Instrument Cable Compound Industry Knowledge

Key performance requirements of instrument cable compound: How to balance signal transmission and mechanical protection?

Instrumentation Cable is widely used in industrial automation, process control, energy monitoring and other fields. Its core function is to stably transmit weak current signals (such as 4-20mA, RS485, Ethernet signals, etc.) while resisting mechanical stress, electromagnetic interference and environmental corrosion. Cable Compound, as an insulation and sheath material, directly affects the electrical performance, mechanical strength and service life of the cable.

Core contradiction:
Signal transmission requirements → low dielectric loss, high insulation, anti-interference.
Mechanical protection requirements → high wear resistance, bending resistance, tensile resistance, and impact resistance.

How to achieve a balance between the two through material formulation and structural design?

Key indicators of signal transmission performance

Low dielectric constant (Dk) and low dielectric loss (Df)
Impact: When high-frequency signals are transmitted, excessive Dk/Df will cause signal attenuation (such as Ethernet cables).

Material selection:
Insulation layer: PE (Dk≈2.3), foamed PE (Dk≈1.5), PP (Dk≈2.2).
Sheath layer: low polarity TPE or PVC (requires optimized formulation).

High insulation resistance and voltage resistance
Standard requirements: IEC 60502 stipulates that the insulation resistance is ≥10⁴ MΩ·km.

Key factors:
Material purity (avoid leakage current caused by impurities).
Additives (such as antistatic agents should be used with caution).

Electromagnetic shielding effectiveness
Application scenarios: Anti-EMI/RFI interference (such as near industrial field inverters).

Solution:
Shielding layer design: copper wire braiding, aluminum foil composite shielding.
Sheath material: conductive carbon black can be added (but flexibility may be sacrificed).

Key indicators of mechanical protection performance

Bending and fatigue resistance
Test standard: IEC 60228 (bending life test).
Material optimization:
Elastomer modification: TPU, POE, etc. improve resilience.
Structural design: twisted conductor + spiral shielding layer reduces stress concentration.

Wear resistance and anti-rollover
Industrial scenario requirements: such as drag chain cable (Chainflex), mining machinery cable.
Sheath material selection:
PUR (polyurethane): high wear resistance, but high cost.
CPE (chlorinated polyethylene): balance cost and performance.

Environmental adaptability
Oil/chemical corrosion resistance: petrochemical, shipbuilding and other scenarios need to pass ISO 6722 test.
Weather resistance: UV stabilizers (such as carbon black) prevent outdoor aging.

Solution for balancing signal and mechanical performance

Layered material design
Example structure:
Inner layer (insulation): foamed PE (low Dk/Df).
Outer layer (sheath): TPU or CPE (high mechanical strength).

Additive synergistic optimization
Nano fillers: such as SiO₂ to increase strength without affecting dielectric properties.
Plasticizer selection: avoid migration and reduce insulation performance.

Process control
Extrusion process: multi-layer co-extrusion to ensure interface bonding.
Cross-linking technology: Radiation cross-linked PE (XLPE) improves temperature resistance and mechanical strength.
