I would say duct tape. Duct tape has considerably stronger adhesive than electric tape. On the other hand, electric tape will stretch when put in tension when duct tape may just tear - so it depends on the type of strength you are looking for.
Electric duct tape can be used in home improvement projects for innovative purposes such as creating custom lighting fixtures, securing cables and wires discreetly, and even insulating and weatherproofing outdoor electrical connections.
To visually determine if there is enough air flow across a duct mounted electric heater, you should tape a piece of cardboard to it. A small piece that can flutter in the flow of the air. If it moves wildly, there is enough air.
Heat cannot escape the duct as easily as in open air. This results in the same amount of current causing the cable to heat to a higher temperature.
If you lay a power cable in a duct, and it overheats due to a short or overload, the smoke from the cable burning will fill the duct and be transported by the duct to places it should not be. If the cable is not balanced, i.e. not paired up with its neutral return, current in the cable will induce a current in the duct via electromagnetic induction, causing heat, loss of power, and potentially fire, even if the original circuit was operating normally. The latter effect is why penetrations for single cables in distribution panels must be slotted, so as to break the electromagnetic field.
cystic duct and the hepatic duct
The output from a utility generator is low-voltage and very high current (later stepped up to a high voltage for transmission). The high current requires very large conductors, and busbars enclosed in a bus-duct are the most practical way to accomplish this. Some generating systems also circulate coolant through the bus-duct to keep the bus bars from overheating.
It is where the water ends up that counts. It will eventually leak out of the duct and get into ceilings and may find its way to an electric panel or lighting fixture. If this happened recently run the heat to help dry out the duct and watch areas beneath where the duct runs to see if you have any seepage.

Stenson's duct
In pigs, the duct from the gallbladder is called the cystic duct, which merges with the common hepatic duct to form the common bile duct. This common bile duct then carries bile from the liver and gallbladder to the duodenum for digestion.
