- Solid Rigid Copper Conductors:High-purity solid copper delivers stable low-resistance transmission for control signals and micro auxiliary power, with clear color marking on each core to speed up field wiring and later fault inspection. The 14-core integrated design consolidates multiple independent control loops into one cable.
- PVC Core Insulation Layer:PVC material provides reliable electrical isolation between adjacent cores, avoiding short circuit and signal crosstalk under 450/750V rated operating voltage, with stable heat aging resistance for long-term indoor & underground operation.
- Fillers & Wrapping Tape:Elastic fillers round out the cable structure and buffer extrusion from soil and pipeline during buried laying; wrapping tape fixes internal cores to prevent dislocation deformation.
- Copper Braided Overall Shielding Layer:Dense copper mesh fully shields electromagnetic noise generated by transformers, inverters and high-voltage equipment, eliminating control signal distortion and equipment misoperation in strong interference workshops and substations.
- PVC Inner Bedding Sheath：Isolates the copper shielding layer and metal steel tape armor, preventing friction scratch damage to the shielding layer and avoiding electrochemical corrosion between different metal layers.
- Double Galvanized Steel Tape Armor Layer:The core mechanical protection structure, resisting underground rock extrusion, construction impact, rat and termite gnawing damage, meeting national direct burial laying standards without additional heavy steel conduit protection.
- PVC Outer Sheath:Thickened anti-corrosion PVC outer layer isolates internal structure from underground moisture, weak acid & alkali soil and dust, preventing steel tape armor rust and extending service life in buried environments.
Key Advantages
- Multi-Layer Composite Protection: Copper anti-interference shield + steel tape mechanical armor dual protection, solving both electromagnetic interference and underground mechanical damage risks.
- Direct Underground Burial Available: Standard double steel tape armor structure supports direct burial in soil, greatly reducing pipeline engineering material and labor costs.
- 14-Core Integrated Layout: Centralizes multi-channel control circuits to tidy cable trench layout and save construction space.
- Wide Environmental Adaptability: Resists moisture, weak chemical corrosion, rat bite and extrusion, suitable for cable trench, underground direct burial and indoor fixed laying scenarios.
- Long-Term Anti-Aging Performance: PVC insulation & outer sheath formula resists thermal aging and soil erosion for decades of stable operation.
- Full Standard Compliance: Strictly produced in accordance with GB/T 9330 national standard for armored shielded control cables.

FAQ
Q1: What does KVVP22 stand for?
A: K = control cable; V = PVC core insulation; V = PVC inner bedding; P = copper wire braided overall shield; 22 = double galvanized steel tape armor + PVC outer sheath.
Q2: What is the difference between KVVP and KVVP22 cables?
A: KVVP has no steel tape armor, only suitable for indoor cable tray laying without mechanical impact risk; KVVP22 adds double steel tape armor, supporting underground direct burial and resisting extrusion, rat bite and impact damage.
Q3: Can KVVP22 be buried directly in soil without conduit?
A: Yes, its standard steel tape armor structure complies with national direct burial construction specifications; customized heavy anti-corrosion sheath is required for strong acid/alkali industrial soil environments.
Q4: What is the rated voltage of this control cable?
A: Rated voltage 450/750V, only applicable to low-voltage weak control signal and micro auxiliary power circuits, cannot be used for heavy-load main power transmission.
Q5: Do you supply flame retardant and fire-resistant KVVP22 cables?
A: Full series of modified products are available, including ZC-KVVP22 flame retardant, NH-KVVP22 fire-resistant, WDZN-KVVP22 low smoke zero halogen for public infrastructure fire safety projects.
QQ6: Will the steel tape armor rust underground?
A: The inner PVC bedding and sealed outer sheath isolate the steel tape from soil moisture; conventional neutral soil will not cause rust, special anti-corrosion outer sheath is matched for corrosive ground conditions.
