FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

Why does PE2-PA use both Polyethylene (PE2) and Polyamide (PA) instead of a single PVC or PE layer?
PVC absorbs water over time and has higher dielectric losses, while pure Polyethylene (PE2) has outstanding water-immersed electrical insulation (> 10,000 MΩ·km) but is relatively soft and easily nicked when coils are pulled through sharp laminated steel stator slots. Co-extruding a thin, hard Polyamide (Nylon) outer skin over the PE2 core combines polyethylene's electrical perfection in water with nylon's tough, low-friction mechanical gliding surface.
Why are intermediate copper diameters (like 1.65 mm, 1.85 mm, 2.10 mm) so important when rewinding a submersible motor?
Submersible borehole motors have long, narrow stator cores with fixed slot cross-sections. If a rewind shop substitutes a wire that is even 0.10 mm too thick, the required number of turns will not fit into the slot; if it is too thin, copper resistance increases and motor efficiency drops. Stocking fine 0.05/0.10 mm DIN 46399 diameter steps guarantees an exact OEM match.
When should I choose XLPE-PA (+90 °C) instead of standard PE2-PA (+70 °C)?
Standard thermoplastic PE2-PA is rated for +70 °C maximum winding temperature in cool borehole water. Specify cross-linked XLPE-PA (+90 °C) when the submersible pump operates in warm geothermal/industrial wells (> +35 °C ambient water), is driven by a Variable Frequency Drive (VFD), or experiences frequent start/stop thermal spikes.
How should PE2-PA coil leads be spliced to the flat EPDM drop cable inside the motor?
Because Polyethylene is non-polar, ordinary electrical tape will not seal underwater. Strip the outer PA and PE2 layers in a stepped pencil taper, crimp the copper conductor, wrap tightly with self-amalgamating EPR/butyl splicing tape that bonds to the cleaned PE2 core, and over-wrap with protective vinyl/rubber armour tape.
