Lyginamoji analizė: PVC ir kryžminio ryšio polietilenas automobilių laiduose

Choosing the right insulation material for automotive wiring is crucial to performance, kaina, and safety. Two of the most common materials¡ªPVC and Cross-Linked Polyethylene (Xlpe)¡ªeach offer unique benefits and trade-offs. This article compares their properties across key selection criteria.
Mechanical Characteristics

PVC: Excellent flexibility and ease of processing; suitable for confined spaces.

Xlpe: Higher mechanical strength and abrasion resistance; better for high-demand zones.

Electrical Properties

PVC: Good dielectric strength, suitable for low to medium voltage.

Xlpe: Superior dielectric properties and lower capacitance; better for high-voltage EV applications.

Environmental Resistance

PVC: Prone to degradation under UV and high temperatures.

Xlpe: Resistant to ozone, UV, and thermal aging.

Regulatory Compliance

PVC: Meets general automotive wiring standards.

Xlpe: Often preferred for meeting ISO 6722 Class D or higher.

Use Case Scenarios

PVC: Dashboards, infotainment wiring, interior applications

Xlpe: Engine compartments, battery lines, and high-voltage EV routes

Išvada

PVC and XLPE each serve specific automotive needs. The choice depends on the application environment, performance demands, and regulatory requirements. Understanding these differences helps manufacturers optimize design and cost.
