The temperature-sensing optical cable is placed inside a stainless steel threaded tube, with Kevlar tightly wrapped and stainless steel wire tightly woven outside the threaded tube for reinforcement. The outer layer is protected by a flame-retardant LSZH sheath. The sensing fibre is a multimode fibre that meets international standards and has excellent Raman scattering characteristics.
• Fibre optic cable armor protection with excellent mechanical properties
• Small outer diameter, simple structure, fast thermal penetration, fast temperature measurement response
• Being compatible with existing 1310 nm equipment
• Flame retardant LSZH outer sheath, good electrical insulation performance
• Fibre optic cables are soft and have good toughness, making them easy to lay out during construction
• Temperature measurement of urban underground pipe gallery
• Temperature measurement of cables and busbars
