§01 — Product family

Four constructions, one system voltage.

Technical data — reference only. Figures in the tables below are reference values for early-stage project comparison. Conductor size, insulation and sheath thickness, overall diameter, DC resistance and ampacity are confirmed against the approved cable schedule and the applicable standard (GB/T 9330 / IEC 60245) before production. Ampacity is quoted for installation in free air at 40 °C ambient; ratings for buried, in-conduit or tray installation differ. Dimensional and electrical tolerances follow the relevant standard. LSZH (WDZC-KYJY) variants in this family are verified by third-party test report No. 202521001018 to GB/T 9330-2020.

Тип	Экран / броня	Use
KVV	None	Control circuits inside panels, trays and dry indoor routes
KVVP	Copper-braid screen	EMI-sensitive control and measurement loops near drives and power cables
KVVP2	Copper-tape screen	Higher screening coverage for instrument-grade loops
KVV22	Steel-tape armour	Direct burial and mechanically exposed control runs

КОНСТРУКЦИЯ

What is inside

Copper class 1 (or class 5 flexible) conductors → PVC insulation with numbered cores → optional copper braid or tape screen → PVC outer sheath. Flame-retardant (ZR-KVV) and LSZH (WDZC-KYJY) variants share the same core.

For LSZH control cable with published type test, see the WDZC-KYJY LSZH control cable page.

§03 — FAQ

Common questions on control cable.

When do we need KVVP instead of KVV?

Whenever the control loop runs parallel to power cables or near VFDs and soft starters: the copper-braid screen keeps induced noise out of measurement and interlocking signals. As a rule, analogue signals and safety interlocks get screened cable; simple 24 V DC switching in clean panels can stay unscreened.

Control cable vs power cable — what is the actual difference?

Voltage class and duty, not size. Control cable is 450/750 V with many small cores for signalling and interlocking; power cable is 0.6/1 kV and above with few large cores for energy transfer. Running control signals on power cable (or vice versa) fails both inspection and EMC practice.

Do you have an LSZH control cable with a test report?

Yes — WDZC-KYJY 450/750 V passed a complete third-party type test (report No. 202521001018, GB/T 9330-2020): smoke transmittance 80 %, bunched flame class C, halogen-free. The measured values are published on the LSZH control cable page.

Can cores be numbered and colour-coded to our wiring diagram?

Numbered black cores are standard. Colour-coded cores and printing of the buyer’s circuit references on the sheath are available for project orders — include the wiring schedule with the RFQ.
