NASA-CR-2010-216086 Wire and Cable Cold Bending Test

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of NASA-CR-2010-216086 testing. One of the factors in assessing the viability of wire or cable on the lunar surface is its flexibility under extremely cold conditions. Current wire standards did not address their mechanical behavior under cold, cryogenic temperature conditions. Therefore, tests were conducted to provide this information.

To evaluate this property, 35 different pieces of insulated wire and cable were cold soaked in liquid nitrogen. The segments were then subjected to bending and the force was recorded. Any failure in the insulation or coating is also documented for each sample tested.

Bending force tests were performed at room temperature to provide a comparison with the change in force required to bend the samples due to low temperature conditions. Results from bending tests were plotted and showed how various types of insulated wire and cable responded to bending under cold conditions. These results were then used to estimate the torque required to open the wire under these low temperature conditions.

Transferring power is an important aspect of a lunar power system design. The ability to expand the power grid, include additional power generating sources, and scale up as power demands increase, depends on the ability to efficiently and effectively move power from sources to loads.

The power transmission cable consisting of conductive wire and its associated insulation will need to be able to operate and survive in this environment. The effects of the lunar environment will determine the installation, placement and design of the cable. Therefore, an important aspect of cable design will be to understand how these environmental conditions affect the different materials and combinations of materials that could potentially be used in power cable construction.
