Not in civilized countries as the insulated coupling will not conduct.
The labour of installing a conduit system and pulling wires is not involved. The mineral insulated and metal sheath cables can be installed directly on the surfaces of the structure to be wired and the installation is complete.
if not insulated, condensation will accumulate.
A three-phase 4-wire system has three live wires and a neutral, which is earthed at at least one point at the transformer. All current-carrying wires are insulated in this system, for safety. The voltage on the neutral might be zero or only a volt or two, but under fault conditions its voltage could be much higher.
what may happen if wires are not insulated
An earthing system is a system where circuits are connected by a ground. An insulated return system is how power is transferred to trains.

The pips in a steam heating system need to be insulated to prevent condensation. Condensation can lead to mold and or freezing of the steam pipes in the winter.

Aluminum wires are insulated.
Air insulated substation means air acts as the dielectric medium but in case of gas insulated substation SF6 is the dielectric medium. Gas insulated substations are having more advantages than air insulated substations.
