Buried Electrical Infrastructures
Buried electrical infrastructures under the ground is a viable solution in cases in which the magnetic field (Non-ionizing radiation) projected on the radiated location, from an external source, is relatively high (and often untreatable).
A common example is an Israel Electric Corporation (IEC) Ltd. Ultra-High Voltage transmission line, installed next to a residential or office building where people are continuously present, creating a level of magnetic field that is higher than permitted by the authorized authorities (in Israel - the Ministry of Environmental Protection).
It is sometimes necessary to burry Electrical Infrastructures in the ground due to the need to reduce the magnetic level of the infrastructures’ electrical field, as well as for aesthetic or various other reasons. Electrical infrastructures buried in the ground emit less radiation to their environment as the buried conductors are very close to one another, contrary to the familiar situation with above-ground infrastructures, consisting of electrical cables located far from one another and therefore creating significantly stronger magnetic fields.
The burial of Ultra-High/Extra-High/High/Low Voltage electrical infrastructures is carried out in collaboration with the authorities and of course the Israel Electric Corporation (IEC) Ltd. and Noga - Independent System Operator Ltd. . The burial process includes a preliminary feasibility survey, an official request issued to the IEC, the opening of an order, and continuous support and supervision. Among the disadvantages of burial are its high cost and the duration of time from application until actual implementation.
