Micro Coaxial Cable

In industries ranging from power transmission to telecommunications, coaxial cables are often exposed to high – voltage environments. A passed high – voltage resistance test is not just a routine certification; it is a critical guarantee that the cable can operate stably, safely, and durably under demanding conditions. For engineers, procurement teams, and end – users searching for this topic, understanding the value of this test result and its practical implications is key to making informed decisions about cable selection and system reliability.

Key Standards Guiding the High – Voltage Resistance Test

A “passed” test is only meaningful when measured against recognized international or industry standards. These standards define the test methods, voltage levels, and acceptance criteria, ensuring consistency and credibility across products.

IEC 60502: Developed by the International Electrotechnical Commission (IEC), this standard specifies high – voltage test requirements for power cables. For coaxial cables used in medium – to high – voltage power systems, it mandates tests like 10 – minute withstand voltage at 1.73 times the rated voltage to check for insulation integrity.
ANSI/ICEA S – 94 – 649: This American National Standard focuses on coaxial cables for communication and control applications. It requires tests such as a 60 – second high – voltage soak test at 3,000 V DC to verify that the cable’s insulation does not break down or leak excessive current.
UL 44: Underwriters Laboratories (UL) standard UL 44 covers insulation performance for wires and cables. It includes high – voltage dielectric tests to ensure coaxial cables meet safety thresholds for residential, commercial, and industrial use.

Core Indicators Evaluated in the Test

A passed high – voltage resistance test validates multiple critical performance indicators of the coaxial cable, each directly impacting its real – world performance.

Insulation Resistance: The test measures how well the cable’s insulation (e.g., PTFE, polyethylene) resists current leakage under high voltage. A passed result means leakage current is below the maximum limit (typically <10 μA), preventing energy loss and reducing fire risks.
Breakdown Voltage: This is the minimum voltage that causes the insulation to fail. A passed test confirms the cable’s breakdown voltage exceeds the rated operating voltage (often by 2–3 times), ensuring it can handle voltage spikes (e.g., from lightning or power surges) without failure.
Partial Discharge (PD): For high – voltage coaxial cables (e.g., those in 11kV+ power systems), the test checks for partial discharge—small electrical sparks within insulation gaps. A passed result means PD levels are below 10 pC, avoiding long – term insulation degradation that leads to cable failure.

Practical Value for End – Users and Systems

For those relying on coaxial cables, a passed high – voltage resistance test translates to tangible benefits that reduce operational risks and costs.

Enhanced System Reliability: In telecommunications towers, for example, coaxial cables carry high – frequency signals and may be exposed to induced high voltages. A passed test ensures the cable won’t fail unexpectedly, minimizing downtime for signal transmission.
Improved Safety: In industrial settings (e.g., manufacturing plants with high – voltage machinery), a failed coaxial cable could cause electric shocks or equipment damage. A passed test eliminates these hazards, protecting workers and assets.
Longer Service Life: Cables that pass high – voltage tests have intact insulation, which resists aging from voltage stress. This extends the cable’s lifespan by 30–50% compared to untested or failed cables, reducing replacement costs over time.
