60 miles of copper wire, weighing many thousands of pounds resulting in increased carbon dioxide emissions. Connector backshells shall be potted and molded, or use stress relief boots as required, in accordance with applicable engineering documentation. Coaxial cable (flexible, semi-rigid, rigid) and fiber optic cables shall exhibit a neatly organized layout, with smooth bends and sufficient stress relief. Harnesses exhibit a neatly organized layout with smooth bends and sufficient stress relief.
The mating surfaces of all unmated connectors shall be protected by covers during storage, handling and installation.
The cable assembly meets dimensional, layout and design requirements and exhibits a smooth, flat profile with no visible damage to the connectors or the insulation.
Heat shrink sections are properly installed, tightly shrunk and the termination is visible. Connector backshells, adapters and clamps shall be assembled and torqued per engineering documentation. Excess thread protrusion represents an assembly, interference and electrical separation problem, as well as adds unnecessary weight to the assembly. Cables containing discrete conductors shall be fabricated in one or more layers, by winding the conductors together uniformly. Ties are neat, tight and properly spaced (relative to harness diameter) to maintain the wiring in a tight, neat bundle.
Plastic straps should have metal tangs that lock securely into the ribbed portion of the strap.


Slight scuffing or discoloration is acceptable, provided there is no impact to form, fit or function, and there is no exposure of base metal. The cable does not exhibit evidence of insulation damage, such as cuts, nicks, scrapes, crushing, cold flow or burns.
The ends of glass braid may be bonded by use of adhesive, and then secured by spot tie or other means to prevent movement on the wire bundle. Shield ground leads terminated in a dasy-chain configuration are susceptible to a single-point failure, should one of the links break. The splice exhibits a smooth profile, proper strain relief and is located in an area of the harness not subjected to flexure.
Metal braid sleeving may be installed over harnesses by either direct weave or by use of prewoven tubing.
Polyimide or nylon braids (for use on ground support equipment) may have their ends sealed by use of a "hot knife" or similar instrument. The solder sleeve has not been completely shrunk and is improperly positioned, resulting in a poor fit that does not provide a good mechanical grip or seal, and which does not meet minimum overlap requirements. The location of splices shall be staggered to minimize the increase in profile to the harness. Unused or spare conductors shall be terminated by folding the unstripped end back on itself and then sealed with insulation sleeving or wrap.
The harness exhibits a bend radius that is less than the minimum recommended for the conductor type(s) used and overall harness diameter. Cables and harnesses shall be routed so that they are protected from abrasion, cold flow, cut through, vibration, chafing, flexing and sharp edges.


Replacement conductors shall be of the same voltage and current rating as the original conductor. Metal braid sleeving shall exhit uniform coverage, to provide electrical and mechanical protection to the underlying harness. Laminate construction of Kapton®, FEP, and Teflon film encasing an etched copper foil conductor. Miniature cryogenic flat cable is utilized to interconnect optical detector cells on a satellite.
Available in multiple combinations of conductor materials, number of conductors, and twisted or straight conductors.
Nanocomp Technologies, Inc., a developer of performance materials and component products from carbon nanotubes (CNTs), today announced it has been selected by the United States Government to supply CNT yarn and sheet material for the program needs of the Department of Defense, as well as to create a path toward commercialization for civilian industrial use. Nanocomp Technologies has committed to building large-scale manufacturing facility, delivering assured supply of superior nanotube-based materials for critical national defense needs.
NCTI has developed novel methods to fabricate its nanotubes into structurally strong and electro-thermally conductive fibers, yarns, and sheets. Nanocomp’s CNT yarn and sheet materials are currently featured within the advanced design programs of several critical DoD and NASA applications.
