This new pole is made up of tapering steel sections which can be packed inside one another for transport
(twenty 35-ft. poles can go on a 30-cwt. truck with no overhang) and which are laid out loosely on the site
and strained together by a tightening wire, hangers and cross-arms being added where necessary. Elliptical sections
are used to reduce wind resistance, the major axis being at right angles to the run of the power line. - Advert 1938
16 different designs were available in 1938. - Advert 1938
The Adastra Pole is manufactured from high quality steel, and built up of tapered
elliptical or circular sections. The sections overlap when assembled, and are drawn tightly
together by means of cable and winch straining gear, thus forming a strong friction joint.
When nested, the sections occupy a minimum of space. Transport charges are accordingly greatly
reduced and portability much facilited. The cross-arms and brackets have tapered sleeves.
Erection is very simple, reducing labour costs to an absolute minimum. By virtue of its design
and the protection afforded by galvanising, maintenance costs are negligible. Precast stone
bases of very attractive design can be supplied if ornamentation is considered desirable
and for abnormal soil conditions a concrete plinth may be cast round the pole in-situ - APLE Conference Programme 1939
The firm mention that they have made efforts to achieve the ideas put forward by the Royal Arts Commission
which were simplicity, efficiency and refinement - but they don't actually state that their designs were approved! Columns
were manufactured from tapered hexagonal, elliptical or circular sections. The sections overlap
when assembled and are drawn together using straining gear, thus forming a strong friction joint. Sections only
occupy a small space during transportation, aiding costs. Cross arms and brackets have tapered sleeves. There is
accommodation in the base for auxiliary apparatus such as chokes, condensers etc. Cast bases of attractive design can
be supplied if desired. - APLE Conference Programme 1945
The "Adastra" construction and finish has been used throughout the war by all three Services as the standard
equipment for aerial masts. - Public Lighting #38, 1945
In addition to small-scale models, there is a display of photographs of 16 standard type of column suitable for Group "A" and Group "B"
lighting and for supporting ornamental lanterns. Components such as standard bracket arms in galvanized steel and spigot adaptors in cast
aluminium alloy will be on view, together with a ful sized base section with inspection door and detachable slotted steel instrumental pabel
fixed inside the column. Galvanized stel had withstood the rigours of the war-years without noticeable corrosion effects,
fully justifying the foresight of those engineers who had installed Adastra. columns. Special
mention has been made in the saving of maintenance cost effected by the use of these columns. The pleasing
appearance of the column is expressed in the perfect proportion of taper and elimination
of superfluous ornamentation. Two types of column are produced: Circular and Hexagonal. - APLE Conference Programme 1946
Standards of a design pleasing in appearance, strong yet light in weight, with an assurance of lasting protection
in the finish provided by hot spelter galvanising. These features combined, produce a column durable in service,
easy to erect, economical to maintain, and low in first cost. The columns are assembled from tapering steel sections
of circular or hexagonal form. The sections overlap in assembly, forming a strong friction joint. For storage or transport the
sections are nested one inside another, and complete column occupies only the space of its largest section. Two
classes of column are produced: Hexagonal and Circular. Both classes cover the 25ft. and 15ft. mounting heights.
The standard outreaches of the tapering bracket are 3ft. 0in., 4ft. 6in. and 6ft. 0in. for 25ft. mounting height. Tubular
arms braced by tie rods are recommended for outreaches above 6ft. 0in. All columns can be equipped with inspection
doors and an adjustable slotted steel instrument panel suitable for the accommodation of gaseous discharge lighting
auxiliaries and control apparatus inside the base section. Small fittings, including spigot adaptors, finials and
base collars have been redesigned to utilise a light alloy for their production, resulting in a considerable reduction
in weight. A concrete base plinth is easily csat onto the columns at ground level, steel shuttering in sizes
to suit the various types is supplied specially for this purpose. - APLE Conference Programme 1947
Columns were available in elliptical, hexagonal and circular cross-sections. By 1947, only the hexagonal and circular
versions were being exhibited. The columns were equipped with inspection doors and an adjustable slotted steel instrument panel suitable for the
accommodation of gaseous discharge lighting auxiliaries and control apparatus is fitted inside the the base section.
Small fittings, including spigot adaptors, finials and base collars have been redesigned to utilise a light alloy for their production,
resulting in a considerable reduction in weight. - Public Lighting #47
