Cable capabilities

Insulated Wire has the capability to supply composite RF & microwave assemblies for various applications.
With complete control of the manufacturing process, IW is able to offer custom solutions based on standard process and product for many types of applications. IW has supported our customers with custom twisted pairs and triple wire for data transfer, custom impedance RF cables (flexible and semi-rigid), same and mixed wire type composites including fiber and coaxial cable, triple shielded RF cables for operation under HEMP, jacket materials to withstand NBC (Nuclear & Biological Conditions), submersible cables, and short duration/very high temperature conditions in space flight.

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.

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 shown here 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.

Custom design cables

Re-Flex™ , Hand-formable Coax Cables

To provide improved electrical and mechanical performance over traditional hand-formable designs, Insulated Wire presents Re-Flex™.

High Performance 75Ω Coaxial Cables

Insulated Wire (IW) is proud to introduce its line of high-performance 75 ohm coaxial cables.

Semi Rigid Cables

Semi-Rigid Cables

In addition to our range of flexible cables, IW also manufactures semi-rigid cable types at standard line sizes including .047”, .085”, .141” and .250” enabling customers to use a wide range of industry standard interconnect options.

We offer 50 ohm cable as standard product, however as the dielectric is manufactured using the same lamination
technique applied to flexible cables, we’re able to provide customers with custom impedance semi-rigid cables to suit their specific requirements.

All semi-rigid products are available as bare copper or plated finish and can be shipped as coils or cut lengths.
