Multi-Core Teflon Shielded Cable | 3x3mm² TC/FEP/TCWB/PFA 300/500V High-Temp Cable
Multi-Core Teflon Insulated Sheathed Shielded Cable: Premium Performance for Extreme Environments
Engineered for the most demanding applications, our Multi-Core Teflon Shielded Cable delivers exceptional reliability where standard cables fail. This robust cable, configured with 3 cores of 3mm² each, combines advanced materials—Tinned Copper (TC) conductors, Fluorinated Ethylene Propylene (FEP) insulation, Tinned Copper Wire Braid (TCWB) shielding, and a Perfluoroalkoxy (PFA) outer sheath—to ensure superior performance in high-temperature, chemically aggressive, and electromagnetically noisy environments. It is the definitive solution for aerospace, industrial automation, oil & gas, and military applications where signal integrity and operational safety are critical.
Key Features & Technical Advantages
✔ Exceptional Thermal Stability: The FEP insulation and PFA sheath provide a wide operating temperature range from -60°C to +250°C, ensuring consistent performance in both extreme cold and intense heat.
✔ Superior EMI/RFI Protection: The tinned copper braid shield (TCWB) offers high coverage (typically ≥80%) for effective defense against electromagnetic and radio frequency interference, safeguarding critical signal transmission.
✔ Excellent Chemical & Mechanical Resistance: The PFA sheath provides outstanding resistance to oils, acids, solvents, and abrasion, guaranteeing longevity in harsh industrial settings.
✔ Optimized Electrical Performance: Rated for 300/500V with high dielectric strength, this cable ensures reliable power and signal transmission in medium-voltage applications.
✔ Durable & Flexible Construction: The 3x3mm² tinned copper conductor (7/0.35 stranding) balances current-carrying capacity with flexibility, facilitating easier installation in tight spaces.

FAQ
Q1: What are the main advantages of the FEP and PFA combination?
A: This combination offers the best of both worlds: FEP provides excellent high-temperature resistance and electrical properties, while the PFA sheath adds superior chemical resistance, mechanical durability, and a continuous high-temperature rating up to 250°C, making it ideal for the most demanding environments.
Q2: Is this cable suitable for continuous flexing applications?
A: While the stranded tinned copper conductor provides good flexibility, our standard construction is optimized for fixed installation or applications with limited flexing. For continuous flexing, we recommend our specialized High-Flex Robot Cable series.
Q3: Can you provide custom colors or printing on the cable?
A: Absolutely. We specialize in customization. We can provide a range of sheath colors for circuit identification and add custom printing (such as part numbers, company logos, or safety warnings) to meet your traceability and branding needs.
Q4: What certifications does this cable hold?
A: Our cable is manufactured to meet core international standards and can be customized to comply with UL, CE, RoHS, and specific military standards (e.g., MIL-W-16878) upon request.
Q5: What is your typical lead time for sample requests and bulk orders?
A: We can provide samples for evaluation within 3-5 working days. For bulk production orders, our standard lead time is 2-3 weeks, which can be adjusted based on order volume and customization requirements.
