Dehn safety equipment for people and installations 
 


The DEHN Safety Equipment range offers an extensive programme of safety devices, both for persons and for installations, for all work on electrical installations, both under tension as well as disconnected. The range includes PPE, switch sticks, earthing and short-circuiting systems, voltage detectors, fuse rods, etc.

Working in and on electrical installations can be life-threatening. That is why the following 5 safety rules must always be respected.
 

The five safety rules at a glance
 

1.    Disconnect completely 
This means that the electrical installation must be disconnected from live parts on all poles.
 


2.    Secure against re-connection

Prevent the accidental reconnection of an installation during work. This can be done by replacing the fuses in the low-voltage grid with lockable lock-out devices. Interlocking devices to protect the workplace from being switched on again. The components are marked with the symbol "Do not close the circuit".
 

3.    Verify that the installation is dead
Use a suitable measuring / test equipment such as a voltage detector to verify on all poles that the installation is dead. Check the correct function of the voltage detector prior to using it. Capacitive voltage detector for checking all poles of medium-voltage installations up to 36 kV, including self-test of all live parts up to the test pin.
 

4.    Carry out earthing and short-circuiting
If the installation is dead, connect the cables and the earthing system with short-circuit-proof earthing and short-circuiting devices. Important: The relevant parts must be earthed before they are short-circuited! Earthing and short-circuiting devices with crimped cable lug for earthing and short-circuiting electrical installations at the workplace. Configurable online via the earthing and short-circuiting configurator.
 

5.    Provide protection against adjacent live parts
According to the five safety rules, adjacent parts are parts located in the vicinity zone. If parts of an electrical installation in the vicinity zone of the work location cannot be disconnected, additional precautions must be taken before work starts. In this case use insulating protective shutters or covering material as protection against accidental contact. Isolating shutters for protection against accidental contact with live parts of an installation at the workplace.
 


DEHN passive arc protection DEHNcare

Arcs faults are often caused by mistakes made when working on the switchgear or by contamination or foreign objects (e.g. forgotten tools, vermin ...).

An arc protection system provides the necessary safety to protect people effectively on the one hand and to optimise the availability of the switchgear and design it in accordance with valid regulations on the other hand.

DEHNcare offers reliable personal protective equipment (PPE) with an ATPV of up to 37.2cal/cm², maximum protection and perfect comfort.

    There is something in the air
    Supply lines can easily be overlooked and thus create additional accident hazards at the workplace. Poorly laid compressed air hoses or extension cables are not only a tripping hazard, but also a nuisance during transport and are not to be underestimated as a source of danger, especially when great importance is attached to the swift running of work processes.

    Mico Pro is Murrelektronik's innovative power monitoring system for use in 12 and 24 VDC applications with patented switch-off technology. Thanks to its modular structure, the system can be precisely tailored to the required application. This results in a very favourable cost-benefit effect. In addition, the system can be used very flexibly and takes up very little space. The patented switch-off characteristic ensures that your machine remains optimally usable. An additional advantage: an integrated concept for the distribution of potential that significantly reduces the amount of wiring in the switch cabinet.

    Coating specialist Alural makes its production more sustainable with Siemens
    Installing a powder coating and anodisation system that is not only more efficient, but also far more sustainable: that was the aim of the FOX or ‘Flash Oxidation’ project at the Lummen-based aluminium coater Alural. Siemens partners Breemes and IE Tech took care of supplying energy to the new installation using a Sivacon S4 power distribution board. Thanks to strong partnerships, the project was practically flawless.

    Compressed air: saving and electrifying
    Compressed air is ‘expensive energy’, especially if an installation has a lot of leaks. However, companies often pay little attention to compressed air as an expense and source of CO2 emissions. From a finance and CSR perspective, this means that they’re missing opportunities. Grinding disc manufacturer Saint-Gobain Abrasives took up the gauntlet and had itsme perform an ultrasonic test. This resulted in an overview of leaks and areas of potential savings. The company has already fixed most of the leaks and is now, once again with itsme, looking into electrifying certain drives. That will mean less wear, but moreover reduced costs, since electricity is cheaper than air.
