Cable Assemblies

SSI’s stainless steel coaxial cable assemblies have 100% reliability rating. These carefully constructed coaxial cable assemblies incorporate a stainless steel jacketed coaxial cable with welded cable/connector interfaces. The additional strength and corrosion resistance of these assemblies is a definite advantage in extreme mechanical or atmospheric environments. Whether during installation or because of environmental stresses, soldered cable/connector failure will result in increased cost through system downtime, fault isolation, and replacement. The stainless-steel advantage is clear.

Semi-rigid coaxial cable has a solid outer conductor and is manufactured by drawing seamless tubing over the insulating material and center conductor. It is electrically superior to flexible cable with 100% shielding effectiveness, generally lower loss, extended frequency range, and uniform impedance. Typical outer conductors are aluminum or copper, either of which may be tin-plated. The center conductor is usually solid silver-plated copper, which has the advantage of being non-magnetic with loss. Silver-plated copper clad steel center conductor is also available.

A typical flexible coaxial cable has an outer conductor made of fine silver-plated copper wires braided over the insulation material. Other outer conductors use wide silver-plated copper strips braided in a basket weave configuration, or hundreds of silver-plated copper wires running parallel to one another in a long spiral. Stranded, flexible center conductors are common in flexible cable. Coaxial cables with stranded center conductor and braided outer conductors are intended for use in applications where the cable must flex repeatedly while in service but will exhibit higher attenuation as compared to cables with solid center conductors.

Wire harness assemblies consist of a wide range of connectors, wire, coax, etc. We can even build hybrid assemblies that contain hookup wire as well as coax in a single bundle. Connectors range from circular connectors, terminal blocks and boards, d-sub, micro d-sub, audio connectors, single contacts, terminal lugs, splices and bare or tinned wire preps. Wire ranges from 36AWG on up to 0AWG are typical and can either be bundled with spot ties, shielding braid, nylon braid, shrink sleeve or other outer jacketing. Coax terminations in a multi-wire assembly are based on the circular connector compatibility but can also be any coax connection outside of the circular connectors.

Delay lines are used to introduce a time difference (delay) between an input and output of a system. Delay lines can be as precise as just a few milliseconds, microseconds, nanoseconds or picoseconds in electrical delay length. Delay lines can be made from stainless steel, semirigid, and even flexible cable with any type of connectors compatible with the cable material. These assemblies can either be measured in phase length, based on frequency or electrical length (time delay).
