CabONE CABLE:: Multi strand House CCA Copper Wire 300 Feet FR PVC"" provides several important details about the wire's construction and specifications. Multi-Strand Construction: This means the wire is composed of multiple smaller strands twisted together, which enhances flexibility and durability. Multi-strand wires are more flexible and less likely to break under repeated bending compared to solid-core wires. Copper: CCA Copper refers to a rod of metal where a layer of copper is clad or bonded onto a core material, which is typically a different metal. Unlike pure copper, which is entirely made of copper, CCA copper combines copper with another metal to achieve certain desired properties. Length: This denotes that the wire is 90 meters long. It’s essential to ensure the length suits your project requirements. Flame Retardant: This signifies that the wire is designed to resist catching fire and will self-extinguish if ignited. This property is crucial for electrical safety, especially in residential and commercial buildings. PVC Insulation: The wire is insulated with PVC, a common material known for its durability, flexibility, and resistance to moisture and chemicals. PVC insulation helps protect the wire from physical damage and electrical shorts"
