CNC Machined Line Fittings & Substation Components We Manufacture
We produce machined electrical components for power lines, panels and substations where safe current flow and structural reliability are essential. Every part is manufactured with tight dimensional control and verified on calibrated gauges.
Each component is CNC machined to customer 2D/3D drawings and samples.

|---|---|---|
| Suspension clamps | Aluminium alloys, brass | Supporting conductors on transmission/distribution lines |
| Tension clamps | Aluminium alloys, brass | Dead-end and anchor points on overhead lines |
| Hotline clamps | Brass, copper alloys | Live-line tapping connections |
| Line tap split bolts | Brass, copper alloys | Conductor tap-off connections |
| Neutral links (Neutralinks) | Brass | Panel and distribution board neutral terminations |
| Precision terminals & connectors | Brass, copper alloys | Panel and substation terminations |
| Brackets & electrical mounts | Aluminium, stainless steel | Panel and substation structural mounting |
| Heat sinks | Aluminium alloys | Thermal management in electrical assemblies |
| Interrupter cranks, shafts & spacers | Stainless steel, brass | Switchgear and interrupter mechanisms |
| Resistors, lock tabs & small parts | Brass, copper alloys | Panel and line assembly hardware |
Materials & Grades for Electrical Fittings
Material choice balances conductivity against strength. Brass, copper alloys and aluminium carry current; stainless steel provides strength and corrosion resistance for structural and mechanism parts.
How We Manufacture Line Fittings & Substation Parts
Line and substation hardware carries current and mechanical load at the same time, outdoors, for decades.
Clamps, brackets and heat sinks are CNC machined from aluminium and brass; terminals, neutral links and split bolts are turned and milled from brass and copper alloys where conductivity governs the choice.
Grade selection
Aluminium alloys for clamps and heat sinks, brass and copper alloys for current paths.
CNC machining
Turning, milling and drilling of clamp bodies, terminals and mounting features.
Thread cutting
Fastening and termination threads gauged in process.
Finishing
Deburring and any specified plating or anodising, which is in our scope.
Inspection
Calibrated dimensional check and material verification before dispatch.
Contact faces and bore centres are held to +/-0.01 mm (10 microns), since clamping force and contact area determine both the electrical and the mechanical performance of the fitting.
Line & Substation Part Manufacturing Process
Line and substation hardware carries current and load outdoors for decades. We select the alloy for the duty, machine the clamp bodies and terminals to drawing, and gauge every termination thread before the part leaves.

Why Choose Machined Line & Substation Hardware
Overhead and substation fittings are replaced only during an outage, so the cost of a premature failure is measured in downtime rather than in the price of the part. Machined hardware gives you control of the contact geometry and the clamping range, which is where line fittings actually fail.
Conductivity-led material choice
Copper alloys and brass on current paths, aluminium on structure.
Outdoor service life
Grades and finishes selected for weather and galvanic exposure.
Material traceability
Test certificates with every batch, third-party NABL reports on request.
Full fitting range from one supplier
Clamps, terminals, links, brackets and small hardware.
Made to utility and OEM drawings
Made to utility and OEM drawings, including live-line tapping hardware.
Contact geometry machined
Contact geometry machined, not formed - consistent clamping area across the batch.
