STAINLESS STEEL CABLE ADVANTAGE
SSI constructs stainless steel cable by drawing a stainless steel jacket over a thin copper outer conductor. The stainless steel jacket gives the cable superior mechanical strength, shielding and corrosion resistance while the copper outer conductor provides optimum conductivity. SSI offers stainless steel cable in .093, .145, and .240-inch outer diameters with solid, medium loss, and low loss PTFE dielectrics. Steel inner conductor in place of copper is also an option. Special diameters available upon request
The welded cable/connector joint also improves performance at cryogenic temperatures (below 80 degrees Kelvin). Standard soldered joints tend to crack and fail at these low temperatures, but SSI’s welded connections continue to provide reliable service.
Stresses that are not rejected in a copper cable assembly are absorbed in the metal as cold working (work hardening), fatigue, and eventual failure of either the copper jacket of the tin-lead solder joint. A stainless steel assembly will experience much less fatigue and failure than a non-ferrous jacketed cable during the common stress of installation, vibrations, and shock.
