Product Introduction
This 37-core flexible control cable (KVVR 37×1.0mm²) is rated at 450/750V, specially designed for multi-loop control signal transmission in large electrical control cabinets and industrial automation systems. It adopts multi-strand flexible copper conductors, numbered yellow PVC core insulation, elastic round fillers and integrated PVC outer sheath. The high-core integrated design consolidates dozens of independent control circuits into one single cable, ideal for indoor fixed wiring with frequent bending requirements inside switchgear, DCS cabinets and building central control equipment.
product key technologies
-
Stranded flexible copper conductors (37 cores × 1.0mm²)
-
Number-marked yellow PVC insulation for each single core
-
Elastic filling materials & binding wrapping tape
-
Black PVC integrated outer protective sheath
- Stranded Flexible Copper Conductors:Multi-strand soft copper delivers stable low-resistance transmission for weak control signals and micro-auxiliary power. The flexible structure withstands repeated bending inside narrow cabinet channels without wire breakage. Every core is printed with unique digital serial numbers for rapid circuit identification and post-fault maintenance.
- PVC Core Insulation Layer:PVC insulation provides reliable electrical isolation between adjacent cores, preventing short-circuit and signal crosstalk under 450/750V rated operating voltage. It maintains softness under long-term bending without cracking or aging.
- Fillers & Wrapping Tape:Elastic fillers keep the cable round and compact, buffer internal friction during bending and avoid core dislocation; wrapping tape locks internal core layout to prevent loose deformation after long-term use.
- PVC Outer Sheath:Thickened PVC outer layer fully isolates internal cores from indoor dust, minor abrasion and ambient moisture, extending service life under dry indoor laying conditions.
Key Advantages
-
High-Core Integrated Design: 37 independent control loops in one cable drastically reduce wiring quantity, save cabinet internal space and cut construction labor & material costs.
-
Superior Bend Flexibility: Soft multi-strand copper adapts to narrow cabinet wiring channels and frequent bending layout, solving the hard wire breakage issue of rigid KVV cables.
-
Digital Number Marked Cores: Uniform yellow insulation with clear serial numbers simplifies circuit sorting, inspection and fault troubleshooting.
-
Stable Electrical Performance: Standard PVC insulation meets 450/750V withstand voltage requirement, no signal leakage or interference between multi-channel loops.
-
Cost-Effective General Control Solution: Balanced performance and raw material cost, the mainstream choice for large multi-loop control projects.
-
Indoor Environmental Durability: Resists dust, indoor humidity and light mechanical abrasion for decades of fixed indoor operation.

FAQ
Q1: What does KVVR stand for
A: KV = PVC insulated control cable; V = PVC outer sheath; R = multi-strand flexible copper conductor.
Q2: What is the difference between KVVR and rigid KVV control cable
A: KVV uses solid single rigid copper core, only suitable for straight fixed laying without frequent bending; KVVR adopts multi-strand soft copper, designed for cabinet wiring requiring repeated bending and threading.
Q3: Can this cable be laid outdoors exposed to sunlight and rain?
A: Standard PVC sheath is only suitable for indoor use; customized UV anti-aging outer sheath version is required for open-air outdoor laying.
Q4: Is 37-core KVVR applicable for large automation control cabinets?
A: Yes, the high-core integration greatly reduces scattered single wires inside cabinets, realizes neat and standardized wiring layout.
Q5: What is the rated voltage of KVVR control cable?
A: Rated voltage 450/750V, exclusively for low-voltage control signals and micro-power auxiliary circuits, not for heavy-load main power transmission.
Q6: Do you supply flame retardant and low smoke zero halogen KVVR cables?
A: We provide complete ZA/ZB/ZC flame retardant series and WDZ low smoke zero halogen KVVR cables for subway, hospital, school and high-rise building fire safety projects.
