APPLICATION

 

Control cables transmit control and measuring signals rather than heavy power. They are widely used in power stations, substations, industrial automation, fire protection, buildings, new energy and municipal projects. Various types with shielding, fire resistance, flexibility and armor are available to fit indoor, outdoor, buried and harsh industrial installation environments.

• Conductor: Conductor: Copper, class 1, 2, or 5, solid，stranded round or soft conductor
• Insulation: Polyvinyl chloride PVC
• Filler: Non-hygroscopic material
• Binder: Non-hygroscopic material
• Metal shield: copper tape
• Outer sheath: Polyvinyl chloride PVC

• Rated Voltage:300/500V, 450/750V, 0.6/1kV

CHARACTERISTICS

Characteristics of PVC Insulated Copper Tape Shielded Control Cables

1. Core Structure Composition

  • Conductor: Bare copper conductor
  • Insulation layer: PVC polyvinyl chloride insulation
  • Shield layer: Wrapped copper tape shielding (distinct from copper wire braided shielding)
  • Inner liner & outer sheath: PVC sheath
  • Main model: KVVP2, KVVP2/22 (steel tape armored type)

2. Advantages

(1) Excellent electromagnetic interference suppression performance

Copper tape forms a continuous closed shielding layer with 100% coverage rate, far higher than braided shield (80%-90% coverage). It effectively blocks high-frequency electromagnetic interference from inverters, high-power motors, power cabinets, and avoids signal distortion, data loss or control malfunction of PLC, sensors and instruments. It performs better against radio frequency and high-frequency interference.

(2) Uniform shielding effect around the cable circumference

Thin copper tape is tightly lapped wrapped, forming a complete conductive cylinder. No shielding blind spots exist on the cable surface, while braided shield has gaps between woven copper wires which weaken shielding effect locally.

(3) Stable grounding conduction & good fault leakage capacity

The continuous copper tape layer provides a complete grounding path. When insulation breakdown occurs, leakage current can be quickly conducted to the ground for rapid circuit protection triggering, improving circuit safety.

(4) Cost advantage vs dense braided shield cables

Compared with thick high-coverage copper wire braided control cables, copper tape shielding consumes less copper raw material, reducing overall cable cost while maintaining superior high-frequency shielding performance.

(5) Basic performance inherited from PVC insulation

  1. Flexible PVC insulation and sheath, easy bending and cabinet wiring;
  2. Resistant to dilute acid, alkali and light oil, suitable for general industrial damp cable trenches;
  3. Complete multi-core specifications from 2 cores to 61 cores for multi-loop centralized control;
  4. Optional flame retardant type (ZR-KVVP2) to slow flame spread in fire.

(6) Compact cable outer diameter

The thin lapped copper tape takes up less radial space than thick braided copper mesh, resulting in smaller overall cable diameter, saving tray laying space and lowering engineering layout difficulty.

3. Disadvantages

(1) Poor mechanical tensile resistance of the shielding layer

Copper tape is thin and prone to cracking or breaking under excessive stretching, sharp bending or violent dragging during construction. Once broken, the shielding continuity is destroyed and anti-interference ability drops sharply. Copper wire braided shield has better tensile resistance for complex laying routes.

(2) Weak low-frequency interference shielding capacity

Copper tape shielding excels at high-frequency interference, but its shielding effect on low-frequency magnetic field interference (such as nearby large transformers) is inferior to copper braided shielding.

(3) Inherent defects of PVC material

  1. Long-term allowable working temperature only 70℃, not applicable to high-temperature workshop environments;
  2. Poor UV resistance, cannot be laid exposed outdoors without pipe protection;
  3. Releases toxic hydrogen chloride corrosive smoke when burning, not allowed for halogen-free public buildings;
  4. Easy to harden and crack under long-term low temperature below -15℃.

(4) Limited anti-extrusion without armor

Non-armored KVVP2 cannot bear heavy external pressure or rodent bite; KVVP2/22 with steel tape armor must be selected for direct underground burial.

4. Common Model Classification & Additional Functions

  1. KVVP2: PVC insulated copper tape shielded control cable, for indoor fixed laying with high-frequency interference sources;
  2. KVVP2/22: Copper tape shield + double steel tape armor, pressure-resistant, anti-rodent, available for direct underground burial or heavy-load cable trenches;
  3. ZR-KVVP2 / ZR-KVVP2/22: Flame retardant grade, used for fire control rooms, high-rise building automatic control systems.

5. Suitable & Unsuitable Application Scenarios

Suitable Scenarios

  • Automation workshops with numerous inverters, servo motors and high-frequency equipment;
  • Precision instrument, sensor and DCS signal transmission circuits requiring stable signal;
  • Indoor cable trays, control rooms, covered cable trenches with strong high-frequency electromagnetic radiation;
  • Medium-budget engineering projects that demand superior high-frequency shielding without excessive cost.

Unsuitable Scenarios

  • Construction routes with frequent stretching, sharp repeated bending or heavy dragging;
  • Environments dominated by low-frequency magnetic field interference near large transformers;
  • Long-term high-temperature power distribution rooms, unprotected open-air outdoor laying;
  • Hospitals, subways, data centers and other places requiring halogen-free low-smoke cables;
  • Frigid northern open-air laying without anti-freezing conduit.
