Pipe Clamps for Ex Zones 1/21, 2/22

So far equipotential bonding and lightning equipotential bonding of pipes in explosion-hazardous areas have been implemented by means of welded or threaded bushing connections. Clamps may only be used if evidence of no ignition sparking in case of lightning current loading is provided. The pipe clamp of DEHN is in compliance with the requirement for devoid of ignition sparks at lightning current loading. The clamp has been tested according to EN 50164-1 title English: Lightning Protection Components (LPC) - Part 1: Requirements for connection components in a potentially explosive atmosphere (clamps and connectors), and provided proof of no occurrence of ignition sparks at a lightning current loading of up to 50 kA (10/350 µs). This novel, patented pipe clamp for hazardous areas not only ensures safe electrical contact by means of two contact clips, but also adequate mechanical fixing by an electrically insulated clamping body.

The Ex pipe clamp provides the following connection possibilities:
– Round conductors made of Cu, St/tZn, Al, StSt with Ø8/10 mm or flexible / stranded copper conductors, cross section 16-35 mm², with E-Cu crimping cable lug (DIN 46235)
– Flat copper conductors, min. 20 x 2.5 mm, with bore Ø10.5 mm
