Electrical Performance Indicators
Dielectric Strength
Dielectric strength refers to the maximum electric field that a material can withstand without experiencing electrical breakdown. This property is critical for communication cables, as it ensures the insulation remains intact under high voltage stress, preventing signal loss or short circuits. In modern high-speed networks, where data transmission rates are extremely high, even minor insulation failures can cause significant communication errors.
When comparing materials, High-performance cable compounds for telecom applications like XLPE typically exhibit superior dielectric strength compared to traditional PVC, making them more suitable for long-distance or high-frequency signal transmission. Eco-friendly compounds for communication cables also focus on maintaining high dielectric strength while reducing environmental impact.
Comparison:
| Material Type | Dielectric Strength (kV/mm) | Remarks |
| PVC | 12–14 | Common in low-cost cables, moderate performance |
| XLPE | 18–22 | High-performance, ideal for telecom and data cables |
| EPR | 15–18 | Good flexibility, medium-high dielectric strength |
Volume Resistivity
Volume resistivity measures a material's resistance to electric current flow through its bulk. High resistivity reduces leakage currents, minimizes energy loss, and maintains signal integrity over long distances. For B2B clients, selecting compounds with high volume resistivity ensures reliability and compliance with stringent telecom standards.
Comparatively, Flame retardant cable compounds for data cables maintain high resistivity even under elevated temperatures, while Flexible cable compounds for high-speed networks balance resistivity with mechanical flexibility to withstand bending and installation stresses. Volume resistivity is also a key metric when evaluating outdoor cables exposed to moisture or varying temperatures.
Comparison:
| Material Type | Volume Resistivity (Ω·cm) | Remarks |
| PVC | ≥1×10¹³ | Standard insulation, adequate for indoor cables |
| XLPE | ≥1×10¹⁴ | Excellent for high-frequency and long-distance applications |
| EPR | ≥1×10¹³ | Good resistivity with enhanced flexibility |
Mechanical Performance Indicators
Tensile Strength
Tensile strength quantifies the maximum stress a material can endure while being stretched before it breaks. This metric is critical for cables that must endure installation tension, pulling, or environmental stress. In industrial applications, using compounds with insufficient tensile strength can result in premature cable failure, downtime, and increased maintenance costs.
High-performance solutions, such as High-performance cable compounds for telecom applications, often combine high tensile strength with flexibility to ensure both durability and ease of installation. In contrast, standard PVC compounds may suffice for indoor wiring but are less reliable for high-stress or outdoor environments.
Comparison:
| Material Type | Tensile Strength (MPa) | Remarks |
| PVC | 15–20 | Suitable for low-stress indoor cables |
| XLPE | 18–22 | Optimal for telecom, data, and high-speed networks |
| EPR | 8–12 | Flexible but lower tensile strength |
Elongation at Break
Elongation at break measures the extent a material can stretch before failure. A higher value indicates better flexibility, which is particularly important for cables in environments with frequent bending, vibration, or movement. Compounds designed for outdoor or high-speed network applications often prioritize higher elongation to avoid cracking and ensure long-term reliability.
UV-resistant cable compounds for outdoor installations often pair high elongation with UV stability, ensuring cables remain durable under sun exposure. Similarly, flexible compounds for high-speed networks combine elasticity with high tensile and dielectric performance, balancing mechanical and electrical requirements for modern data infrastructures.
Comparison:
| Material Type | Elongation at Break (%) | Remarks |
| PVC | 150–200 | Moderate flexibility, suitable for indoor cables |
| XLPE | 300–500 | High flexibility, ideal for telecom and data cables |
| EPR | 250–400 | Balanced flexibility with moderate tensile strength |
