Durable KK xxxx SB 1000V FEP Electrical Wire 1 2 3 Cores Multicore Screened Cable

The KK xxxx SB Series represents the pinnacle of high-temperature electrical wiring, designed as a durable 1000V FEP electrical wire for the most demanding environments. This multicore screened cable is engineered to meet the rigorous construction requirements of NEMA HP3 and NEMA WC27500, making it a direct equivalent to aerospace-grade hookup wires (similar to M22759 standards).

Whether you require a single core for power distribution or twisted configurations for signal integrity, the KK xxxx SB Series delivers. It is available in 1 core (SB1), 2 cores/twisted pair (SB2), and 3 cores/twisted triple (SB3) configurations. The insulation is made of extruded FEP (fluorinated ethylene propylene), offering superior chemical resistance, low outgassing, and a smooth surface that is easy to strip.

At the heart of the cable lies a high-purity silver plated annealed copper conductor. This construction not only allows for a continuous operating temperature of -90~+200°C but also significantly improves high-frequency performance by reducing the skin effect. With a robust 1000V AC rating, this shielded cable ensures reliable transmission of power and data in avionics, robotics, and heavy industrial machinery.

• 1000V High Voltage Rating - The KK xxxx SB Series is rated for 1000 Volts AC, providing a high safety margin for industrial and aerospace power distribution.
• Versatile Core Configurations - Available as a 1, 2, or 3 cores multicore screened cable, single core for general interconnects, twisted pair for noise cancellation, twisted triple for 3-phase sensors or complex logic.
• Extreme Temperature Resistance - Operates continuously from -90°C to +200°C. The FEP insulation remains flexible in cryogenic conditions and stable in extreme heat.
• Silver Plated Conductor - The use of electrolytic silver-plated copper prevents corrosion at high temperatures and enhances conductivity for high-frequency applications.
• NEMA HP3 & NEMA 27500 Standard - Manufactured to the strict specifications of NEMA HP3, ensuring consistent wall thickness, high dielectric strength, and mechanical durability.
• Superior Shielding - Each configuration features a high-coverage shield (typically silver-plated copper braid) to protect sensitive signals from EMI/RFI interference.
• Chemical & Fluid Resistance - The FEP jacket is virtually inert to fuels, oils, acids, and solvents, making it ideal for engine compartments and chemical processing areas.

Aerospace & Defense - Due to its NEMA HP3 and NEMA 27500 standards and FEP construction, this 1000V wire is extensively used in aircraft wiring harnesses, avionics bays, and flight control systems.

Automation & Robotics - The multicore screened cable (especially SB2 and SB3) is perfect for robotic arms and CNC machinery. The twisted pair/triple construction minimizes crosstalk between signal and power lines, while the flexible silver-plated stranding withstands repeated bending cycles in dynamic motion control.

Semiconductor Manufacturing - FEP has very low outgassing properties, making this wire suitable for internal wiring inside vacuum chambers and wafer processing tools. It withstands the harsh plasma environments and prevents contamination in sensitive semiconductor fabrication processes.

Medical Equipment - The chemical resistance of FEP protects the wiring from harsh disinfectants and sterilization agents. This makes the KK xxxx SB Series ideal for diagnostic imaging devices (like CT/MRI scanners) and surgical robots that require repeated cleaning cycles and high reliability.

Energy & Power Generation - With a continuous operating temperature of +200°C and a 1000V rating, this multicore screened cable is used in power plants, wind turbines, and near industrial engines where high heat and voltage stability are required for safe power transmission.
