Control Cable — KVV, KVVP, LSZH and screened variants
Multicore control and signalling cable for switchgear, automation panels and fixed industrial routes. Choose by screening requirement first, then by armour and sheath — the core construction is shared across the family.
§01 — Range
Control cable types — unscreened, screened, flexible and LSZH
PVC Control Cable, Unscreened (KVV / KVV22)
Unscreened control cable, with steel-tape armour (KVV22) for direct-buried or mechanically exposed control runs.
Screened Control Cable (KVVP / KVVP2)
Copper-braid or copper-tape screened cable for EMI-sensitive control and measurement loops.
LSZH Control Cable (WDZC-KYJY)
Low-smoke halogen-free flame-retardant control cable — measured values from report 202521001018 published on the page.
Flexible Control Cable (KVVR / KVVRP)
Flexible class 5 conductors for moving machine connections and cabinet wiring.
Instrumentation and Computer Cable
Pair-twisted, individually and collectively screened cable for DCS and instrumentation loops.
Flame-Retardant Control Cable (ZR-KVV)
Flame-retardant control cable where IEC 60332-3 bunched performance is specified.
Why our LSZH page is different
Most factories write “strict quality control”. We publish the measured values: smoke transmittance 80 % (requirement ≥ 60 %), bunched flame class C char height 0.6 m (limit 2.5 m), conductor resistance 11.5 Ω/km (limit 12.1), 3000 V / 5 min no breakdown.
§02 — Selection
Specifying a control cable: the three decisions
| Question | Answer drives |
|---|---|
| Is the loop near power cables or drives? | Yes → screened KVVP / KVVP2; no → KVV is sufficient |
| Is the run buried or mechanically exposed? | Yes → armoured KVV22; no → unarmoured |
| Are smoke and halogen regulated (tunnel, metro, hospital)? | Yes → WDZC-KYJY LSZH with the published type test |
