Specialist high performance wire made in the US

nsulated Wire is a New York based designer and manufacturer of all types of electrical wire and cable products, including coaxial cable. The company was
founded in 1970 focusing on the oil and gas market, with the initial product being developed using a unique process for laminating Teflon, to realise a cable that provided higher breakdown voltage using a smaller line size than was available at the time. This evolved into a range of wire products which are still widely used in data logging for oil exploration today – with core materials of Teflon and silver-plated copper providing reliable operation at high temperature in harsh environments. During the 1980s, the lamination process was applied
to coaxial cable, and the company started producing a range of line sizes to support applications in the RF, microwave and millimeter-wave frequency ranges that ultimately lead to the range of coaxial cable Insulated Wire supplies today. For coax cable, the advantages of the company’s
manufac-turing process enables a concentric cable construction that provides tight impedance control, excellent phase stability and exceptional attenuation performance across the microwave spectrum. All cable designs are double shielded using FEP outer jacket as standard and also available with various jacket material options including Santoprene, Low Smoke/Zero Halogen polyurethane and Tefzel, armor and other abrasion resistant materials. The attenuation performance of Insulated Wire’s coax makes these cable types suitable for applications
where the lowest loss between antenna and the electronic system is the primary consideration and one of the key reasons why cables like its 280 series (19.5GHz cut-off) are used on marine platforms worldwide. Insulated Wire can supply either turn-key cable assemblies, part terminated to support intricate routing requirements, or bulk cable and connector kits to enable assembly and installation at a customer location. From down mast cables on surface ships to hull penetrators and periscope cables, Insulated Wire is experienced in providing solutions for harsh environment applications. In addition to bulk cable, Insulated Wire also offers composite cable solutions – which can be same or mixed signal cable types, and can also ruggedise fibre optic cables and incorporate them into a composite cable design. Insulated Wire works closely with its customers’ engineering teams to ensure that all requirements are documented and projects managed through qualification and delivery of the final design. For RF/microwave cable assemblies, Insulated
Wire offers a wide range of interconnect solutions using industry standard interfaces, from high-power/ low-frequency to millimeter-wave including 3 1/8 and 1 5/8 EIA flanges, SC, C, HN, N-type (18GHz), TNCA (18GHz), SMA, 3.5mm, 2.92mm, 1.85mm and 1.0mm. All connectors provide optimum electrical performance and reliability. Insulated Wire has two facilities: Bayport NY
for bulk cable manufacture and Ronkonkoma, NY, that produces assemblies, with AS9100 campus certification. With US-based manufacturing and the support of a worldwide network of representatives and agents, Insulated Wire can offer standard and custom wire and cable assemblies and offer customers a secure supply chain.
Cables and assemblies for EMC/EMI compliance testing Insulated Wire has been supporting EMC customers with coaxial cable and assemblies for decades. From smaller EMC test houses, compliance labs and both military and commercial market OEMs across the world, its cables provide reliable, consistent performance for EMC/EMI compliance testing. The company provides large-diameter/high-power flexible
