Control Cable Compound Industry Knowledge

Performance requirements and selection guide for composite materials for control cables

1. Composite materials for control cables

Control cables are widely used in industrial automation, power systems, rail transit and other fields. Their core function is to transmit signals or low-power electrical energy. The outer sheath and insulation layer of the cable usually adopt polymer composite materials, such as PVC (polyvinyl chloride), XLPE (cross-linked polyethylene), TPE (thermoplastic elastomer), etc. Different application scenarios have different requirements for material performance.

2. Key performance requirements

Electrical performance
Insulation resistance: To prevent current leakage, it must comply with standards such as IEC 60227/60245.
Dielectric strength: The ability to withstand high voltage breakdown, especially suitable for high-voltage environments.

Mechanical properties
Tensile strength and wear resistance: Ensure that the cable is not easily damaged during installation and dragging.
Flexibility: Frequent bending scenarios (such as robots and drag chain cables) require highly elastic materials (such as TPU).

Environmental adaptability
Temperature range:
PVC: -20°C~70°C
XLPE: -40°C~90°C
-Silicone rubber: -60°C~200°C (high temperature occasions).
Oil/chemical corrosion resistance: petrochemical, mining and other scenes require special formulas (such as CR chloroprene rubber).

Flame retardant and safety performance
Flame retardant grade: UL94 V-0, IEC 60332-1 (single vertical burning) or IEC 60332-3 (bundled burning).
Low halogen smoke (LSZH): low toxic smoke is required during combustion in confined spaces such as subways and tunnels.

Long-term reliability
Anti-aging: UV stabilizers are used for outdoor cables (such as photovoltaic power stations).
Hydrolysis stability: avoid material degradation in humid environments.

3. Selection Guide

Choose materials according to application scenarios

Application Scenario Recommended Material Key Properties Applicable Standards
Industrial Automation (Robotics, Drag Chains) PVC / TPE / TPU High flexibility, abrasion resistance, bend endurance IEC 60228, UL 758
High-Temperature Environments (Steel Plants, Boilers) XLPE / Silicone Rubber Heat resistance (-40°C~200°C), oxidation resistance IEC 60502, UL 44
Rail Transit (Subways, High-Speed ​​Rail) Halogen-Free Flame Retardant (LSZH) Low smoke, non-toxic, flame retardant EN 45545-2, BS 6853
Marine Engineering (Ships, Offshore Platforms) Saltwater-Resistant TPU / CR Corrosion-proof, hydrolysis resistance, UV resistance IEC 60092, IEEE 45
Renewable Energy (Solar, Wind Power) Cross-Linked Polyolefin (XLPO) Weather resistance, UV protection IEC 62930, UL 4703
Petrochemical (Hazardous Areas) Fluoroelastomer (FKM) Oil/chemical resistance, flame retardant API RP 14F, IEC 60079

Cost and performance balance
Economical: PVC (general scenario, lowest cost).
High performance: XLPE or TPU (long life, harsh environment).

Certification and standards
International standards: UL (US), CE (EU), RoHS (environmental protection).
Industry standards: GB/T (China), EN (Europe), IEEE (electricity).

4. Common problems and solutions

Question 1: Cable sheath cracking?
→ Check the cold resistance of the material (such as switching to XLPE) or whether the installation bending radius is too small.

Question 2: Severe signal interference?
→ Choose a composite structure with a shielding layer (such as aluminum foil + tinned copper wire).
