System and method for monitoring the condition of electricity conductor support systems, i.e. towers, in a power network distribution system employing a tower structure integrity sensor assemblage. The system allows for identifying particular portions of a structural system for maintenance attention. The tower sensors allow identification of structural failures of electricity transmission towers.

A full-moment column collar is disclosed, including four collar flange components and four collar corner components. Each collar flange component includes an upper transverse element and a lower transverse element, connected by a bridging member. Each collar corner component includes first and second expanses defining a corner and a standoff portion extending from the corner, the standoff portion having a distal T-shaped structure. Each collar corner component is configured to connect two adjacent collar flange components, and each collar corner component has a multi-axis alignment structure extending from a bottom end portion for vertically positioning a lower transverse element of a respective collar flange component.

A node structure (12, 14) for connecting two or more convergent members (16, 26) of a lattice frame to each other and to one or more other members of the lattice frame. The node structure (12, 14) comprises a pair of opposed spaced-apart faces (30) that are substantially planar and substantially parallel to each other. At least one pair of root formations (32) with respective central longitudinal axes define an interior angle between them, those axes diverging outwardly for alignment with respective members of the lattice frame and converging inwardly between the faces (30). An inner connecting wall (34) between the root formations (32) of the pair connects concave-curved inner edges (36) of the faces and extends in a concave curve around the interior angle to join the root formations (32) of that pair.

A tower (1) having equipment (3) mounted thereon is disclosed. The tower (1) has an ice shield assembly (2) for protection to of the equipment (3) against falling ice mounted thereon. The ice shield assembly (2) comprises a tower fixture arrangement (5) being secured to the tower (1) and an ice shield (4) connected 5 to the tower fixture arrangement (5) via a hinge (6). The ice shield (4) is configured for vertically overlapping the horizontal extends of the equipment (3). The ice shield assembly (2) further comprises at least one spring element (7), e.g. in the form of a curved rod, connected at one end to the ice shield (4) and at an opposite end to the tower (1), the at least one spring element (7) 10 being configured to allow the ice shield (4) to pivot relative to the tower (1) at the hinge (6) in order to ensure a gradual transfer of energy from falling ice, which collides with the ice shield (4).

A column with at least one photovoltaic element for converting radiation energy is disclosed. The at least one photovoltaic element converts radiation energy of light, such as sunlight, into electrical energy. The at least one photovoltaic element is arranged on the column, and at least one photovoltaic element is a flexible photovoltaic element.

Provided is a tower of a wind turbine, having a hollow inner space and a door for opening and closing an aperture into the inner space, wherein the door is a sliding door, which is slidingly arranged on a tower aperture member attached to the tower, and which sliding door is at least partially sealed by a seal to the tower aperture member at least when the door is in the closed position.

This disclosure relates to pole bases, specifically to light pole base cabinets that can house items. The pole base cabinets can be positioned between a light pole and a footing. The pole base cabinets provide a base to a light pole while adding additional functionality. The cabinets can include a main opening allowing access to a cavity in which items can be stored. Access to the cavity can be restricted with a door that uncovers and covers the main opening. The pole base cabinets can include support panels, internal stiffening panels, external stiffening panels, support tabs, flanges, tabs, a peripheral wall, and other features to provide structural support and enclose the contents in the pole base cabinet.

A pole for supporting at least one device thereon, the pole comprising: a post to support weight of the pole and to attach the at least one device thereto; and at least one cover at least partially covering at least one side of the post, the post and the at least one cover together defining at least part of a longitudinal channel in the pole to house the at least one device attached to the post; wherein an edge of the cover is in pivotable engagement with the post to allow access to the post in the longitudinal channel.

A pole cover assembly and a method for mounting the assembly onto a pole. The assembly includes a pole cover that has a first portion with a first longitudinal end. A base portion extends from the first portion and the base portion has a base portion depth and an inside diameter that is greater than an outside diameter of the first portion to accommodate a first longitudinal end of an adjacent pole cover therein and define a circumferential clearance gap around the adjacent pole cover. A longitudinal slit runs a length of the pole cover and separates axially extending arc segments of the pole cover. The arc segments overlap one another when disposed on the pole.

A stealth pole includes a plurality of canister sections, each of the plurality of canister sections including a spine, a first splice plate located on a first end of the spine, a second splice plate located on a second end of the spine, and a canister cover that covers the spine, the first splice plate and the second splice plate. A method for reinforcing the stealth pole includes removing the canister cover from at least one of the plurality of canister sections; attaching a plurality of stiffener members to the first splice plate and the second splice plate; and applying tension, compression or a combination thereof to the plurality of stiffener members. The plurality of stiffener members reinforce the spine of the canister section. A reinforced stealth pole is also described.
