Abstract
A tubular channeling unit including a grounded external metal or conductive polymer sheathing and an internal longitudinal cavity, and method for laying such a tubular channeling unit by suspension on a high voltage aerial power line system including at least two towers supporting a set of high voltage electrical conductors suspended from the towers at a specified height above the ground and at a minimum predetermined safety level.
Claims22
A transmission conduit apparatus for installation on a high voltage aerial power line system including at least two towers supporting a set of high voltage electrical conductors suspended from the towers at a specified height above the ground in excess of a minimum predetermined safety level, the transmission conduit apparatus comprising:
- a tubular channeling unit including a grounded external sheathing and an internal longitudinal cavity;
- said tubular channeling unit being attached to said at least two towers so as to be suspended in a Zone of Minimum Inductive Coupling (ZMIC) such that the difference of the distances of said tubular channeling unit to two of said electrical conductors is less than a predetermined maximum value.
A method of laying a transmission conduit apparatus by suspension on a high voltage aerial power line system including at least two towers supporting a set of high voltage electrical conductors suspended from the towers at a specified height above the ground in excess of a minimum predetermined safety level, the method of laying the transmission conduit apparatus comprising:
- providing a tubular channeling unit including a grounded external metal sheathing and an internal longitudinal cavity;
- and
- attaching said tubular channeling unit to said at least two towers so as to suspend said tubular channeling unit in a zone such that the difference of the distances of said tubular channeling unit to two of said electrical conductors is less than a certain maximum value determined as a function of a maximum allowable magnetic induction coupling between said channeling unit and said electrical conductors.
A method of laying a transmission conduit apparatus by suspension on a high voltage aerial power line system including at least two towers supporting a set of high voltage electrical conductors suspended from the towers at a specified height above the ground in excess of a minimum predetermined safety level, the method of laying the transmission conduit apparatus comprising:
- providing a tubular channeling unit including an external dielectric sheathing and an internal longitudinal cavity;
- and
- attaching said tubular channeling unit to said at least two towers so as to suspend said tubular channeling unit in a zone such that the difference of the distances of said tubular channeling unit to two of said electrical conductors which ever is less than a certain maximum value, that may be determined as a function of the maximum allowable electric field intensity on the dielectric sheathing of said channeling unit.
A method of laying a transmission conduit apparatus by suspension on a high voltage aerial power line system including at least two towers supporting a set of high voltage electrical conductors suspended from the towers at a specified height above the ground in excess of a minimum predetermined safety level, the method of laying the transmission conduit apparatus comprising:
- providing a tubular channeling unit including an external dielectric sheathing and an internal longitudinal cavity supported by a grounded element;
- and
- attaching said grounded element to said at least two towers so as to suspend said tubular channeling unit in a zone such that the difference of the distances of said grounded element to two of said electrical conductors is less than a certain maximum value determined as a function of the maximum allowable electric field intensity on the dielectric sheathing of said channeling unit.
