750°C 300V High Temperature Wire
High Temperature Fiberglass Wire · Mica Insulated
Product application:
Optimized for low-voltage signal and instrumentation circuits in extreme-heat zones. Used for thermocouple extension wiring, sensor connections, and control circuits inside furnaces, smelters, and incinerators where a 300V rating is sufficient but 750°C endurance is mandatory. Ideal for glass furnace instrumentation, steel mill sensor arrays, ceramic kiln monitoring, and aerospace ground-test equipment where compact high-temperature wiring is required for reliable data transmission under sustained extreme thermal loads.
