ATEX rated cable entry systems

The ATEX (Ex) directive applies to all explosive industrial atmospheres including mining, with the icotek range of cable entry systems being suitable for zones G (gas) and D (dust) in equipment group II, category 2, certified to the ATEX directive.

The specific icotek products now ATEX rated cover two sets of cable entry frames being the KEL ATEX and the KEL-ER ATEX. These are split frame systems which are used with varied split grommet inserts to accommodate both un-terminated and pre-terminated cabling in a wide range of cable diameter options. Reduced installation times can be achieved while retaining the pre-terminated cable warranties, and also ensuring that any retro-fitting of cabling or routine maintenance can be quickly and easily accommodated. With a range of frames and inserts being available, high packing densities can be achieved.

Installations are vibration proof with automatic cable strain relief provided to EN 50262. Four frame sizes are available in each range with the KEL ATEX system covering 24 single or mixed groupings and cable O/D sizes while maintaining an IP54 rating. The KEL-ER ATEX split frame system provides an IP65 rating with 20 options of cable groupings and sizes.

Cable entry plates include KEL-DPZ ATEX products in both rectangular and round options. The rectangular products cover cable diameters from 3.2 to 22mm and incorporate membrane sealing with IP65/IP66 rating as well as automatic strain relief. The round cable entry plates in the range cover the same standard cable sizes but with an immediate dual seal rating of IP68. They can be used for standard or metric cut-outs with polyamide locknuts also provided.

A split cable gland assembly KVT 80 ATEX is also available, particularly suited to routing and sealing pre-terminated cables with bulkhead thicknesses from 1.5 to 10mm. Where larger undetermined cable diameters need to be accommodated, then the KEL-DPF ATEX cable entry inserts can be utilised. These can also accept rigid pipework or cabling where angled entry needs to be accommodated.
