Back to list DJ-GC-GTGJ-2S Double-layer Bite High Temperature Armored Sensing Optical Cable up to 385℃ - for Oil Fields

The Double-Layer Armored High-Temperature Sensing Fiber Optic Cable for Oilfield Applications, capable of withstanding temperatures up to 385°C, offers several advantages:


1. Extreme temperature resistance: Designed to operate in high-temperature environments up to 385°C, this fiber optic cable can endure the intense heat commonly found in oilfield operations. It ensures reliable communication and sensing capabilities in extreme conditions.


2. Double-layer armored protection: The dual-layer armor provides enhanced protection against mechanical stress, abrasion, and moisture, making the cable highly durable and suitable for harsh oilfield environments. It ensures the longevity and reliability of the communication and sensing system.


3. Sensing capabilities: In addition to its communication function, this fiber optic cable features sensing capabilities that allow for monitoring and data collection within the oilfield. It can be utilized for real-time temperature, pressure, and vibration sensing, providing valuable information for operational efficiency and safety.


4. Resilience to oil and chemicals: The cable's materials are resistant to oil, chemicals, and other corrosive substances typically present in oilfield environments. This resistance prevents damage and ensures consistent performance over time, reducing maintenance needs and downtime.


5. Enhanced safety and reliability: The high-temperature sensing fiber optic cable improves operational safety by providing accurate and timely data for monitoring critical parameters. Its reliability in extreme conditions minimizes the risk of communication failures or sensor malfunctions, enhancing the overall safety of oilfield operations.


6. Customizable solutions: Manufacturers may offer customizable options for the cable's length, connectors, and sensing capabilities to meet specific oilfield requirements. This flexibility allows for tailored solutions for different applications within the oil and gas industry.
