STAUFF has expanded its range of tube, hose and cable clamps for modular use in the standard series as per DIN 3015, part 1 with a special clamp body version of type CHC for guiding and fixing corrugated conduit hoses which are commonly used on mobile machinery and in stationary hydraulics. These hoses are typically used for protecting and bundling electrical or other lines.
The special feature: in contrast to using conventional clamp designs typically with a smooth or profiled inner surface, the fixed corrugated cable protection hoses are now held firmly and securely in place – but without significant pre-tension – thanks to the special design with a single rib in the clamp body. Correct installation provided, axial sliding of the corrugated hoses, which can cause damage to the hose or the contained lines, is impossible – even for vertical installation or under significant movement within the machine.
Insert made from thermoplastic elastomer, which reduce the internal diameter of the clamp body to commonly used external cable diameters between 7 and 18 millimetres, now extend the possibilities to use the system. Individual cables can be guided safely and without any risks of damage.
System planners and line installers benefit from one essential advantage: The known and proven DIN clamps from STAUFF can now be used for additional line types – cables and corrugated conduit hoses – with optimum results, while retaining the familiar work processes and without requiring double stock-keeping of metal hardware such as cover plates, weld plates and bolts. This also provides a uniform appearance of the system.
Clamp bodies of type CHC are available for the most common nominal corrugated conduit hose sizes from 10 to 48, i.e. with external diameters between 13 and 55 millimetres, as a standard. They are manufactured from glass-fibre reinforced Polyamide and have excellent resistance to weather, temperature and media – perfect for difficult outdoor conditions.
As an alternative, versions made of special flame-retardant materials in compliance with international fire protection standards (e.g. as per BS 6853, EN 45545-2 or UL 94) can also be provided.
