AGRO Ex cable glands. Professional cable glands for potentially explosive atmospheres.

Explosion protection. Necessary more frequently than you might think. In the 19th century, electrical technology made its way into both industry and the home. Immediately thereafter, the first fundamentals for protection against electrical explosions were developed because of the methane gas and coal dust which arose during the mining of anthracite coal. The advantages of electricity were so overwhelming that people started working intensively to come up with ways to prevent any possible meeting of explosive atmospheres and ignition sources – resulting from the use of electrical equipment –...

Directives and regulations Directive 2014/34 EC The new directives 2014/34/EC of the European Parliament and of the Council of 26 February 2014 on the harmonisation of the laws of the Member States adress manufacturers and users of equipment and protective systems for use in potentially explosive atmospheres. Since 20 April 2016 only products approved according to the new directions and with EC declaration of conformity can be brought to the market. The old certificates according to the former directives 94/9/EC remain valid. A recertification according to the directives 2014/34/EU is not...

Prerequisites for certification In the annex of directives 2014/34 EC various modules for the commercialisation of equipment intended for use in potentially explosive atmospheres are defined. Modules III and IV are often used and applied at AGRO as well, and from them two certificates result: • EC type-examination certificate • Recognition of production quality assurance Both certificates are issued by accredited testing facilities after tests have been successfully completed. EC type-examination certificate The EC type-examination certificate is the document which is issued on the base of...

What protective measures can be taken to reduce the danger of explosion? Conditions for an explosion As a rule, an explosion can only take place in atmospheric air if three factors come together: • a flammable material • oxygen (in the air) • ignition source The first two factors – flammable material and air – must be present in a corresponding concentration so that they can form an explosive atmosphere. Descriptions of explosion protection are thus in general limited to the depiction of reactions with oxygen in air. Oxidation reactions which are generally associated with the generation of...

Explosion groups Within the explosion groups, for electrical equipment a first distinction is made between Equipment Group I and Equipment Group II. Electrical equipment in Equipment Group I is used for mines susceptible to firedamp. For electrical equipment in Equipment Group II, a further subdivision is made into explosion groups. The subdivision depends on the maximum experimental safe gap (MESG) and the minimum ignition current. Electrical equipment with approval for Explosion Group IIC may also be used in Explosion Groups IIA and IIB. Electrical equipment in Equipment Group III is...

AGRO Ex cable glands nickel-plated brass with safety bracket Flameproof enclosures Ex d IIC Certification including ageing and climatic tests Principle With ignition protection type Ex d IIC, components which can ignite an explosive atmosphere are arranged in a housing. This housing must contain the pressure of the explosion and an explosive mixture within itself, and it must prevent the explosion from spreading to the explosive atmosphere surrounding the housing. Cable glands for flameproof enclosures are tested according to IEC/EN 60079-1 for the following points: - mechanical design and...

Ex e II principle In the case of ignition protection with an increased safety type, operation is based on the equipment preventing ignition of the explosive atmosphere which can also leak into the housing. The equipment may not reach temperatures which are above the temperature class of gases which could potentially arise in the...
