When installing an isolator switch enclosure, make sure that the terminations are tight and secure.If you are using the isolation switch to disconnect a load that must be worked on the following should be checked. Make sure that the handle of the switch is down and locked in the off position. For isolation switches that have windows in the front of them look and make sure that the switch blades are physically in the open position. Then lock the switch in the off position. Always safety first.
An air-break link (ABL) switch is designed to interrupt normal load currents (but not fault currents). In order to do so, they usually incorporate some form of very simple arc-extinguishing feature.An isolator switch, on the other hand, is not designed to interrupt current, but to isolate equipment after that equipment has been disconnected (e.g. by opening a circuit breaker).
If I'm interpreting the question accurately, a "line isolator" is an insulating standoff for transmission or distribution cable. A bus isolator is an insulating standoff for tubular or bar bus as is normally seen in a substation switching yard.
An 'isolation transformer' is a 1:1 ratio mutual transformer. It electrically isolates the secondary circuit from the primary circuit without changing the voltage level. A bathroom shaver socket uses an isolation transformer.
An isolator is just a disconnector ; it disconnects the load from the supply. The method of operating the isolator can be through a handle or through a spring or through a motor. Isolators can be on-load isolators , which can be switched off on load , or they can be off-load isolators which should not be switched off on load. A Miniature Circuit Breaker can break or open in the event of a fault. Thus its load carrying capacity is extremely high , up to 10 kiloamperes or more. What this means is that if a short circuit current to the tune of 10 kA flows through an isolator , it will melt the isolator contacts , and the damage can be irrepairable. When the same current flows through an MCB , the breaker will trip , without suffering any permanent damage. Thus an MCB is a protective device.
An SPN isolator switch is a circuit breaker; they are a device, which when used can automatically switch off the flow of electricity. They are used to protect a piece of machinery or equipment from damage by an overload of electricity.
SPN isolator stands for Single Pole Neutral isolator. It is an electrical switch that disconnects the live wire and the neutral wire of a circuit simultaneously, ensuring complete disconnection for maintenance or safety purposes. This can prevent accidental electrical shocks or disturbances while working on electrical systems.

On load switching is when a switch can be operated whilst current is still passing through the switch (i.e. it is on load) Offload switching is when a switch is operated whilst there is no current through the switch (i.e. it is offload)
TP isolator means triple Pole Isolator.
The main difference between the two is that a TP isolator is only a "triple pole" isolator. A TPN isolator is a "triple pole" and neutral isolator.

an off-load device a a switch where there is no current passing through it when its switched, a isolator is a off load device, a light switch is a on-load device because there is current passing through it when its switched.

The Oscillation Isolator was created in 2018. It is a device designed to reduce vibrations in mechanical systems.
