2. Core Information of YVFB Flexible Flat Cable
(1) Product Definition
YVFB stands for Copper Core PVC Insulated Nitrile Sheathed Flexible Flat Cable. It is an industrial control cable specially designed for high-frequency movement and curved scenarios. It features a flat structure that saves space, high flexibility with fatigue resistance, oil resistance, and wear resistance. It can replace traditional circular cables for power and signal transmission in compact equipment layouts.

(3) Core Characteristics
1. Structural and Spatial Advantages
Flat Design: Width/thickness ratio optimized (usually 2:1 to 3:1), saving 40% installation space compared to round cables with the same number of cores, suitable for narrow cable ducts or drag chains.
Low-viscosity surface: The sheath is treated with a matte process, preventing sticking during installation and increasing wiring efficiency by 25%.
2. High flexibility and fatigue resistance
Bending Performance: The minimum bending radius is only 8× the outer diameter of the cable, and it can withstand **≥1 million bending cycles** (test conditions: frequency 20 times/minute, bending angle 180°).
Torsion-resistant design: The conductor uses twisted pairs and a layered cabling process, resulting in low friction between the cores, suitable for equipment 360° rotation conditions.
3. Environmental Adaptability
Temperature resistance range: -20°C~80°C (optional -40°C~105°C high-temperature resistant model).
Oil-resistant and wear-resistant: Nitrile jacket (NBR) resists corrosion from mineral oil (weight change ≤2% after 72 hours of immersion) and has a wear index ≤100mg (DIN 53516).
Flame retardant features: Complies with IEC 60332-1 standard, does not spread when exposed to open flames, suitable for densely populated industrial environments.
4. Electrical stability
Conductor material: multi-strand oxygen-free copper wire (purity ≥99.99%), precisely controlled twisting pitch, DC resistance below 5% of national standard, reducing heat loss.
Insulation performance: PVC insulation layer is uniformly thick, insulation resistance ≥1000MΩ·km, breakdown voltage 3000V/5min, no abnormalities.

3. Product Advantages
(1) Source factories, controllable costs
Price advantage: 10%-15% lower than similar products on the market; large quantities offer tiered discounts.
Fast delivery: Regular models are well-stocked and will be shipped within 48 hours after ordering, while custom products can be delivered in as fast as 7 working days.
(2) Customized Solutions
Function Expansion: ▶ Shielded Type (YVFB-P): Aluminum foil and copper braided double shielding, interference resistance increased to 95dB. ▶ Low Temperature Resistant Type (YVFB-D): Flexible without deformation at -40°C, suitable for cold storage and outdoor equipment in northern regions. ▶ High Flexibility Type (YVFB-G): Bending radius as low as 6× outer diameter, compatible with high-speed precision machinery.
Label Customization: The jacket can print customer logos, continuous meter marks, or warning messages (e.g., "High Voltage Danger").
(3) Quality Control System
Triple Inspection Process:
Raw Material Inspection: Copper wire conductivity test (≥58MS/m), comparison of jacket performance before and after aging (70°C × 168h).
Process Inspection: Online monitoring of insulation thickness, conductor DC resistance, cable uniformity.
Finished product testing:
Bending Fatigue Test (simulating 10-year usage cycle)
Oil Resistance Test (no swelling after 7 days immersion in motor oil)
Low Temperature Winding Test (no cracking when wound on a rod at -30°C)
4. Installation and Maintenance Recommendations
(1) Installation Precautions
Wiring Method:
Fixed installation: Can be directly laid in cable trays or trenches, with 5% length reserve left to prevent thermal expansion and contraction.
Mobile installation: It is recommended to use with a drag chain, leaving 10% extra cable length inside the drag chain to avoid excessive tension.
Bending radius: Strictly follow the minimum bending radius requirement; forced bending or sharp twisting is prohibited.
Fixed spacing: When installing hanging, set a fixed point every 500mm to reduce sagging stress.
(2) Maintenance
Regular inspections: Check the cable surface monthly for wear and cracks, and check for jamming inside the drag chain.
Cleaning and maintenance: Wipe the surface of the sheath with a dry cloth to remove oil and dust, avoiding direct contact with chemical solvents.
Status Record: Establish a cable usage file, recording the installation date, operating duration, and test results, to facilitate predicting replacement cycles.
