Steel strand bracket for temperature-sensing optical cable

Steel strand brackets provide secure, durable support for temperature-sensing optical cables, ensuring proper alignment, minimal sag, and protection in high-temperature or industrial environments.

Types of Brackets and Mounting Solutions

L Brackets and T Clips: Constructed from stainless steel or mild steel, L brackets are commonly used to support linear sensor cables above cable trays, preventing obstruction and maintaining proper positioning relative to structural members. T clips offer a simple, economical method to fix sensor cables from heat-absorbent surfaces, helping prevent sag and ensuring consistent sensor performance.

Strand-

Based Storage Brackets: For optical cables installed on aerial strand wires, stainless steel and UV-resistant plastics are used to create durable storage brackets. These brackets securely hold fiber optic loop reserves, prevent deformation, and protect cables from mechanical stress or sag over long-term installations.

Sensor-

Specific Mounting Brackets: Brackets designed for photoelectric or fiber sensors, such as flexible square shaft or CZ-SW type brackets, provide secure attachment and alignment. These are typically made from high-strength materials like aluminum or PA (66N) black plastic, offering vibration resistance and adaptability for industrial setups.

Material Considerations

Stainless Steel: Offers corrosion resistance, high strength, and suitability for outdoor or high-temperature environments. Ideal for long-term installations of temperature-sensing optical cables. Mild Steel: Suitable for indoor or less demanding environments, often coated or painted for corrosion protection.

UV-Resistant Plastics: Used in combination with steel for strand-based storage brackets to prevent deformation and maintain cable integrity. Compatibility with Temperature-Sensing Optical CablesHigh-temperature sensing optical cables, such as DTS steel-armored variants, can operate in ranges from -40 °C to +300 °C depending on the fiber type and construction. Brackets must accommodate the cable diameter, provide strain relief, and allow for thermal expansion without damaging the fiber.

Tubular spot-welded grating sensors integrated into steel strands demonstrate that steel-based mounting can maintain high measurement accuracy and repeatability under varying temperatures.

Installation Tips

Ensure brackets are spaced to prevent cable sag and maintain sensor accuracy. Use stainless steel fasteners for outdoor or high-temperature applications. For strand-mounted cables, secure loops or excess cable in storage brackets to avoid mechanical stress.

Verify that the bracket design allows for easy inspection and maintenance of the optical cable. By selecting the appropriate steel strand bracket type and material, temperature-sensing optical cables can be securely mounted, protected from mechanical stress, and maintained for accurate long-term monitoring in industrial or structural applications.
