The presence of pipes without seals can lead to the propagation of the explosion and, with it, the increase in pressure from the initial equipment to those connected to it. The regulation offers us a series of tools to limit the occurrence of pressure-piling phenomena, for example by sealing the exits of the enclosures, and by limiting the occupation of the sections inside them.
What are the fundamental lighting quantities that the designer of a lighting system must deal with?
To save energy in lighting systems located in areas at risk of potentially explosive atmospheres, it is possible to decide to intervene by automatically switching off the devices after a certain number of hours or, where possible, by reducing the luminous flux at the outlet thanks to the use of floodlights, linear lighting fixtures and high bays with several types of dimming.

Cost- effective device solutions are increasingly widespread. In addition to the economic advantages, limited breathing devices can also boast improved performances such as less weight, better luminous efficiency, higher heat dissipation.
In intrinsically safe systems, associated equipment plays a key role in the safety of the system. Their positioning can be foreseen outside the hazardous area or, alternatively, in explosion-proof enclosures that can provide them with adequate protection for installation in Zone 1.
They replace the PY-SPY, FSQC – FP and EPC/EPRC – AP series
In an intrinsically safe electrical system, the electrical devices that can be installed in the hazardous area can be simple constructions or constructions certified as intrinsically safe. The first can be passive components, components with well-defined stored energy or with limited energy generation. The latter are more complex ...

In installations with areas classified as being at risk of explosive atmospheres, the 'Ex i' is the protection mode with the most certificates active on the IECEx website. The intrinsically safe method of protection is based on the principle of eliminating the ignition by limiting the energy in the danger zone.
Group IIB, Group IIB+H2 and Group IIIC
Suitable for inserting only circular armored cables into 'Ex db' enclosures with threaded entries and 'Ex eb' or 'Ex tb' enclosures with threaded or flat entries.
Cold flow in cables is the movement of the cable sheath/filler under compressive forces created by moving gaskets in the cable glands, where the compressive force applied by the gasket is greater than the resistance of the cable sheath/filler to deformation.
The mechanical protection system protects guarantees resistance against shocks with an impact energy of up to 20 J
Combined protection methods represent a fundamental approach to guarantee the safety of electrical equipment in areas classified for the presence of potentially explosive atmospheres. Their application makes it possible to satisfy different construction and operational needs, combining the advantages of the various protection methods available.

Metallic materials are not subject to the typical problems of plastic materials such as aging and resistance to UV rays, but rather can become ignition sources themselves. This is why the legislation pays particular attention to the parts that act as housing.
The main materials of non-metallic origin in electrical equipment are plastic and elastomeric materials. Their enemies are aging, ultraviolet rays and electrostatic charges

Street lighting in areas at risk of explosion must minimize glare phenomena and have a luminous footprint on the ground characterized by homogeneous illumination without large peaks and shadow areas. To obtain a better result, the light emitted must have a greater luminous intensity on the sides rather than on the symmetry plane of the device. With the advent of LED technology this need is met by the use of so-called "secondary optics".

In this article, we will delve into the connection of 'Ex db' and 'Ex eb' electric motors with 'Ex eb' junction boxes to the power line using electrical connection accessories, i.e. adapters, sealing fittings, cable glands and flexible tubes. Being able to use an Ex-eb cable gland is not at all negligible from an economic point of view. The time saving during installation compared to installing a sealing fitting or an Ex-db cable gland is considerable.
Increased safety electric motors or flameproof electric motors with increased safety connection box have been on the market for many years. Let's see the connection of Ex- db electric motors with Ex- db connection box to the power line by using some examples of system applications

In the design and use of electrical devices we must manage conductive parts with different electrical potential, with even very high voltage differences. The risk of formation of electric arcs in the air and creeping currents on the surface of the insulation material must be considered. To limit these phenomena, during the design phase we intervene on the distances between exposed conductive parts.
There are a series of physical phenomena which concern all electrical devices in general, but which assume great importance in equipment for areas classified as hazardous for potentially explosive atmospheres. One of these phenomena is called "breathing".

The components used in contexts at risk of forming an explosive atmosphere are made with particular materials. This is particularly true in the case of plastic materials. In contexts designed to form insulation between conductors, the materials used are selected from among those that express better tracking resistance.
Explosion protection is often a forced choice. It is, in fact, the legislation that requires the application of certain protection standards that are often little known. Cortem focuses on informing and training its customers.
Among the equipment suitable for use in explosive atmospheres with an EPL Gb, those with increased safety are undoubtedly the most similar to an industrial standard product. Over the years this method of protection has spread in junction boxes and in particular in lighting. In general, the lighter and more portable constructions of the increased safety products have been appreciated by plant engineers.

Often the meaning of the supplementary letter is little known, misunderstood and misinterpreted. Not understanding the difference between component and equipment or thinking that a certificate with the final "X" is a sort of B-series certificate with strong limitations on the use of the equipment is completely anachronistic today.
In the United States, the path that led to the development of equipment suitable for use in areas at risk of explosion has followed an almost parallel path to Europe, addressing the issue first in the mining industry and then extending it to electrical devices in the NEC. The use of still current techniques demonstrates how much the more traditional methods of protection can boast a history of reliability and safety spanning more than a century.
His excellence Dr Sultan bin Ahmed Al Jaber focuses on local ICV certified companies such as Cortem Gulf that bring technological value and know-how to the Emirati industry for the development of the local production fabric
The systems are mainly divided into systems with metal protective conduits and cable systems. The various devices require cable entries suitable for the type of protection used. The type of cable entry may appear to be a mere theoretical argument, but it has a decisive impact on the safety level of the system.
The most used entry systems are: entry with sealing fitting, cable entry with Ex barrier cable gland, cable entry with Ex cable gland with sealing ring. When we talk about electrical systems with electrical cable installation, entries are made using a cable gland, which can be of two types: barrier or with sealing ring.
A year and a half after the launch on the market of the aluminum LifEx series, Cortem Group enriches this family of lighting fixtures with the LifEx-P series
Cortem Group presents the third generation of LED lighting fixtures for areas at risk of explosion
Cortem Group will supply Technip and Enppi with 6,500 lighting fixtures, obstacle signaling lighting fixtures, over 5,000 enclosures, motive power panels and grounding systems.
In areas at risk of explosive atmospheres, systems with electrical cable installations are nowadays a valid alternative to traditional systems with conduits systems. Their diffusion has been driven by the increasing presence of increased safety equipment such as junction boxes or 'Ex eb ' lighting fixtures, which implicitly lead to the need for sections of the system with cable installation.
Project Agreement provides for the supply of Lighting Fixture, Junction Box & Socket Outlet
In sites where there is a risk of the formation of an explosive atmosphere, we often find the electrical conduit in a metal protective tube (also called conduit conduit). Although it has recently been joined by more versatile armored and non-armored cable systems, with cable gland entry, its use is recommended in plants where production or use and maintenance activities can present dangerous situations for the integrity of the cables.
Today we define the methods of protection as techniques that are made available to us by harmonized standards, to satisfy the Essential Health and Safety Requirements. It appears clear how the first decades of the twentieth century proved to be fundamental for the development of the techniques underlying the current methods of protection.
The first Cortem Group's certified products
Sealing fittings are often considered only as secondary or minor components, but the safety of an installation with metal electrical conduits and related explosion-proof enclosures depends on them. The main function of a conduit sealing fitting is to prevent the propagation of an explosion from the inside of the ‘Ex d’ flameproof enclosure to the outside.
Buenos Aires 20-23 March
Nowadays, the classification in an area at risk of explosion concerns many sectors of the industry and includes the use of the most diverse equipment. This great variety of devices and applications must not make us forget that the origin of explosion risk containment techniques lies down there, in those dark mines where it all began.
Explosion-proof joints are one of the basic aspects of the protection offered by an equipment or an explosion-proof enclosure. For this reason, understanding their function is a prerequisite for the correct use and the proper maintenance of all electrical devices that adopt this type of protection.
The 'Ex d' type of protection, now referred to as 'Ex db', is based on a simple theoretical concept: containment by means of a sturdy casing and flame retardancy. Its success is due to this simplicity, it is in fact one of the first methods of protection developed in the mining industry and still today it is one of the most widespread in areas classified for potentially explosive atmospheres.
A fundamental principle of the ATEX Directive 2014/34 / EU, shared with the other Union directives, is the limitation of legislative harmonization to essential health and safety requirements of public interest. Within this legislative harmonization, a role of primary importance is played by the harmonized technical legislation and the concept of the state of the art. The ATEX Directive refers to this concept as a requirement requested of manufacturers.
In the world of ATEX equipment a key role is played by notified bodies (as defined in the ATEX Directive), also called certification bodies (in Italian legislation 60079-0). These are third parties called to certify certain product and quality standards.
We are waiting for you! HALL 7, BOOTH #7704
ATEX device's manufacturers use different types of protection to achieve a certain EPL. These methods of protection are constantly evolving both technical and regulatory. In any case, the most used are those that have established themselves historically.
Each equipment that must be installed in an ATEX classified area must have a certain level of protection, indicated in the legislation with the acronym EPL (Equipment protection Level). The level of protection is obtained by applying technical regulations that define the protection methods. There are many ways of protection, some have a historical origin, others are more recent...
New and more performing models with LED board available
Application of some simple rules to make a first match between the equipment and the installation site based on EPL, gas group and temperature class of the equipment.
The installer must have clear and defined the information relating to the level of protection guaranteed against the risk of explosion regardless of the function of the device. This information can be found in the marking of the device and it is completed with the instructions for use.
Installers and designers often ask themselves questions relating to the choice of the right electrical appliances to be installed on the plant site. This choice depends on a series of parameters, among these we will deepen the probability that an explosive atmosphere can form (concept of zone) and the type of substances involved in this formation (concepts of GAS group and temperature class).
