ET xxxx Y SB 200℃ Polyimide Taped PTFE Wire 250V SPC Shielded Instrumentation Cable

The ET xxxx Y SB Series is a high-performance 250V Shielded Instrumentation Cable engineered for extreme thermal environments. Designed to operate continuously from -90°C to +200°C, it is the ideal solution for aerospace, defense, and industrial applications where standard cables would fail due to heat or chemical exposure.

This series features a conductor of electrolytic silver-plated annealed copper (SPC). The silver plating is critical for high-frequency performance, as it minimizes the "skin effect" and prevents high-temperature oxidation, ensuring stable signal transmission and low attenuation in demanding conditions.

The cable utilizes a specialized insulation system combining PTFE insulation with a Polyimide separating tape. This design offers superior dielectric strength and mechanical protection, while the braided silver-plated copper shield provides 100% coverage against electromagnetic interference (EMI).

Manufactured to NEMA-HP3 and NEMA-WC27500 specifications, the series is available in SB1 (single core), SB2 (twisted pair), and SB3 (twisted triple) configurations. This versatility ensures reliable performance for avionics data buses, sensor inputs, and precision instrumentation circuits.

• Extreme Temperature Rating - Designed to withstand continuous operating temperatures up to +200°C and cryogenic lows of -90°C, making it ideal for near-engine or high-heat industrial zones.
• Advanced Insulation System - Features PTFE insulation for low dielectric loss, protected by a polyimide separating tape that adds an extra layer of thermal and mechanical defense.
• High-Frequency Performance - The use of silver-plated copper (SPC) for both the conductor and the braid minimizes the "skin effect" at high frequencies, ensuring signal integrity in RF and data transmission applications.
• 250V AC Rating - Optimized for instrumentation and control circuits requiring a 250V voltage rating.
• Manufactured to Standards - Produced according to NEMA-HP3 and NEMA-WC27500 specifications, ensuring consistent quality and reliability for aerospace and defense use.
• Versatile Configurations - Available in SB1 (single core), SB2 (twisted pair), and SB3 (twisted triple) structures to suit various wiring harness needs.

Aerospace & Avionics - The +200°C rating and NEMA-HP3 standard make this shielded cable perfect for aircraft wiring harnesses, particularly in zones near engines or exhaust systems.

Industrial Instrumentation - Used in plastic injection molding machines and glass manufacturing equipment. The Polyimide tape and PTFE insulation resist the high heat and chemical exposure found in these heavy industrial processes.

Automotive Testing - Essential for test cells and dynamometers where wires are exposed to extreme heat and vibration. The braided shield protects sensitive sensor data from ignition noise.

Oil & Gas - Suitable for downhole instrumentation where high temperatures are encountered. The Polyimide tape adds a layer of protection against the harsh mechanical environment of drilling.

Medical Equipment - Used in high-temperature sterilization equipment and diagnostic imaging machines (like CT scanners) where thermal stability and signal clarity are critical.
