Wooden pole
تير برق چوبي
Hang: /hæŋ/
The simple structure consists of a wooden pole having more than one arm. The arms are used for hanging the wires.

OHTL contains 3 important components, Insulators, towers, and conductors

Insulator: /ˈɪn səˌleɪ tər, ˈɪns yə-/
Insulators get dirty due to environmental pollution and dusty weather. Visual inspection could be done without power isolation because you could inspect them from a safe distance.

Flash-over:
In electric power transmission, a flashover is an unintended high voltage electric discharge over or around an insulator, or sparking between two or more adjacent conductors. A flashover is an electric discharge over or around the surface of an insulator.
As you know dirty insulators may pass electrical current as a flash-over
تخليه الكتريكي
The cleaning insulators process takes two forms. One is by direct contact with it and using a piece of dry and smooth clothing, in this case, power must be isolated.
Precaution: /prɪˈkɔ ʃən/
Insulator replacement could be done without power isolation but, with great precautions and special isolated tools.

Aging: /eɪdʒing/
Due to aging and windy weather besides short circuits and lightning strikes the overhead power line conductors are cut.

Splice: /splaɪs/
we used splicing device to connect a cut OHTL wire, and we found the splice itself broken during visual inspection.
