Polymerkablar

Polymerkablar are cables whose insulation and outer jacket are made primarily from polymer-based materials. The term is commonly used in various languages to describe electrical, signaling, and data transmission cables that rely on polymer compounds rather than metal shields or ceramic insulators. They are used across residential, commercial, and industrial settings, as well as in transportation and telecommunications applications.

Construction and materials

A typical polymerkablar comprises a conductive core of copper or aluminum, surrounded by polymer insulation. Common insulation polymers include polyvinyl chloride (PVC), polyethylene (PE), cross-linked polyethylene (XLPE), and fluoropolymers such as PTFE or FEP. The outer jacket is often another polymer, such as PVC, PE, fluorinated polymers, or low-smoke, zero-halogen (LSZH) formulations. Additives such as flame retardants, UV stabilizers, and moisture barriers may be included to meet performance requirements. Polymer formulations are engineered to balance electrical, mechanical, and thermal properties for specific applications.

Types and applications

Polymerkablar encompass a wide range of products, including power cables, control and instrumentation cables, data and communication cables, coaxial and certain fiber optic enclosures with polymer jackets. They are widely used in building wiring, industrial automation, automotive harnesses, consumer electronics, and outdoor or underground installations where flexibility, resistance to moisture, and ease of installation are advantageous.

Standards and performance

Manufacturers design polymerkablar to meet national and international standards concerning electrical safety, fire behavior, and durability. Relevant considerations include insulation resistance, conductor ampacity, flame propagation, smoke production, and environmental exposure. Standards bodies such as IEC and UL publish specifications for different cable types and use cases.

Environmental and safety considerations

Polymer-based insulation and jackets impact recyclability and environmental footprint. Developments emphasize halogen-free formulations, reduced smoke characteristics, and end-of-life recycling. Proper selection aligns performance with safety, sustainability, and regulatory requirements.
