Green PFA Wire (Silver-Plated Copper) | 19/0.28, 2mm OD, 250°C, 600V

Unmatched Performance in Extreme Environments: High-Temperature, Chemical-Resistant Green Wiring

In demanding applications where conventional wiring fails due to extreme temperatures, harsh chemicals, or high electrical stress, a superior solution is required. Standard PVC or even PTFE wires just can't withstand the rigorous conditions found in industrial, aerospace, and laboratory settings.

Our Green PFA Wire is engineered for precisely these challenges. This high-performance wire features a silver-plated copper conductor (19/0.28 stranding) encased in a robust Perfluoroalkoxy (PFA) insulation, presented in a distinct, professional green finish. Designed to operate reliably at continuous temperatures up to 250°C and rated for 600V, it offers exceptional chemical resistance, superior dielectric strength, and excellent flexibility. Supplied in convenient 100-meter reels with a 2mm overall diameter, it's the ideal choice for critical wiring where durability, clear circuit identification, and performance are non-negotiable.

Key Features & Benefits

• Extreme Temperature Resistance: Reliably performs in continuous operating temperatures up to 250°C, making it perfect for high-heat environments.

• High Voltage Rating: Rated for 600V, ensuring safe and stable electrical transmission in demanding systems.

• Superior Chemical Resistance: PFA insulation provides excellent resistance to a wide range of aggressive chemicals, solvents, oils, and fuels, preventing degradation.

• Silver-Plated Copper Conductor: Features 19 strands of 0.28mm silver-plated copper (19/0.28). The silver plating enhances conductivity, improves high-temperature performance, and offers superior corrosion resistance compared to bare copper.

• Enhanced Flexibility & Durability: The stranded conductor (19/0.28) offers excellent flexibility, making installation easier, while the robust PFA insulation provides superior mechanical strength and resistance to cracking.

• Clear Green Finish: The green insulation provides distinct colour-coding for easy circuit identification, often used for grounding or specific signal lines, and a professional appearance within complex wiring systems.

• Low Gas Permeability: PFA's inherent properties make it highly resistant to gas and vapor permeation, crucial for vacuum or sealed applications.

• Excellent Dielectric Properties: Maintains high electrical insulation properties even at elevated temperatures and frequencies.

• Standard 2mm Overall Diameter: Offers a compact profile, ideal for applications where space is limited.

• Convenient 100m Reel: Supplied in a practical 100-meter length, perfect for various projects and installations.

Understanding PFA Wire Construction

• PFA (Perfluoroalkoxy) Insulation: A high-performance fluoropolymer with properties similar to PTFE but with the added advantage of being melt-processable. It offers excellent thermal stability, chemical inertness, and superior electrical properties, making it ideal for harsh environments.

• Silver-Plated Copper (SPC) Conductor: Combines the high electrical conductivity of copper with the enhanced corrosion resistance, improved high-temperature performance, and superior solderability of silver. The silver layer also helps reduce resistance at high frequencies (skin effect).

• 19/0.28 Stranding: This notation indicates the conductor's construction:

  • 19: The number of individual strands of wire.

  • 0.28: The diameter (in millimeters) of each individual strand.

    This multi-stranded construction provides greater flexibility and resistance to fatigue compared to a solid conductor, while maintaining excellent current-carrying capacity.

Important Installation & Safety Notice

Installation of PFA wire should only be performed by qualified and competent personnel in accordance with all local electrical codes, safety regulations, and application-specific requirements. While PFA offers excellent chemical resistance, always verify compatibility with specific chemicals or extreme conditions. Ensure proper termination and insulation to maintain the wire's performance and safety ratings.

Frequently Asked Questions (FAQs)

Q1: What are the main advantages of PFA wire over standard PTFE or PVC wire?

A1: PFA wire offers a higher continuous operating temperature (250°C vs. typically 200°C for PTFE and much lower for PVC), superior flex life, better resistance to stress cracking, and excellent chemical inertness. It also retains good electrical properties across a wide temperature range.

Q2: What does "silver-plated copper" mean, and why is it used?

A2: Silver-plated copper (SPC) wire has a copper core coated with a thin layer of silver. This combination leverages copper's excellent conductivity and strength with silver's superior corrosion resistance, better performance at high temperatures, and improved solderability. It's especially beneficial in high-frequency applications due to the "skin effect."

Q3: Can this wire be used in outdoor applications?

A3: PFA has excellent resistance to weathering, UV, and ozone. While the wire itself is highly durable, for outdoor applications, ensure that all connections and terminations are properly sealed and protected to maintain the overall integrity and safety of the electrical system against moisture and physical damage.

Q4: What does "19/0.28" refer to in the wire's description?

A4: This describes the conductor's construction. It means the conductor is made up of 19 individual strands of wire, and each of those strands has a diameter of 0.28 millimeters. This multi-stranded design provides flexibility and resistance to fatigue.

Q5: Is this wire suitable for use in hazardous (e.g., ATEX) areas?

A5: While PFA wire has excellent properties, its suitability for hazardous (explosion-risk) areas depends on the specific ATEX certification of the entire cable assembly and installation. This product is the wire itself. Always consult relevant safety standards and ensure the complete system is certified for such environments.
