NEW POWER LINE POLE SEAFTY MECHANISM
Executive Summary
This project is about building a new electric energy transmission mechanism that increases the performance of power line poles by avoiding power interruptions due to natural and human made phenomenon using a mechanism that decreases cost and ensures the safety for all living things around the power lines in comparison with the current technology.
The main goals of the project are
Preventing power interruptions in power transmission stage when accidents happen on the power lines poles caused by natural phenomenon, human made and both,
Ensuring safety of living things especially human beings in urban areas around power line poles when accidents happen on the power line poles caused by natural phenomenon, human made and both,
Decreasing the work load on the energy provider or maintenance provider by removing sense of urgency when accidents happen on the power line poles caused by natural phenomenon, human made and both which will giving the service provider more time to fix the problem,
Avoid chain reaction problems like traffic blockage which is caused by the accidents on the power lines poles due to natural phenomenon, human made and both,
Problem statement
There are many phenomenon either natural or human made that destroy public properties like power line poles and sometimes the combination of both reasons will also brig high destruction. From recent recorded phenomena that have been well known for destruction of those properties are Vehicle accident,Hurricanes and Flooding, Construction,Power line pole quality, Land slide and earth quakes And many others Whenever there is accident on the power line pole caused by natural phenomenon, human made and/ or both, it is obvious that when the pole drops to the ground from its initial erect position, all the wires which are attached to the pole will be stretched to the point of breakage or cut/ split. This is because the wires are fixed with the power line poles for the pole to carry the load of the power lines to hold the wires above the ground. When the power lines split from each other, power interruption occurs which also lead to big electrocution risk for all living things around the power lines because since the wire will be open to the environment without any coating, media like small moisture in the environment, conductive materials and others will play big role in harming peoples and animals in the electrocution accident. Aside from these problems the other major crisis it brings is the pain on the sense of urgency for the power supply company to maintain the accident with in short period of time because it will create many chain reaction problems especially if the accident has occurred in urban dense populated cities which will disrupt traffic flow, have big life risk and major power need for massive number of customers. This and other reason is an implication that indicates the level of pain it have on our economical, social and life necessity issue it brings when such accident happens.
Our solution
This project is about building a new electric energy transmission mechanism that increases the performance of power line poles by avoiding power interruptions due to natural and human made phenomenon using a mechanism that decreases cost and ensures the safety for all living things around the power lines in comparison with the current technology. This is done by manufacturing a new kind of power line pole that detaches itself from the power line wires it is carrying when accident happens on the pole that makes it lose its erect position. Meaning as seen in the following pictures, the top part of the power line has hallow conical shape and on its top surface another conical shape structure is fitted inside of its inner...

This design appears to fail to account for the need for the line to be tensioned at the poles. It also appears to lack a proper insulating structure and stand-off from the pole to ensure electrical integrity. That could merely be simplicity, for initial concept sketches, but I feel it necessary to point these out early on in your process.
Any supported cable system will have a maximum catenary length that the tensile strength of the cable would be able to support, and poles that are capable of tensioning and supporting the cable must occur at least that often. With a detachable conical insert, it appears that the failure of multiple poles would allow an intact conductor to contact the ground, making it much more difficult for utilities to remotely detect the pole failure, as well as reducing the likelihood of existing safety equipment such as reclosers to detect the fault and de-energize the conductor safely.
