Ask about this variant ↗Temperature options are selected with the complete construction, exposure duration and installation conditions. Voltage and current capacity depend on the chosen specification.
Typical use
Connections for high-temperature equipment.
Electromagnetic induction heatingHigh-temperature equipment connections
Tell us whether the wire is used in a winding or as a connection lead. Include heating frequency where applicable, conductor size, voltage and current.
Construction & selection
Temperature is the starting point.
Conductor system
Choose the temperature version and specify conductor material, size and current. The 600°C version is nickel-plated; the 800°C version uses pure nickel. The 500°C conductor is confirmed with the selected specification.
Mica insulation
The insulation system is selected for the complete electrical and thermal requirement. Include voltage, exposure duration and finished-diameter limits.
Equipment connection
Describe winding or lead use, the routing, termination and heating frequency where applicable. Include a drawing or reference sample when available.
Inside the mica wire
Four parts of the construction.
The GN catalog illustrations identify the conductor, mica wrapping, fiberglass braid and impregnated finish. Match the complete construction to the requested temperature version.
Conductor
The electrical path. The catalog distinguishes bare copper, nickel-plated copper and pure nickel. Current capacity and termination depend on the selected material and size.
Mica tape wrapping
The wrapped insulation layer around the conductor. Voltage, insulation build and finished diameter belong to the selected model.
Fiberglass braid
The woven covering around the insulation. A glass braid is not the same as a metallic electrical screen.
Impregnated finish
The outer treatment shown in the catalog. Finish and colour are matched to the specified construction rather than identified from a photo alone.
Replacing a wire from the older GN catalog?
Include the full model suffix. Older GN500-01, GN500-02 and GN500-03 references must not be substituted directly for the current 500°C, 600°C and 800°C options using temperature alone.

Catalog nominal sizes: 0.5, 0.75, 1, 1.5, 2, 2.5, 4, 6, 10, 16, 25, 35, 50 and 70 mm²; GN500-02 and GN500-03 also list 95 mm². These are reference sizes, not a stock or current-version guarantee.
Product questions
Before you choose.
Is 800°C the rating of every mica wire?
No. The 500°C, nickel-plated 600°C and pure-nickel 800°C versions are distinct options. Specify the intended version and confirm the complete construction.
Does a temperature value also confirm voltage or current capacity?
No. Voltage, conductor size, current, installation and exposure duration must be reviewed separately. Do not select a wire using temperature alone.
Does heat resistance prove a fire-survival certification?
No. A temperature rating does not establish a fire-survival test result. If your application requires circuit integrity during fire, specify the exact test and required duration for review.
Samples & repeat orders
Keep the specification with the order.
Define the cable
Prepare the model or drawing, operating conditions, quantity and destination. Include required documents and your requested delivery date.
Prepare a new requirement ↗Define what to check
Include the trial length and the dimensions or performance you need to evaluate. Sample availability, cost and timing are confirmed separately.
Prepare a sample request ↗Reference the approved version
Use the previous order, drawing revision or approved sample reference. State what stays the same and any changes in size, material, colour or packing.
Prepare a repeat-order request ↗Specification review
Have an existing wire to match?
Include its model, temperature variant and marking. For repeat orders, add the previous order or approved sample reference.
