Brazilian Temperature Measuring Optical Cable Factory

Cablena in Brazil produces optical cables, and fiber optic temperature sensing solutions are available from global and regional providers for industrial and power applications.

Brazilian Manufacturers

Cablena is a Brazilian company that manufactures optical, automotive, and power cables with a focus on quality and environmental responsibility . While their website highlights optical cable production, integrating temperature sensing capabilities typically involves combining these cables with fiber optic sensors from specialized providers.

Fiber Optic Temperature Sensing Technologies

Fiber optic temperature measurement in industrial and power applications relies on distributed temperature sensing (DTS) and point sensors:

  • INNO offers a cable temperature monitoring system combining fluorescent point sensors for precise hotspot detection at cable joints and Raman backscattering DTS for continuous monitoring along the entire cable route, up to 50+ km per channel . This system is ideal for high-voltage and underground cables, enabling dynamic cable rating and predictive maintenance.
  • Yokogawa América do Sul provides the DTSX fiber optic temperature sensor, capable of monitoring large areas or entire factories in real time. It supports predictive maintenance by detecting temperature anomalies early, reducing downtime and labor-intensive inspections .
  • COMEM Group produces fiber optic sensors using Gallium Arsenide (GaAs) crystals, offering high accuracy in environments with electromagnetic interference, high voltage, or strong magnetic fields. These sensors are fully dielectric and non-metallic, ensuring immunity to EMI/RFI and microwave emissions .
  • OSENSA develops fiber optic temperature sensing solutions for industrial applications, including switchgear, transformers, and data centers, providing continuous monitoring and partial discharge detection .

Applications

These temperature-measuring optical cables are used for:

  • Power cable monitoring: Detecting hotspots in high-voltage underground or transmission cables.
  • Industrial plants: Monitoring equipment and production lines for predictive maintenance.
  • Critical infrastructure: Ensuring safety and reliability in data centers, switchgear, and transformers.

Summary

While Cablena is a primary Brazilian manufacturer of optical cables, integrating temperature measurement typically involves pairing these cables with specialized fiber optic sensors from companies like INNO, Yokogawa, COMEM, or OSENSA. These solutions provide real-time, distributed, and highly accurate temperature monitoring, essential for predictive maintenance, safety, and operational efficiency in industrial and power applications.
