Flame Retardant Cross-Linked Polyethylene (FR-XLPE) serves as the insulation material for this electrical cable, providing both high thermal tolerance and fire-resistant performance.

FR stands for Flame Retardant, meaning the wire resists propagating flames along its length. XLPE, or Cross-Linked Polyethylene, is a durable polymer sheath that withstands significantly higher temperatures than standard insulation materials.

Application

These cables are frequently deployed in power distribution, control systems, and substation applications-environments where fire safety and thermal durability are critical. Leading producers such as Southwire manufacture these products with conductive copper cores and feature robust outer sheaths that provide reliable protection in both damp and dry settings.

Key Technical Features

Conductor

Constructed from stranded copper or aluminum, this core material allows flexible bending during installation while efficiently carrying current.

XLPE Insulation

Formulated from cross-linked polymer compounds, this layer endures severe thermal stress-maintaining integrity at 90°C in routine service and surviving short-circuit spikes up to 250°C without melting or deforming.

Flame-Retardant Outer Sheath (FR-PVC/FR)

The cable's exterior covering receives special chemical additives that hinder the spread of fire along its length should a short-circuit occur.

Rated Voltage

Engineered for 0.6/1 kV systems, this cable suits low-voltage power distribution and control-circuit installations.
