K xxxx SB Series 600V 200℃ FEP Silver-Plated Copper Shielded Wire for Internal Wiring

The K xxxx SB Series is a high-reliability 600V Shielded Wire specifically engineered for internal wiring applications within control panels, machinery, and instrumentation. Constructed with Extruded FEP (Fluorinated Ethylene Propylene) insulation, this cable offers a unique combination of chemical inertness, low outgassing, and high dielectric strength, making it ideal for compact and demanding electronic assemblies.

Manufactured in accordance with the construction and material requirements of NEMA HP3 and NEMA WC27500, this shielded wire ensures that every meter meets the rigorous standards. It operates continuously from -90°C to +200°C, providing exceptional thermal stability near heat-generating components like transformers and resistors.

The conductor is composed of high-purity silver plated copper, which not only improves conductivity at high frequencies but also enhances heat resistance. For applications involving vibration or tight bending radii, an SCA (silver plated copper alloy) option is available to prevent conductor fatigue.

Whether you need single conductor (SB1), twisted pairs (SB2), or twisted triples (SB3), this series delivers the signal integrity and durability required for precision internal interconnects. Custom core counts are also available upon request to meet specific design requirements.

• NEMA-Based Construction - While optimized for industrial internal wiring, the shieded wire is built to the specifications of NEMA HP3 and NEMA WC27500, ensuring superior insulation consistency and material quality compared to generic hook-up wires.
• Optimized for Internal Wiring - The FEP insulation is tough yet thin-walled, saving valuable space inside control cabinets and junction boxes while resisting abrasion from sharp metal edges.
• 600V & 200°C Rating - A robust 600 Volt rating combined with a +200°C continuous operating temperature allows this wire to handle power, control, and signal duties in close proximity to hot components.
• High-Frequency Performance - The silver plated copper conductor minimizes the "skin effect" at high frequencies, making this shielded wire excellent for data transmission and precision analog signals.
• Vibration-Resistant SCA Option - The optional SCA (Silver Plated Copper Alloy) conductor provides extra tensile strength, crucial for internal wiring in moving parts or high-vibration machinery.
• Superior Chemical Resistance - FEP is virtually inert to most industrial chemicals, oils, and solvents, protecting the internal wiring harness from corrosion in harsh processing environments.
• Versatile Configurations - Available in SB1 (Single Core), SB2 (Twisted Pairs) and SB3 (Twisted Triples) to support various internal connection needs, from power distribution to encoder feedback.

Control Panel & Switchgear Assembly - As internal wiring, the K xxxx SB Series connects relays, terminals, and PLCs. Its 600V rating and flame-retardant FEP insulation ensure safety and reliability in high-density electrical cabinets.

Semiconductor & Vacuum Equipment - FEP has very low outgassing properties. This makes the wire suitable for internal wiring inside vacuum chambers or semiconductor processing tools where contamination must be minimized.

Robotics & Motion Control - Inside the arm of a robot, space is limited and movement is constant. The SCA conductor and flexible stranding allow this wire to route through tight bends and withstand the dynamic flexing of internal joints.

Aerospace Ground Support Equipment (GSE) - Since the shielded cable is manufactured to NEMA HP3/WC27500 standards, it is frequently used in GSE and avionics test benches where aerospace-grade performance is required.

Medical & Analytical Instruments - The chemical resistance of FEP protects the wiring from disinfectants and reagents, while the high-temperature rating allows for sterilization cycles (autoclaving) in certain medical device applications.

A: FEP can withstand much higher temperatures (200°C vs 105°C) and is chemically inert. In tight control panels where heat builds up, FEP won't shrink or crack like PVC, ensuring long-term reliability for your internal connections.

A: Yes, the 600V rating and tough shielding make it suitable for external use. However, it is primarily optimized as a high-performance component wire or hook-up wire for internal assemblies.

A: It is manufactured according to the construction guidelines of NEMA HP3 and NEMA WC27500. This means we use the same high-grade materials and stranding patterns defined in those standards to ensure you get aerospace-level quality for your industrial applications.

A: Yes, FEP is virtually inert. It resists almost all industrial chemicals, including acids, alkalis, solvents, oils, and fuels. This makes it an excellent choice for wiring inside chemical processing equipment or machines that use harsh cleaning agents.

A: The K xxxx SB Series is rated for continuous operation from -90°C to +200°C. It remains flexible in cryogenic conditions and will not melt or degrade in extreme heat, unlike PVC or rubber wires.

A: Yes. While we stock standard colors (black, white, red, green, etc.), we can accommodate custom color codes or printed legends (e.g., part numbers, voltage ratings) on the FEP insulation for large volume orders to assist with your internal wiring identification.

A: Single core (SB1) items are often available from stock. Twisted configurations (SB2, SB3) usually require a short processing time for twisting and shielding, typically ranging from 10 to 15 days depending on the quantity.
