TF Wire Twisted Wire 1.25mm² 1.6mm² 2.0mm² Copper PVC Insulated Wire Summary​ TF Wire’s twisted copper PVC insulated wires, available in 1.25mm², 1.6mm², and 2.0mm², are high-performance solutions for signal and power transmission in residential, commercial, and light industrial settings. The twisted pair design is engineered to minimize electromagnetic interference (EMI) and crosstalk, ensuring stable data and power flow—critical for audio-visual systems, security networks, and smart home controls.​ Constructed with 99.9% high-purity copper conductors, these wires deliver exceptional conductivity, reducing signal loss and energy waste. The PVC insulation provides robust protection against moisture, abrasion, and temperature extremes (-15°C to 70°C), making them suitable for indoor, enclosed outdoor, and tight-space installations like wall cavities or conduit runs.​ Sizing aligns with specific needs: 1.25mm² for low-power devices (doorbells, sensors); 1.6mm² for medium applications (intercoms, lighting controls); 2.0mm² for higher-current equipment (security cameras, smart hubs). Compliant with international standards, they feature flame-retardant PVC and flexible construction for easy routing, balancing durability with versatility. Ideal for modern connected systems, these wires ensure reliable performance in EMI-prone environments.
