Ken,
As CraigPump is eluding to, do not attach anything including tape that may not remain where you place it.
Certain specific tapes, plastic zip ties and other sorts of implements and hardware can degrade to the point
where it no longer holds what you intended it to in place, let alone itself. Then it may fall down into your
well and cause future troubles.
Torque limiting arrestors will prevent the well string from "slapping" around in the well bore when the pump
kicks on and off and these arrestors will protect your wiring and the well string from damage.
As for the wiring, my personal viewpoint is that multi-stranded cables are best. Multi-strand cables provide
several advantages. Electrically they offer less impedance to the flow of electrical current. Mechanically they
are stronger and more resilient. Physically they are easier to handle because they are more flexible.
Solid copper wiring is used in house wiring because it is convenient, it is not expected to be subject to flexing,
vibration or physical stresses and it is not intended to carry a high capacity current over a great distance. But,
if you examine the cabling for an electric stove/range or a clothes dryer, you will find that multi-strand cable
is generally used in these applications.
The greater the distance and the higher the current/voltage, the greater the advantage of the use of multi-strand
cable. A multi-stranded cable has greater current carrying capacity than a solid wire because of how electricity
flows through the metal. It is a strange phenomena based in physics.
The electrons in motion (the electric current) tends to flow on the outside "skin" of the conductor, therefore the
more surface area you have, the greater the capacity for the conductor to carry the electric current to the load.
Electrons are all of the same charge, so they naturally repel each other like two north poles or two south poles
of a magnet would. Therefore, the electrons move as far away from each other as possible and that means that
they end up on the outer surfaces of the metal, not in the core section.
In an example, a hollow copper pipe or tube has a greater current capacity than a solid copper rod of the same
diameter. This is because the surface area of the tube has two surfaces (inside and out), nearly doubling the
total area. A solid copper rod would have only the outer surface available. The solid core of a rod would nearly
be wasted material (more appropriately it would be a non-efficient use of the material by weight and volume).
It would be impractical to fabricate an electrical conductor of hollow tubes, but if you made many small strands
of solid wire wrapped into one larger, single conductor, it would result in a more efficient current carrying device.
