Cable Assembly Case Studies

Full chime night 1

Detecting gravity waves – the CHIME telescope project

The CHIME radio telescope was under construction at the Dominion Radio Astrophysical Observatory in British Columbia, Canada and and required specialized cable assemblies with high signal velocity capabilities.

Oil and Gas Offshore Platform

Developing a rugged cable assembly for seismic data

A client had two challenges for us to solve. The first was a torque problem due to the wear and tear from movement during use of the cable assembly. The second was from local camels that had wandered into the area and were chewing through the cable assemblies.

Cable Assembly Capabilities

We can manufacture a wide range of cable assemblies. Below you will find specific details from process and testing to materials we work with. While we have tried to be exhaustive in our listings, due to the ever changing nature of the industry, please contact us if you do not see a specific requirement listed.
