Insulated Wire

Insulated wire from California Fine Wire Co. is used across industries where precision, reliability, and durability are critical. These include aerospace systems, defense electronics, medical devices, scientific instruments, and advanced research applications. Whether transmitting signals in satellites or powering life-saving medical equipment, the insulation helps maintain performance and safety under demanding conditions.

The wire is manufactured to meet strict dimensional tolerances, making it compatible with a variety of insulated wire connectors. These connectors protect exposed conductors and simplify assembly in compact or high-density configurations. Careful control of insulation thickness and flexibility helps maintain a secure fit and dependable contact during integration.

We use over 25 enameling machines to apply insulation coatings with consistent thickness and high dielectric strength. Each batch is processed under tightly controlled conditions to achieve specific thermal, chemical, and electrical properties. Quality is ensured through rigorous inspection and testing at multiple stages throughout the manufacturing process. California Fine Wire is ISO 9001 certified and fully compliant with key industry regulations, including DFARS, REACH, RoHS, and ITAR requirements.

Wire is available in a range of diameters from 0.001″ to 0.020″. It can be cut to lengths as short as 0.125″ or provided in long continuous spools. Packaging options are selected based on customer needs, from small quantities for prototypes to larger runs for production environments.

Insulated wire from California Fine Wire Co. is lightweight and consistent. The insulation resists heat, chemicals, and mechanical stress, making it reliable under variable environmental conditions. It works well with insulated wire connectors, soldering, and wrapping applications—whether used in low-voltage signal lines or high-reliability power paths.
