II. Core Information of the YVFB Flexible Flat Cable
(I) Product Definition
YVFB
Full name:
Copper-conductor PVC-insulated NBR-sheathed flexible flat cable
is specially designed for
high-frequency movement and bending scenarios
an industrial control cable featuring a space-saving flat structure, high flexibility and fatigue resistance, oil resistance and wear resistance, which can replace traditional round cables for power and signal transmission in compact equipment layouts.
(II) Application Scenarios
Typical Equipment
Functional Requirements
Automated production lines
Transplanters, stackers, AGV carts
Follow the equipment's reciprocating movement and transmit control signals
Logistics and warehousing
Conveyor belts, lifting platforms, shuttles
Adapt to multi-angle bending, resistant to dragging wear
Lifting machinery
Overhead traveling cranes, gantry cranes, electric hoists
Vertical suspended movement, bearing tension and torsion
Woodworking machinery
Sliding table saws, edge banding machines, engraving machines
Resistant to wood dust and oil corrosion, low-noise operation
Packaging machinery
Filling machines, sealing machines, labeling machines
High-frequency start-stop bending, resistant to mechanical vibration
(III) Core Features
Structural and Spatial Advantages
Flat design
Optimized width/thickness ratio (usually 2:1 to 3:1); compared with round cables of the same core count, it saves
40% of installation space
Suitable for narrow cable troughs or drag chains.
Low-stickiness surface
The sheath is treated with a matte process and is non-sticky during installation, improving wiring efficiency by
25%
High Flexibility and Fatigue Resistance
Bending performance
The minimum bending radius is only
8× the cable outer diameter
It can withstand≥1 million bending cycles(Test conditions: frequency 20 times/minute, bending angle 180°).
Anti-torsion design
The conductor adopts
pair twisting + layered cabling
technology, with low friction between cores, adapting to 360° rotation of equipment.
Environmental Adaptability
Temperature resistance range
-20°C to +80°C (optional high-temperature type -40°C to +105°C).
Oil and wear resistance
The NBR sheath resists mineral oil corrosion (weight change ≤2% after 72 h immersion), wear index ≤100 mg (DIN 53516).
Flame retardancy
Complies with IEC 60332-1; does not spread when exposed to open flame, suitable for crowded industrial scenarios.
Electrical Stability
Conductor material
Multi-strand oxygen-free copper wire (purity ≥99.99%) with precisely controlled stranding lay; DC resistance is 5% below the national standard, reducing heat loss.
Insulation performance
The PVC insulation layer has uniform thickness, insulation resistance ≥1000 MΩ·km, and withstands a 3000 V/5 min breakdown voltage test without abnormality.
