What is high voltage.
High Voltage is the electrical voltage between the power lines exceeding 1000 volts or more.
Why use high voltage
Power system with high voltage electricity can be sent to a distance. And the loss of electrical power system under a low voltage. The power transmission efficiency. Must be delivered with high voltage almost all
High voltage is dangerous, however.
Because high voltage is the voltage very high compared with the low voltage. With common household appliances (220 volts), high voltage is able to jump over the air. Or insulators have approached the object or creature. Without touching or touching wires. If the object is within a high voltage dangers that can jump over it. This will depend on the risk level of the voltage of the high voltage By the high-voltage electricity can jump across the stage, it is extremely remote. High voltage is dangerous genie. The statistics have been danger of high voltage in the service of the MEA. Deaths per year, nearly 100 injured and disabled people.
We do know that it is a high-voltage power lines.
Due to high voltage power lines is dangerous to jump over, so they have to hold the power cord. With an insulating material. To some extent with the high voltage. Insulators used mainly to do with ceramic floors. Hand shaped like an inverted bowl called insulators. Therefore, we can observe that the high voltage power lines. From the power line insulators with layers. The Class of insulators. To indicate the voltage level of the high voltage. Observing that the high voltage Another is. The height of the power cord. High voltage power lines. Usually elevation of 9 meters above the ground from the power lines above. Usually the voltage over the power lines below.
High voltage power lines are insulated or not.
High voltage power lines, most of the electricity used by road or field. Most are not insulated, or if there is insulated cover only some of which are considered unsafe to touch or touch. Insulation shall be secured with thick insulation. Are overlain by a thousand Shield (Shield) and a shell on top. The cable is heavy so it can not lean on the power poles are not.
