Overview
In marine geophysical exploration, equipment needs to be lightweight, waterproof and reliable. Whether the application is a marine survey, seismic testing, or an oil and gas exploration, geophysical seismic cables must provide transmission stability despite the aquatic environment — even when submerged.
GORE Bonded Telemetry Pair Cables offer the highest-available transmission stability for marine geophysical exploration applications, with data transmission performance that remains high, consistent and reliable throughout their product life. For over 10 years [may be longer at this point], the cables have provided proven performance and unsurpassed reliability in marine streamer cables around the world.
The cables feature a smaller outer diameter, enhanced flotation characteristics, and the highest-available signal intensity under mechanical stress for streamer cables — providing reliable performance the first time and every time.
The Technology Behind the Cables
Gore’s low dielectric constant, PTFE and expanded PTFE (ePTFE) materials enable the bonding of the pairs. Bonding the cables together allows them to maintain high electrical performance despite physical stressors like bending and pulling, and the ePTFE construction reduces the overall diameter and weight of the cables. The specific location of each insulated, silver-plated conductor bonded throughout the entire length of the pair maximizes the electrical performance and reliability during flex.
We only use the highest quality, multi-layered, concentric and pinhole-free insulations over each conductor. Each material is compatible with streamer fluids, other floatation media, and can operate in wide temperature ranges.
Features & Benefits
Through Gore’s materials science capabilities and bonding technology, we’ve designed our Bonded Telemetry Pair Cables to feature:
- pinhole-free insulation utilizing ePTFE and PTFE insulation material
- no fluid penetration between components
- lightest-available weight
- smallest-available diameter
These features provide manufacturers and end users with:
- longer cable life (reduced overall costs)
- smaller streamer cable diameter
- highest-available signal stability under mechanical stress and movement
- reliable electrical performance in fluids
- lowest-available attenuation
