Mass & diameter
Assess per-meter mass and routing impact at full-harness scale.

SPACE / 06
Design directions for spacecraft data, power and RF interconnects, with emphasis on low mass, vacuum material behavior, thermal cycling, vibration, routing constraints and lot traceability.

01 / PRODUCT OVERVIEW
This information supports product direction and early technical discussions. Yidong Telecom defines final materials, dimensions and manufacturing around the actual interface, environment and validation target.
Assess per-meter mass and routing impact at full-harness scale.
Consider outgassing, volatiles, contamination control and traceability.
Evaluate thermal cycling, vibration and assembly stress.
Build evidence from material lots through process records and lot tests.
02 / PRODUCT TYPES
Each type must be further defined by protocol, length, installation and environmental conditions. A category name is not a fixed specification.
Lightweight space-wire direction tailored around conductors, thin-wall insulation, temperature and assembly.
