around $500 a pole and $2 a foot about $1000 for the pole mounted transformer poles need to be less than 100' apart
In 120/208V 3 phase system you have 5 wires: three hots, one neutral, and one ground. You have 208V between any two hots and 120V between any hot and neutral. The neutral is the same as in a single phase system. Clarification: Only 4 wires maximum come from the pole - 3 phases and a neutral, and then only if the transformers are on the pole. The ground is always locally derived from a ground rod(s) and/or cold water pipe ground. Most of the time, only 3 wires come in from the pole - the 3 phases in a Delta configuration (Delta has no neutral). The neutral is then derived from a local transformer connected in a Delta-Wye setup. The neutral is the center connection in the Wye. So, from the utility feeder to the transformer - 3 wires. From the transformer (wherever it is located) to the building service entrance panel - 4 wires. The ground is connected at the service entrance panel, and from there to the rest of the building you would have all 5 wires. Clear? In the US, 208/120 is a standardized mains voltage, but in some parts of the world, the phase-to-phase voltage is 220. In that case, the phase-to-neutral potential (in a 3-phase system) would be 127 Volts, not 120.
It is a type of transformer that you usually see hanging from a utility pole that feeds your house. It transforms the high transmission voltage down to the usable voltage that is used in the home.
A double pole switch can be used in either a 240V application where you'll need to disconnect 2 "hot" lines, or it is useful when switching a light from 3 different switches. Disadvantage? I suppose it could be a little confusing to face all those contacts on a double pole switch.
A single pole circuit breaker can protect one hot wire to a given load where as a two pole circuit breaker can protect two hot wires to a given load. In the North American system this would equate to 120 volts on a single pole circuit breaker and 240 volts on a two pole circuit breaker.
The transformer steps down the voltage from 600kilo volts which is what is at the power pole/lines to multiple strands of 120v or hot wires which is what your house runs off of.
To hang a pole transformer from a pole, you will need mounting brackets designed for transformers. The brackets should be securely bolted to the pole at the correct height to ensure proper installation and safety. The transformer can then be lifted and attached to the brackets using appropriate tools and safety measures.
Yes, you can change a single pole switch to a double pole switch for your winch. A double pole switch will have two input wires (live and neutral) and two output wires to control the winch operation. Make sure to follow proper wiring and safety guidelines when making the switch to ensure the correct function.

a step down transformer is used to lower the voltage from the powerlines into your home. a common slang term for this type of transformer is a pole pig.
You can install a 220V single-phase transformer to step down the 440V three-phase supply to a 220V single-phase output. Connect the transformer's primary winding to the 440V three-phase source using the three poles and four wires. Then, connect the secondary winding to your 220V single-phase load using the two poles and three wires. Make sure to follow local electrical codes and regulations when performing this setup.
Lower the rating of the primary fuse feeding the transformer.
it is nere the pole
240 volts from the secondary side of the transformer to your house
If you are referring to a pole-mounted distribution transformer, it's in order to maintain a safe clearance between its high-voltage connections and ground level.
