Insulated Wire (IW), founded in 1970, pioneered a unique PTFE lamination process that revolutionised wire and cable manufacturing by achieving unprecedented reliability and smaller diameters. This innovation, combined with a patented shield design, positioned IW as a global leader in low-loss microwave transmission lines utilising both solid and expanded PTFE dielectrics.

In 1988, IW established its Microwave Products Division, expanding its capabilities to include high-frequency coaxial cable assemblies designed for the most demanding aerospace, defence, and communications environments. Today, IW designs and manufactures a wide range of precision cables that support frequencies up to 67 GHz and come in diameters from 0.050” to 0.500”. The company offers a broad selection of SMA, 2.92 mm, 2.4 mm, N-Type, TNC, and 7/16 DIN connectors to meet specific customer requirements.

Headquartered in Bayport, New York, with its Microwave Products Division based in Bethel, Connecticut, IW’s facilities are AS9100 and ISO 9001 certified and staffed by IPC/WHMA-A-620 trained technicians. Every assembly is tested for VSWR and insertion loss, with phase-matching, amplitude-matching, and time-delay calibration available up to 67 GHz.

IW supports a wide range of military, aerospace, and commercial markets, including:

• Telecommunications and data links
• Satellite systems (SatCom)
• Airborne electronic warfare (EW) and countermeasures
• Missile systems and UAV applications
• Avionics, instrumentation, and fire-control systems
• Medical electronics and geophysical exploration

Engineering and environmental testing services are available in-house and through certified laboratories, covering humidity, salt spray, vibration, thermal shock, flex testing, and more. IW’s technical support team also provides custom cable/connector configuration guidance for rack systems and critical RF assemblies.

Insulated Wire’s complete range of low-loss, Re-Flex™, Tuf-Flex™, and semi-rigid cable assemblies is available in Australia through Rojone Pty Ltd – your trusted partner for aerospace-grade interconnect solutions.
