PLHV1-F Cable: High Voltage Test Lead Wire for Industrial Diagnostics and Factory HV Testing
High voltage tests fail when the weakest link isn’t the DUT—it’s the lead wire. A stiff, under-shielded cable that breaks down under partial discharge or tangles across a factory floor turns a routine withstand test into a margin-of-error gamble. That risk is unnecessary. The PLHV1-F cable replaces guesswork with controlled electrical clearance, uniform field grading, and silicone insulation that stays flexible from -60°C to +180°C. For QA managers running repetitive hipot sequences or field engineers verifying switchgear in harsh climates, this lead wire removes one variable that should never be a variable: the test lead itself.
Fewer re-tests, fewer false breakdowns, cleaner data. This is how you reduce production bottlenecks tied to poor test rig cabling—without overpaying for exotic dielectrics. Every PLHV1-F assembly is built to your specified length, termination type, and voltage class. That means you match the exact connection geometry of your test bench or mobile diagnostic kit on day one.
Flexible dielectrics that withstand corona and mechanical stress
Double-layer silicone compound, controlled semicon underlayer
The conductor shield and outer insulation work together to suppress corona below < 5 pC at rated working voltage.
This gives you clean partial discharge readings even when the cable must route past grounded metal enclosures. False fails drop. Retest loops shrink.
Stranded tin-plated copper, ultra-fine wire count
High strand count (typ. 0.08–0.10 mm individual wires) shifts bending fatigue away from the copper, not the insulation.
You can coil the cable tightly, pull it through conduit, or drag it across a concrete production bay. It will not work-harden and snap internally behind the jacket.
Custom termination from a single engineering desk
We don’t hand you a catalog and ask you to compromise. Specify 4 mm safety banana, heavy-duty crocodile clamp, M6 ring lug, or SHV/MHV coaxial shell. Cable exit angles, strain relief moulding, and jacket colour (red, black, white, blue, yellow) are all configurable.
Your test operator plugs in a lead that matches the equipment layout—no tape-wrapped adapters, no clip leads stretched to failure.
Factory-tested at 1.5× rated DC voltage before dispatch
Every finished assembly undergoes a go/no-go hipot and PD screening tied to your order spec. The test report ships with the cable.
You receive a traceable record instead of a generic promise. ISO 9001 audit trails become straightforward.

Where PLHV1-F eliminates recurring cable problems
- Transformer and switchgear factory routine testing – Repeated hipot cycles on the same station degrade ordinary PVC leads within weeks. Silicone insulation and reinforced terminations survive heat, oil mist, and hourly reconnection.
- Power utility field diagnostics (Megger / VLF testing) – Field crews work from truck trays in rain or frost. Cables that stay pliable at -30°C coil fast and don’t introduce leakage current that masks insulation resistance readings.
- Cable manufacturer partial discharge labs – Background noise from a poorly designed test lead can exceed 50 pC. PLHV1-F keeps base PD quiet so you measure the cable sample, not the setup.
- Hipot and dielectric withstand stations in EMS/PCB factories – Short, custom-length leads with right-angle connectors reach densely packed safety test jigs without stressing the port or blocking the operator’s line of sight.
- Aerospace & EV component high-pot testing – Compact, high-temperature-tolerant leads handle bench testing of stator windings, busbars, and connectors where ambient heat from UUTs pushes PVC past its limit.
