A street lighting pole including at least one upright outer wall portion defining an enclosed space of the street lighting pole; a substantially vertically arranged divider (11) dividing at least part of the enclosed space into at least two substantially vertically arranged bays, the at least two bays including a first bay and a second bay; a space air inlet into the enclosed space arranged at a bottom of the upright outer wall portion; a space air outlet from the enclosed space arranged at a top of the upright outer wall portion; a respective individual air inlet for each of the at least two bays arranged at the bottom of the divider; and a respective individual air outlet for each of the at least two bays arranged at the top of the divider. The respective at least two individual air inlets and the respective at least two individual air outlets provide separate air flows in each of the at least two bays for cooling thereof, allowing to individually control the climate in each of the at least two bays of the street lighting pole.

The present invention relates to a modular system of construction, conduction and fixation of tubular structure elements, comprising a first module (200), a second module (300) and, optionally, one or more additional modules (n), wherein each module (200, 300, n) comprises, in the region of its upper end, an annular fixing flange (230, 330) and crimp fins (240, 340) arranged inside the upper end at a fin distance (P.sub.240) which is equivalent to a crimping depth (P.sub.200, P.sub.300) decreased from 10 to 100 millimeters, preferably from 50 millimeters. The crimping depth (P.sub.200, P.sub.300), in turn, corresponds to a value between 0.5 and 3, preferably 1.5, times the diameter measurement (D.sub.200, D.sub.300) of the corresponding module (200, 300). The present invention also relates to a corresponding tubular structure (150).

The present invention discloses a prestressed-bolted dry-assembled segmental precast hybrid tower with grouting-free, comprising a top steel tower tube, a reverse self-balancing steal-concrete transition section, and a prestressed-bolted dry-assembled segmental precast concrete tower with grouting-free dry fast splicing and a gear reinforced wind turbine foundation; the steel tower tube, the steel-concrete transition section, the concrete tower tube and the hollow wind turbine foundation are integrally connected from top to bottom through a prestressed steel strand system to improve the overall bending resistance of the tower; the upper end of the prestressed steel strands is anchored to the steel-concrete transition section, and the lower end is anchored to the bottom face of the wind turbine foundation corbel; the concrete tower tube is composed of a number of segmental tapered precast concrete tower segments, which are grouting free spliced vertically, and the vertical splicing utilizes positioning pins to accurately position the installation position. The prefabricated concrete tower tube segment is formed by a number of circular arc-shaped prefabricated concrete pipe segments with circumferential grouting free dry splicing. The segments are spliced into a whole by prestressed bolts and then installed staggered from top to bottom to enhance the shear resistance.

A modular, space-efficient support structure mounts multiple electrical devices. The structure is modular to allow for subsequent addition and removal of electrical devices by adding and removing primary structural elements coupled for structural efficiency. The structure is deployable in many locations without reconfiguration and has reduced dependence on local site conditions. The structure uses non-permanent construction methods to facilitate rapid assembly, disassembly, re-deployment and re-use of components. Multiple electrical devices such as transformers are mounted at elevation on device mounting columns. The electrical devices are interconnected to each other in parallel or series with connectors mounted on the top portion of the device to allow maintenance clearance underneath. The arrangement of the electrical devices maximizes the density of the devices while maintaining vertical, lateral and radial safety clearances. The electrical devices are arranged in a symmetrical fashion around the primary structural element for symmetrical load distribution.
