Factory Direct Supply GN500 Heating Wire for Petrochemical Thermal Engineering

We've had clients in chemical plants ordering 500-meter coils of the 2.5mm² variant for pipe trace heating, and they usually want dilevery within 3 weeks or so — the 0.5mm² stuff is mostly for lab-scale setups, not industrial runs.

Pure nickel stranded conductor gives you consistent resistivity at sustained 500°C, and fiber glass double-layer (insulation plus sheath) handles short spikes up to 600°C without degradation, though you'll want to verify the actual ambient around terminations.

Rated 300/500V, it's basically a workhorse for petrochemical thermal engineering where you're wrapping reactors or maintaining viscosity in transfer lines — but don't use it where you need flexible routing below 0°C, teh glass sheath gets brittle in cold weather, that's just a fact.

CE and CCC are standard, RoHS compliance is baked in, and the earth yellow color is what most buyers go with because of that it stands out against pipe insulation — but they'll custom-dye if you're doing color-coded zones.

Available from 0.5mm² up to 70mm², and we usually stock the common sizes (1.5, 2.5, 4mm²) in coil form, but for 70mm² you're looking at custom lead times of 20 days or so.

Anyway, MOQ is typically 100 meters for standard sizes, and we'll include the COA with HPLC data on the nickel purity — just specify if you need the SDS seperately.
