TEST LEADS
Instrument test leads
State the instrument, measurement circuit, lead length and required conductor size. Include the complete probe and connector specification.
Typical application
APPLICATION / Test & instrumentation
Silicone Wire for
Test Equipment
From the instrument to the test point.
For test leads and instrument wiring, we start from flexible silicone single-core wire: 0.08 mm tinned-copper strands with silicone rubber insulation, 28 AWG to 2 AWG, rated −60 °C (−76°F) to +180 °C (356°F) continuous and +200 °C (392°F) short-term.
AT A GLANCE
Test lead wiring at a glance
Each test connection and the silicone wire we start from.
| Connection | Cable construction | Key point |
|---|---|---|
| Instrument test leads | Flexible silicone single-core wire | 0.08 mm fine-stranded tinned-copper conductor |
| Bench and fixture wiring | Flexible silicone single-core wire, 28 AWG to 2 AWG | Checked against your fixture and test method |
| Instrument internal connections | Flexible silicone single-core wire | Shielding specified separately |
CONNECTION TASKS
Test equipment wiring
Our flexible silicone single-core wire is used for instrument test leads. The rating of a finished probe or test-lead set depends on the complete assembly.
TEST FIXTURES
Bench and fixture wiring
Wire for test fixtures and bench connections. Conductor size and terminations follow the measurement circuit.
Checked for your fixture
INTERNAL WIRING
Instrument internal connections
Mark internal power or signal connections on the instrument drawing. Identify shielding or specialised signal requirements separately.
Selected for your circuit
SELECTION CHECKS
Operating conditions to specify
Include these conditions with your enquiry so we can select the right cable.
Measurement duty
Operating voltage, current, test method and any measurement-category documentation define the lead.
Lead handling
Routing, bend locations, manual handling or repeated motion and the test conditions set the mechanical duty.
Complete connection
Probe, connector, strain relief and termination requirements matter as much as the wire insulation.

BEFORE YOU SPECIFY
Frequently asked questions
Are these finished CAT-rated test leads?
This page offers wire, not a finished CAT-rated probe or test-lead set. Any measurement-category rating applies to the complete assembly.
Does silicone insulation establish coaxial or precision-signal performance?
No. Coaxial geometry, impedance, screening and measurement requirements need a separate specification.
Which wire sizes are listed for test leads?
28 AWG to 2 AWG, with outside diameters from 1.2 mm to 12.5 mm. The conductor is made of 0.08 mm tinned-copper strands.
