PVC insulation compounds are essential materials used in power cables to ensure electrical safety, durability, and performance. These compounds are specially formulated to provide excellent insulation, flame resistance, and environmental protection.
11627 105℃ UL Standard PVC Electronic Wire Compound
Key Properties of PVC Insulation Compounds
High Dielectric Strength
Prevents electrical leakage and ensures safe power transmission.
Suitable for low to medium voltage applications (up to 35 kV).
Excellent Thermal Stability
Operates effectively in temperatures ranging from -20°C to 70°C.
Resists degradation under continuous load conditions.
Flame Retardancy
Many PVC compounds are formulated with additives to meet flame-retardant standards (e.g., UL94, IEC 60332).
Flexibility and Durability
Allows easy installation and resists cracking during bending.
Withstands mechanical stress and abrasion.
Chemical and Moisture Resistance
Protects cables from oils, acids, and humidity, making them ideal for harsh environments.
Comparison: PVC vs. Other Insulation Materials
| Property | PVC Insulation Compound | XLPE (Cross-Linked Polyethylene) | EPR (Ethylene Propylene Rubber) |
|---|---|---|---|
| Cost | Low | High | Very High |
| Max Voltage Rating | Up to 35 kV | Up to 500 kV | Up to 69 kV |
| Flame Resistance | Good (with additives) | Excellent | Moderate |
| Flexibility | High | Moderate | Very High |
| Operating Temp Range | -20°C to 70°C | -40°C to 90°C | -50°C to 150°C |
Note: PVC is the most cost-effective choice for general-purpose power cables, while XLPE and EPR are used in high-voltage or extreme-temperature applications.
Applications of PVC Insulation Compounds
Building Wiring Cables (Residential and commercial electrical systems)
Industrial Power Cables (Machinery, motors, and control systems)
Underground and Submarine Cables (Moisture-resistant formulations)
Renewable Energy Cables (Solar and wind power installations)
Automotive Wiring (Flexible and abrasion-resistant grades)
How to Choose the Right PVC Insulation Compound
When selecting a PVC compound for power cables, consider:
Voltage Requirements (Low, medium, or high voltage)
Environmental Conditions (UV exposure, moisture, chemicals)
Safety Standards (UL, IEC, RoHS compliance)
Flexibility Needs (Shore A hardness for installation ease)
