It is important to reduce parasitic heat load in designing cryogenic systems. Conductive heat load is dominant below 30K. One of major paths is support structure. A truss structure is often used to support instruments from a spacecraft. We developed a low thermal conductance tube for truss structure below 30K. It has three tubes with different diameter and tube in tube type layout to extend thermal isolation length. Each tube is connected at one end each other. Due to this layout it is about 3 times longer in thermal isolation length than conventional tube.
