Mica-Wrapped Shielded High-Temperature Cable, GN500 Series
Core parameters include an outside tin-plated copper wire entire shielding layer, a mica wrapping and fibreglass double insulation structure, and a long-term operating temperature of up to 500°C.
Shielding Performance: Millivolt-level thermal signal drift is prevented and electromagnetic interference is effectively isolated in hot running workshops with a total shielding coverage of ≥95%.
Appropriate Situations: Short-term contact with high-temperature workpiece surfaces is made possible by close-range signal calibration operations around ultrahigh temperature dies in hot runners.
KFFP High-Temperature Shielded Fluoroplastic Insulated Cable
Core Specifications: Integrated dual-layer copper wire braided shielding structure (splitter + main shield), long-term temperature resistance of 260°C, short-term peak temperature resistance of up to 500°C, and use of fluoroplastic insulation material.
Shielding Performance: Fully satisfies the high-precision transmission requirements of thermocouples and RTD signals in hot runners thanks to its double-layer shielding design and superior anti-common-mode interference capacity.
Appropriate Situations: Oil-resistant long-term cabling in typical hot , high-temperature regions. Corrosion-resistant and appropriate for intricate work environments in injection moulding facilities
Mineral Insulated Shielded Cable at High Temperatures (MI Cable)
Core Specifications: Long-term temperature resistance of up to 600°C is achieved through the use of magnesium oxide mineral insulation material. The exterior layer of protection is made of seamless copper tubing.
Shielding Performance: Seamless metal tubing has exceptionally high mechanical protective qualities and offers 100% full shielding, totally removing external electromagnetic interference.
Appropriate Situations: Fixed cabling in hot runner systems with extreme heat. The service life is over ten times longer than that of regular cables.
Considerations for Selection: Because of its most reliable shielding and temperature endurance, mineral insulated MI cables are recommended for long-term continuous operation scenarios exceeding 500°C. GN500 mica-wrapped shielded cables are more economical for short-term peak conditions of 500°C. To optimise anti-interference effects and stop anomalous signal transmission, make sure the shielding layer is properly grounded for all models.
These cables are ideal for high-temperature calibration operations of hot runner signal generators and fully satisfy your requirements for temperature resistance above 500°C and superior shielding performance.
