General information
1.1 - Field of investigation and object
Through this document, the entire tile manufacturing process is examined.
Due to the complex nature of the manufacturing process, few companies own all the elements that
make up the chain. Companies tend mainly to focus their investment on one part of the process.

General information
1.2 - General information about tile making factories
There are 3 main stages in tile manufacturing:
i Basic material production, from raw materials to clay powder.
i Preparation of enamels (not dealt with in this document).
i Manufacturing of tiles into finished products.
Clay powder production
At this stage, different clays are ground, mixed with water, processed and then pulverised to make
them into a homogeneous powder.
Cycle:
1 - The clay is delivered and stored
2 - The raw materials are sampled, dosed and weighed
3 - The clay is loaded and ground
4 - The clay is mixed with water (slip)
5 - The slip is pulverised and dried (homogeneous powder)
The high consumption process, requires a significant daily supply of
energy. Some companies use electrical co-generators to make their
installation cost-effective by reselling kiloWatt hours to electric utilities.
Making tiles into finished products
The powder, stored in silos, is sieved and taken to hydraulic presses weighing between 1600 and
2500 tons that provide pressure of up to 450 kg/cm2.
Tiles with a 5% water content pass through a high temperature oven (200°c), for around 6 s so that
afterwards their water content is only 0.2%. In order for the oven to operate continuously, a
compensator is included in the run, thus allowing the flow to be regulated.
The dried products are then directed to the enamelling and silk-screen printing run. Monitoring at
the end of each stage ensures the perfect quality of the product.
The enamelling run consists of several interchangeable modules arranged according to demand. A
module consists of a control cabinet and a unit with a programmable logic controller that ensures
the monitoring, regulation and control of the variators. The cleaning, trimming, enamelling, monitoring
and silk-screen printing stages are set up over a distance of around 160 m. In order to ensure a
continual flow, compensator-regulators are inserted along the run.
At the end of the run, storing is carried out using trolleys guided by programmable logic controllers,
allowing continual management of the taking of tiles to the oven and baking. To ensure that the tiles
are perfectly baked, an oven, about 120 m long, is used at a temperature of 1000°c.
Cycle
6 - The clay powder is
extracted from
the silos.
7 - The tiles are
moulded.
8 - The tiles are
routed along the
enamelling run.
9 - The enamel is
prepared and
injected.

General information
1.3 - Overall layout of a tile making factory
The clay powder production area
Its area is 2000 m2, with a height of up to 30 m. The distinctive feature of this area is its high dust
level.
Due to the significant height of these sites, lighting is provided using high power projectors. The
lighting used for the enamelling run is provided using 400W bulbs.
The enamelling run
Its floor space varies between 10,000 and 80,000 m2. Average production is around 1m2 of tiles per
1m2 of floor space.
It can be estimated that, for an average floor space of 10,000 m2, 10,000 m2 of tiles are produced per
day.
The use of high pressure water to clean the machines is additional stress on the electrical equipment.

Customer requirements
2.1 - General requirements
2.1.1 - Continuity of operation
One of the technical requirements for this type of factory is continuity of supply. A break in the power
supply leads to significant financial losses. Even a short break can cause a halt in production at the
sensitive areas in the chain which are:
The ovens
A break in the current leads to the tripping of the solenoid valves, which stop the burners. Since they
have to be manually reset, which can take several minutes, this can cause a drop in oven temperature.
The cooling of the oven leads to large scale operations that are a source of production losses. The
tiles that experience a fall in temperature during their 45 min. route become either concave or convex,
causing a jam at the oven rollers.
The intervention is conducted in three stages:
i the oven is completely cooled
i the jam inside the oven is manually cleared
i the burners are set into operation and the temperature stabilised
In order to avoid these consequences, the oven’s electrical supply needs to be precisely managed.
This consists of adding an electrical generator as an auxiliary power source and the thorough
monitoring of the primary source. In order to avoid short breaks, the primary and auxiliary sources
are synchronised at critical times.
The enamelling run
There are many consequences of a break in the power supply. Among the most significant are:
i stabilisation of the enamel coating, an extremely precise process that takes into account viscosity,
speed and product uniformity.
i flow continuity to avoid shut down of the oven and cleaning the production line after a prolonged
halt.
i setting of the automatic devices. In general, there are around 30 programmable logic controllers
per run.
Not to mention the consequences of an operating loss related to the clay powder production process
and which are similar to the financial losses of heavy industries, such as the iron and steel or glass
industries.
2.1.2 - Development
Due to their size, investments are made progressively. Extensions are made according to market
demand, for both heavy industry and enamelling runs. The increase in production capacity leads to
the addition of equipment.
In general, the site’s infrastructure is built for a given capacity, with areas for future extensions, of
which the majority are:
i addition of a mill
i addition of an enamelling run
2.1.3 - Ease of installation linked to design
Adapting to market demand in a competitive context implies a high degree of reactivity. This means
looking for time savings, ease of installation and maintenance solutions.
Investors regard design as a differentiating value and proof of quality.

2.2 - Electrical specificity
Electrical specificity
General needs are broken down into specific requirements for the site as a whole. The electrical
aspect is also concerned by this requirement. The busbar trunking system is being used more and
more in order to better satisfy these technical constraints.
- When implementing the project
Although the power of the machines is known in advance, the exact layout is never known in
advance.
The products are progressively integrated into the architecture of the building, and care is taken
to respect deadlines and control costs.
There are often last minute changes, mainly due to the complex nature of the metallic structure
supporting the machines.
The busbar trunking system solution offers a good integration into the architecture of the building,
made even easier thanks to its extremely low space requirements.
- During operation
Continuity of supply is an essential factor in the choice of the electrical distribution type, for the
same reason as its ease of adaptation to extensions.
The versatility of the modules in an enamelling run’s design is an additional technical constraint
when choosing a solution.
Installation convenience linked to rapid mounting time for run extensions or modifications is
a technical-financial condition that can be a deciding factor in the technological choice of electrical
distribution.
The solutions that fulfil these technical requirements will be studied at a later date with regard to the
advantages of distribution using the busbar trunking system.
Power requirements
Energy requirements depend on production capacity, which develops over time and leads to the
use of new machines and new runs.
The system’s power load is broken down according to the following configuration:
i Clay processing area, from 3x1600 kVA to 6x1600 kVA
i Enamelling run, from 1000 kVA to 2000 kVA
In order to ensure continuity of supply of the sensitive areas, the installation is fitted with generating
sets: a main 200 kW set for the general supply of the enamelling run and a small set of around 50
kW for each oven.

2.3 - Architecture
General information
Medium Voltage power from the public distribution network is used to supply production sites.
Bearing in mind the amount of power consumed, these producers generate surplus electricity thanks
to the use of co-generators, which allow the steam used in the clay powder production process to be
recycled. This surplus is then sold to electric utilities. In this way, they reduce the kWh price to a
minimum.
In general, several transformer substations are used for the low voltage distribution of a single site.
In order to adapt to production variations, a bypass system is built between the transformers, thus
allowing the distribution of power to be regulated.
Particularly in the enamelling zone, there are generating sets in parallel with the transformers, thus
allowing breaks in electrical supply to be managed. A capacitor bank allows the sensitive area of the
oven to be supplied and thus allows uninterrupted operation to be guaranteed.

i Enamelling run area
A generating set is added in parallel to the main circuit to ensure continuity of supply at the main
circuit level, i.e. the oven and the enamelling run. The automatic source reversing switch located at
the main switchboard level carries out the changeover and ensures the automatic load restoration of
the main points.
In the event of a break in the current, a lower powered generator ensures the stand-alone supply of
the oven. Moreover, UPS and a capacitor bank are used to avoid breaks at the vital points, i.e. the
burners’ solenoid valves.

Electrical distribution
3.1 - Electrical distribution using the busbar trunking system
General standards
The busbar trunking system complies with all the rules stated in standard IEC 439-1 and 2.
Certain electrical properties must be known for the different phases:
i average ohmic resistance per metre
i average reactance per metre
i impedance per metre
The busbar trunkings must be designed to bear mechanical loads.
The whole of the trunking, including its tap-off points, must be designed in such a way as to prevent
indirect contact as well as incorrect connections with the live parts.
The overheating limits of the casing and the conductors at the most sensitive areas are precisely
defined.
Together, these criteria ensure a safe and reliable electrical distribution for an economical solution
for the operation. Decentralised distribution using the “Canalis” busbar trunking system completely
fulfils the requirements regarding:
i safety of equipment and people
i continuity of supply
i reliability
i ease of maintenance
Specific performances
An upgradable installation
The constraints of progressive investment are perfectly controlled with the Busbar trunking system
solution, which allows lengths along the run to be interchanged, added and recovered. The factorybuilt tap-offs guarantee flexibility to upgrade the installation. The modular nature of the lengths
allows all or part of the installation to be reused.
Price and quality suitability
More than 30 years of expertise and a product design that guarantees the safety of people and
equipment contribute towards obtaining an installation, the economic performance of which is
favourable compared with the other solutions. A well-established production tool together with lengths
that are easy and safe to mount guarantee a time saving and control over unforseen work site
problems.
Reduced space requirements
The compact nature of the trunking allows the space requirements to be reduced by 2 to 6 times in
comparison with a traditional solution. Changes in direction are made at right angles.
Good protection in the event of fire
High power distribution trunkings are guaranteed against the propagation of toxic gases (IEC 754)
and thick smoke (IEC 1034). The insulating materials used are halogen-free and self-extinguishing
(IEC 695.2.1).
The minimum fire withstand is 2 hours, in accordance with ISO 834.
Very good degree of protection
The basic degree of protection is IP 52, with an anticorrosion treatment allowing installations to be
built in demanding environments.

6 - A fixing device provides the trunking with support every three metres at most on a horizontal run. For floor
distribution, a special bracket is needed for each level.
7 - A variety of lengths that can be specially fitted, such as the straight length, elbow or tee, make it easier to adapt
to the constraints imposed by the site.
8 - The cover of units fitted with a circuit breaker or switch can only be opened when they are in the “OFF” position.
When the door is open, the degree of protection is at least IP 2 (protected against finger contact).
The live removable tap-off units have the following properties:
-The plug-in/withdrawal operation requires prior isolation either by the cover (using a tool) or by putting
the apparatus in the ”OFF” position.
- Protective earth (PE) continuity between the unit and the trunking is established first, before that of the live
conductors and inside the trunking.
- The contact bracket of the protective earth conductor opens the shutter at the tap-off point and polarises both.
- At the tap-off point, the contacts are made silver to silver or copper to silver.
