Abstract
The invention discloses an aerospace tensile power cable which comprises a cable core. The cable core comprises an I-shaped nylon framework. Wire cores are placed on the left side and the right side of the I-shaped nylon framework respectively. Each wire core comprises an oval nylon framework coated with waterproof glue. Elastic cushion plates are placed inside the oval nylon frameworks. Conductors are placed on the two sides of each elastic cushion plate respectively. Each conductor is sequentially coated with an aluminum magnesium alloy wire braided shielding layer and an inflaming retarding silica gel inner sheath. The cable core is sequentially coated with a steel wire braided tensile cylinder, a carbon fiber yarn braided layer, an aluminum foil taped covering and an outer sheath. The aerospace tensile power cable is excellent in electrical characteristic, mechanical characteristic and high and low temperature characteristic, low in friction performance, resistant to chemical and weather and incapable of combustion.
