The European Union has recently given the go-ahead to the PVSITES project, whose aim is to make the installation of new generation photovoltaic panels easier, thus encouraging a more massive diffusion.
Increased attention to the environment and the awareness that exhaustible natural resources are exhaustible have led scholars to look for alternative sources of energy and renewable energy sources.
Nowadays, unfortunately, pollution is a problem that cannot be solved. Much is also due to the use of cars and trucks which, are extremely polluting when they travel for long distances.
The complexity of today’s electrical systems requires earth conductors. Earth conductors are fundamental for getting a job done with any problems or interruptions. However, many people underestimate this aspect.
In Italy, there are about 450 thousand photovoltaic systems, 60% of which are inefficient as a result of fraud. Some photovoltaic contracts have hidden costs or unclear clauses, proving to be real “fraudulent” contracts.
An electrical cable is nothing more than an element that contains inside a metal part used as a conductor to join two or more electrical equipment.
Just browse through our LTC catalogue to see that there are dozens and dozens of Halogen-free cables in our offer, daily requested by wholesalers all around the world. But where does their real need come from? In this article we want to make a bit of history and an analysis of the current market since, even at this time, the Research and Development department of La Triveneta Cavi is focusing on the design of new CPR Halogen Free cables to ensure more and more security in high-density people buildings.
Identifying Halogen elements
The Halogens, or elements of group 17 of the periodic table, are Fluorine (F), Chlorine (Cl), Bromine (Br), Iodine (I) and Astate (AT). Halogens react with almost all elements of the periodic table and form ionic or covalent compounds that are often used as starting materials for the synthesis of other compounds, both inorganic and organic. Among the applications there is also the production of insulating material, used in transformers and, of course, in electrical cables.
Hazard of halogen elements in cables
Halogen elements, under certain conditions, can promote the spread of a fire and the gases released may cause serious damage to health. In excessive quantities, halogens have an immunosuppressant effect and weaken people’s cognitive and coordination skills.
Historical notes on the hazardousness of halogen elements in electrical cables
According to the well-informed blog www.incore-cables.com, the key event that brought out the danger of halogen elements in power cables was the fire at Kings Cross station in London in 1987. In that catastrophe 32 people died and following investigations showed that the majority of deaths were due to the toxicity of gases and smoke, emitted by electric cables and inhaled by people, rather than to burns or open flames. That was the only time that people died in a fire in the London Tube.
Mandatory use of Halogen Free Cables
As a result of the fire at Kings Cross station, companies, cable installers and safety experts decided not to manufacture or use any more cables containing halogen elements. Soon came the obligation from the authorities that was extended not only to the London Tube and to other stations in general, but in all those buildings or infrastructure, public, private and high-density people, such as cinemas, shopping malls, hospitals, offices, etc..
Continuous development of Halogen Free cables
The obligation to install Halogen Free cables arisen after the metro accident reinforced the growing attention to safety and therefore, in the following years, La Triveneta Cavi began to produce the first LS0H (Trisecur) cables. The recent process of improving safety has seen the entry into force of the CPR Regulation (2017). Triveneta Cavi has already developed over 90 families of cables certified according to the CPR regulation and continues to develop new ones. Soon we will announce the launch of new Halogen Free cables that, completing our wide range, will add to all the others already in the catalog.
Electrical cables must be properly looked after both to ensure that they guarantee maximum efficiency and to avoid serious problems regarding the safety of each environment.
Many times, it may happen that after having done some maintenance works to your house, you find yourself with electrical cables and you don’t know what to do with them. It is exactly for this reason, that we will give you some advice on how to properly dispose of electrical cables, who you should contact and especially how to get rid of them in a sustainable and environmentally friendly way.
