LAPP, the Stuttgart-based cable and connector manufacturer, has developed a condition-based monitoring (CBM) capability aimed at power and control cables, shifting maintenance strategy from fixed replacement intervals toward measurement-driven decisions on industrial cable assets.

The company disclosed the development through its news channel but, at the time of writing, has not published the underlying measurement specifications — no sensor types, accuracy figures, sampling rates, or communication interfaces appear in the announcement itself. This is a strategy announcement, not a datasheet release, and buyers should treat performance claims accordingly until LAPP documents test conditions.

Why does condition-based monitoring matter for cables?

Power and control cables in factories, energy infrastructure, and rolling stock typically degrade through insulation aging, mechanical wear from cable-chain movement, thermal cycling, and moisture ingress. The traditional answer is preventive replacement: swap the cable at a conservative interval regardless of its actual state. That interval must cover worst-case aging, so it discards service life.

Condition-based monitoring instead measures proxies for cable health — insulation resistance, partial-discharge activity, capacitance changes, temperature, or mechanical strain — and triggers intervention only when a measured threshold indicates degradation. The physics argument is straightforward: insulation breakdown is progressive and observable before failure, so a monitoring system converts an unplanned outage risk into a scheduled maintenance action.

For control cables in particular, intermittent faults from conductor breakage or insulation damage are among the hardest failure modes to diagnose on a running line. Continuous or periodic measurement narrows fault localization time.

What is LAPP actually offering?

The announcement confirms the direction — LAPP is building monitoring for its own cable portfolio — but leaves open the architecture questions that determine cost of ownership:

• Sensing method: electrical diagnostics on the installed cable, add-on sensors along the route, or instrumented connectors at the terminations.
• Retrofit scope: whether the system applies to existing installed cable plants or only to new LAPP-specified assemblies.
• Data path: local indication, PLC integration, or cloud analytics with alarm thresholds.
• Diagnostic coverage: whether the system distinguishes insulation aging from conductor fatigue, which require different remedies.

LAPP has a commercial rationale for entering this layer. As the cable manufacturer, it holds the construction data — conductor geometry, insulation material, rated voltage — that a third-party monitoring vendor must estimate. That data underpins any aging model that converts raw measurements into remaining-useful-life estimates.

How should buyers evaluate it?

Cable condition monitoring competes on false-alarm rate and detection lead time, not on the presence of a sensor. When LAPP publishes specifications, procurement teams should ask for:

• detection thresholds stated against a defined failure criterion (e.g., insulation resistance floor per IEC 60227/60502 class);
• validation data from aged-cable tests, not accelerated-aging extrapolation alone;
• the minimum fault size detectable at a stated cable run length;
• behavior in electrically noisy environments — VFD-driven lines in particular.

The adoption question

If LAPP couples monitoring to its cable business, the open question is whether industrial operators will accept health data tied to a single manufacturer's product line, or whether an open, cable-agnostic diagnostic standard — analogous to what vibration ISO standards did for rotating machinery — will be required before CBM becomes procurement default rather than a vendor option.
