HRWHeat-Resistant Wires

Silica-glass-yarn braided Nickel-conductor Wire: NI-MS500

Compliant with RoHS2
Max. operating temp:500℃
Rated voltage:600V

Nl-MS500 is a super heat-resistant wire, the conductors of which are heat-resistant and corrosion-resistant nickel-conductor wire wrapped in glass-mica tape coated with silica-glass fiber. High-performance coating, which is light yellow and excels in insulating characteristics, is applied to the insulation of NI-MS500.

Features of nickel-conductor wire

Nickel-conductor wire is strongly resistant to corrosion as well as heat, does not greatly deteriorate with age, and achieves satisfactory machine performance.

Features of Nl-MS500 series products

The maximum operating temperature is 500℃, and the rated voltage is 600V!
Nl-MS500 series products are superior in insulating characteristics and heat resistance to TM450 series products.

Applications

Nl-MS500 series products are used for applications such as the lead wire in an electric heater, which must be highly resistant to heat as well as corrosion, and wire in high-temperature equipment.

*Since Nl-MS500 series products have hygroscopicity, their insulating characteristics differ depending on the atmosphere in which each of them is routed. Therefore, avoid using NI-MS500 series products in humid or wet places. Please feel free to contact our Sales Department for custom-made products not listed above.
