To understand how the aluminium extruded
profiles have made quite inroads into the Telecoms product sector there is a
need to understand a few things about telecom products. Essentially the
telecom products can be broadly classified into four main groups they are
antennae, cabinets, radiators and peripheral equipment.
Other extruded profiles made of aluminium that are used in the telecom
industry includes Fasteners, brackets, beams, support systems. They
facilitate a quick on-site installation with minimum fuss.
Extruded Heat Sink
It is the cabinets and radiators that constitutes the largest group, and in
industrial parlance it is is known as enclosures and heat sinks. Together
they make up over 70 percent of the total sales. Aluminium extrusions in the
form of machined profiles are used for things like heat sinks and base
stations.

A primary criteria in any heat sink is that materials used for making it
must show good thermal conductivity. Aluminium alloys perfectly fits in with
the geometric structures, surface design, greater capacity of thermal
dissipation, and thin fins, the much needed features of any heat sink
product. A common aluminium alloy used for heat sinks is AlMgSi0,5 F22.
Antennas
Another application of aluminium extrusions is in the manufacturing of
antennas. There is a great challenge for the profiles here because Antennas
are subjected to varied and harsh climatic conditions The main extruded
profile forms the backbone of an antenna structure where all the vital
electronic equipment gets mounted. The image is shown of an antenna made
using profiles of extruded aluminium.
Indoor Outdoor Cabinets
Another vital item in the telecommunication equipment is the indoor and
outdoor cabinets. Increasingly OEM are opting for aluminium profiles instead
of steel because of the weight. The basic design of the system depends
whether the cabinets would be used for indoor or outdoor purposes. Generally
the profiles for outdoor purposes should be versatile enough for easy on
site installation along with being tamper and fire proof. While the criteria
for indoor cabinets is lighter extrusions so that they could double up as
rack systems, ease in production and fast assembling.
