Colomix 71Elec Colomix 71 for the replacement of old asbestos arc chutes.No one needs to explain how harmful asbestos is. For years people working in all typesof industries were exposed to it. Electrotechnology was no exception: asbestos cementwas widely used for its excellent thermal and mechanical characteristics. With Colomix71, we developed a material that presents no hazard to human health, is easy to workwith, has excellent mechanical strength and can be machined to any shape. Colomix71 has the thermal and insulating properties to withstand extremely high temperaturedensities and dissipate electric arcs. In fact, replacing asbestos blow-out cageswith Colomix 71 leads to better performance. Colomix 71 is a mineral insulator forelectrical and thermal applications consisting of 59% hydrated aluminum silicate, 38%wollastonite (calcium silicate) and 3% glass fiber. It has excellent mechanical strengthat high temperatures (600°C). “S” grade is recommended for electrical applications.Finished parts of that grade are impregnated with high temperature resin.Features/Benefits:Colomix 71 is a patented product that is designed to aid in the replacementof cement-asbestos blow-out cages equipping contactors created by an oldergeneration of manufacturers. With Colomix 71, you can create an indentical matchof your existing blow-cages, while maintaining the equipment’s genuine technicalcharacteristics. This innovative material allows you to replace existing blow-cages,without launching a long and expensive R&D study. With Colomix 71 there is noneed to change the whole breaking system (circuit breaker, switch, etc.) — only theold blow-out cages with their asbestos shell need to be replaced. The Colomix 71offers an easy solution to maintenance and asbestos compliance.Highlights:This new generation of blow-out cages is 100% compatible with existing contactors.It does not downgrade the contactors in any way, ensuring their perennity. In addition,breaking capacities are notably improved due to a reduction in breaking times.Colomix 71 is available in three forms:• 1000x1000 mm sheets in its standard version(930x830 mm available only on request)• Parts to be machined per customers’ drawings, sample or specification• Molded partsApplications:••Replacement of all old asbestosarc chambers and arc chutesL14
