TECHINCAL EXPLANATIONS FOR INSTALLATION - TECH SHEET

Our electrostatic system is based on the distribution of electrostatic impulses of brief duration tension peaks of 80 micro sec. each, over all architectural and structural elements to be protected against pigeons.

The electrostatic installations is essentially integrated by:

• A generator of impulses (excited in various forms so that it produces such impulses)
• Active electrostatic lines conducting such impulses, that are installed on every architectural element to be protected. These electrostatic lines are integrated by two conductors made of non- rusting steel (positive pole and negative pole) supported and kept distant by mini- isolators.
• Interconnection electrostatic lines that connect the installation to the generator of impulses, and series of individual active electrostatic lines. The interconnections are made through a bipolar hoop that is isolated between the two conductors towards the mass with a testing tension of 15.000 Volts standard. (maximum working tension: 7000 Volts peak)

In order to install the electrostatic lines on the architectural elements to be protected, the mini- isolators are fixed to those elements by adopting four different solutions in accordance with the cases and the possibilities of the architectural structures :

• Fixed by small expansive plugs made of lead with screws of steel AISI 316/L, that are sealed with plastic resins made of two components.
• Fixed with weld points in the case of architectural steel supports.
• Fixed in roof cornices, protected by plates of cupper, or on other structures made of non- ferrous material by ways of silver or tin welds.
• Fixed with two-component resins on sculptures, ornaments and every architectural element of high artistic value.

We will adopt for each case the most suitable technical solution with no harm for the structures.

• Even when the work is done on metallic structures, our installation is always performed with two conductors (positive and negative pole), without placing the negative one in mass on the metallic structures themselves, and then, without only placing the positive conductor. This is not a question of saving expenses or reducing the price of the installation. It is just that the only use of the positive conductor may not guarantee the safe functioning of the installation because it does not guarantee a continued electrostatic conductibility of the structures, even when these are metallic ones.
• All comments as aforementioned are applicable for works of marble or stone, because neither do these elements guarantee the conduction (even if the contrary is sustained)
• Our electrostatic conductors are made of small rounded rods of non- rusting steel AISI 316/L that guarantee absolute incorruptibility in time in the presence of the most violent atmospheric agents, whether they are acid or salty. (we mention steel AISI 316/L because a general reference like non- rusting steel is not suitable enough)
• Our mini- isolators are made of isolating material of high dielectric rigidity. They also have molecular filters impeding the polymerization and consequent weakening due to the action of ultraviolet light.
• The conductors made of the mentioned small rounded rods are not fixed to the mini - isolators by ways of screws or rigid blockades, but by means of clips, so that the possibility of slipping is guaranteed, and then internal mechanical tensions which are bound to produce harmful fractures in time, may be avoided.
• In order to strictly guarantee the electrostatic continuity of the circuits made of several series of non- rusting steel rods, these rods are put together to form the whole bipolar net of the installation by ways of hundreds of welds performed one by one on the site, using specific electrodes for steel AISI 316/L.
  We never make connections with screws or alike, despite these are of common use. The reason is that these connections, though certainly much more economical, cannot guarantee a long- lasting safety. Then, we can provide no guarantees. When considering the hundreds of connections that may integrate an installation, the failure of only one of them may affect the correct functioning of the whole installation in the future.
• Same considerations are applicable to connections between the non- rusting steel rods in electrostatic lines, and the cupper mini- conductors of interconnection cables. In this case, the problem with interconnections is even more delicate because of the delicacy of the bimetallic contact (steel- cooper). We therefore only use welds in silver paste. We never use binding screws or other kind of joints that could be unsafe, though certainly more economical.
• Mini- conductors of interconnections are isolated among them and the mass by using a 15.000 Volts tension standard.
• Following international regulations, the generator of electrostatic impulses is provided with a double isolation entry transformer (standard isolation transformer) as an absolute safety guarantee against any flaw.

Every element of the installation and every construction detail are studied and carried out so that once it is installed and subject to tension, the installation will not need of any maintenance. In this way, all expenses related to periodical maintenances are avoided, because we guarantee the correct functioning of every element of our installation, as long as no external agent damages our system.
