection
Copper for current paths, brass, bronze and gunmetal for bushing and terminal bodies.
Casting or bar preparation
Sand cast and shell moulded bodies, or copper and brass bar.
CNC machining
Turning, milling and drilling of contact faces, bores and mounting features.
Finishing
Deburring and any specified plating, which is in our scope.
Assembly
LV-HV and terminal connector assemblies built and checked as a set.
Inspection
Calibrated dimensional check and material verification before dispatch.
Transformer Part Manufacturing Process
Transformer hardware has to carry current across a joint that is never reopened.
Contact faces are machined flat and true, and LV-HV assemblies are built and checked as a set rather than shipped as loose parts.

Why Choose Machined Copper & Bronze Transformer Parts
A transformer terminal that runs hot ages the insulation around it, so the cost of a poor connection is the life of the unit.
Machined contact faces and correctly specified copper give you a predictable joint resistance that a formed or cast-only part will not hold consistently.
Low, predictable joint resistance - contact faces machined flat to +/-0.01 mm (10 microns).
Copper where current demands it, bronze and gunmetal where the body needs strength.
Complete assemblies - LV-HV and terminal connector assemblies supplied built, not as loose parts.
Casting and machining of bronze bodies handled by one supplier.
Made to transformer OEM drawings, including repair and spares programmes.
Material traceability - test certificates with every batch, third-party NABL reports on request.
