Technical and economic examining of replacement ACSS high capacity conductors rather than ASCR conductors in 20kV overhead networks

Today, due to increasing energy demand, the development of urban construction is obvious. On the one hand, due to the heavy demand of consumers and increase production capacity, they need to increase their intake Demand. The growths in urban areas, electricity distribution companies are forced to increase the installed capacity to posts and distribution lines. Therefore, to increase the capacity of medium voltage overhead lines up to 20 kV voltage levels will be need to increase the conductor cross section. Most of the electricity distribution network in Iran is ASCR conductors. In order to increase the cross area, they need further mechanical calculations and changes based on end-of angles and equipment. This study compares the technical and economic capacity replacement ACSS conductors instead ASCR without changing the makeup line and just replace the conductor with higher capacity are paid. For this purpose, the MCAL software (Mechanical Calculations) made for the line mechanical calculations have been used
could help provide emergency power where it is needed. Stephen Blank of
the New York Institute of Technology wants to use aerostats,
military-grade balloons, to send hundreds of kilowatts of power over
several hundred kilometres. A laser would be sent up to the aerostat
through a fibre-optic cable, then beamed through the air to a distant
aerostat where the high-energy light is converted into electricity,
which streams back down to earth via a tether
