Mechanical Construction
IW’s composite cables provide a myriad of options. Components can include individually shielded and jacketed signal transmission cables, power cables, microwave cables and fiber optic.
Depending on the application, cables can be optimized to address issues such as hydrostatic pressure, tensile loads, concentrated compression points, etc. Overall shielding can be provided with ferrous or nonferrous
materials.
High performance, non-metallic braids and strength members, such as Kevlar™ are also available.
Markets and Applications
IW’s custom cables serve a diverse range of sectors including aerospace, military, telecommunications, medical electronics, and geothermal exploration. Each cable is crafted to handle the specific challenges of its application, ensuring optimal performance under the most demanding conditions.
Application Example
One example is a multiconductor assembly used on a submarine application which includes twisted pair, twisted triple, 16AWG and custom coaxial cable. The bulk cable is manufactured at Insulated Wire’s Long Island, NY facility with the coaxial connectors and cable assemblies prepared at IW MicrowaveProducts Division facility in Bethel, CT.
The cable was produced for a submarine application and contains multiple, individual signal cables and IW’s Tuf-Flex™ microwave cables for use at frequencies up to 18 GHz.
Water block fillers and binders are incorporated under a double braided Sn/Cu braid and polyurethane jacket. Cable withstands the anticipated environmental extremes in accordance with the method requirements of MIL-DTL- 24643B par 4.8.8 and can withstand hydrostatic pressure up to 1050 psi.
