KVVP2-450/750V
KVVP2 Copper Tape Screened PVC Control Cable — 450/750 V
Copper tape screen at 100 % coverage for fixed runs that must reject high-frequency interference.
KVVP2 replaces the braid of KVVP with a helically applied copper tape, normally 0.05 mm, laid with an overlap so the shield is continuous along the whole length. Coverage is effectively 100 %, which removes the apertures a woven braid always leaves and makes the screen markedly better against interference above about 1 MHz — fast switching transients, radio transmitters, and the harmonics that a poorly filtered drive throws back into the supply.
The trade-off is mechanical and electrical at low frequency. A 0.05 mm tape carries higher DC resistance than a braid, so its transfer impedance at power frequency is worse, and repeated bending work-hardens and tears it. KVVP2 is therefore a fixed-installation cable: racked, cleated or trunked, installed once and left alone. It also uses less copper, so it costs less than a comparable KVVP, which is why it is common on panel-internal wiring and on long runs where budgets are tight.

Engineering characteristics
- Continuous copper tape screen with no braid apertures, effective against interference above roughly 1 MHz
- Lower shield DC resistance path than foil-only constructions because the drain wire is bonded along the tape
- Lower copper content than an equivalent braid screen, which reduces both price and kg/km
- 450/750 V rating, 2.5 kV rms for 5 min including core to screen
- PVC/A insulation rated 70 °C continuous, 160 °C for 5 s short circuit
- Smaller overall diameter than KVVP at the same core count, so more cores fit one gland
- Supplied with ZR-KVVP2 and WDZ-KVVP2 sheath compounds on request
Typical applications
- Panel-internal wiring where RF fields or fast transients corrupt unshielded circuits
- Telemetry and SCADA cable runs inside control buildings and rack rooms
- Long fixed cable racks on water, wastewater and district heating schemes
- Signal wiring near radio transmitters, radar and induction heating equipment
- Replacement runs on existing installations where gland size is already fixed
Ordering options
- Composite foil plus braid screen where both low-frequency and RF performance are required
- ZR-KVVP2 flame-retardant and WDZ-KVVP2 low-smoke halogen-free sheath compounds
- KVVP2-22: steel tape armour for burial and exposed mechanical duty
- Aluminium foil plus tinned drain wire as a lower-cost screen alternative
- Numbered, DIN 47100 or customer-specified core identification

KVVP2 Copper Tape Screened Control Cable — frequently asked questions
Why is KVVP2 cheaper than KVVP at the same size?
A 0.05 mm tape uses far less copper than a woven braid of 0.12–0.20 mm wires, and it is applied in one pass rather than on a braiding machine. The saving is real but comes with less flexibility and a higher-resistance shield path at low frequency.
Can KVVP2 be used on a moving machine part?
No. Repeated bending work-hardens the tape and it cracks, opening the shield at the bend. For any moving application use a braid screen — KVVRP if the conductors also need to be Class 5 flexible, or a purpose-built drag chain cable.
Is 100 % coverage always better than 90 % braid coverage?
Not at every frequency. Coverage governs high-frequency leakage, so the tape wins there. At power frequency and at VFD carrier frequencies the deciding factor is the resistance of the shield path, and a braid wins that comparison. Match the screen to the interference spectrum.
How do I terminate the copper tape screen?
Fold the tape back over the sheath and clamp it with a metal screen clamp or an EMC gland so the contact is circumferential. Do not twist the drain wire into a pigtail — the added inductance defeats the screen above a few hundred kilohertz.
