It's not continuous submersion above 70°C, so if your motor runs hot in a deep well, you'll need to monitor the ambient water tempearture — that pH range of 6.5 to 8.5 is pretty standard for most groundwater, but anything outside that will degrade the PVC over time.
We've had these wires running in submersible pumps for years without issues, basically because teh oxygen-free copper keeps conductivity stable and the PVC jacket holds up against moisture ingress pretty well; you're looking at single strands form Ø0.47mm up to Ø3.6mm, or multi-strand configurations like 0.80mm*7 or 1.12mm*7 depending on your winding needs.
The insulation thickness meets JB/T4014 standard, so it's not some thin-walled afterthought — we usually have stock on the common sizes, but for the 1.18mm*19 multi-strand you might want to confirm lead time (typically 2-4 weeks).
450/750V rated, though for most submersible applicaion you'll be running at the lower end of that range; it's RoHS compliant and ISO9001 certified, but don't expect it to handle aggressive chemcial environments beyond that pH sweet spot.
Also, the natural PVC color means no added pigments that could compromise the dielectric property — a detail some buyers overlook when they're just looking at price per meter.
MOQ is 100 kg per size and configuration. We can adjust for larger custom orders, but that's the baseline for stock sizes.
Yes, we include a mill test certificate showing ISO9001 and RoHS compliance for every batch. Just let us know if you need a specific format.
We can adjust insulation thickness for special applications, but it will affect lead time and price. Minimum custom order is 300 kg for non-standard specs.
Standard packaging is wooden spools or coils wrapped in plastic and placed in export-grade cartons. For humid storage, we recommend adding a desiccant pouch and storing below 30°C.
Typically 15-20 working days from order confirmation. If it's a rush job, we can do 10 days with a 10% surcharge on the total.
