Specialized in custom processing of thermal (glass-cement, calcium silicates …) and electrical (FR4, G11, GPO3 …) insulating materials, Lenoir Elec has developed a substitute to cement-asbestos for electrical engineering field: COLOMIX 71 S, a cement-glass composite officially recognised by railway companies (SNCF in France, SNCB in Belgium) and the French national power utility.
Colomix is an asbestos-free thermoelectric insulating material, which can be compared to the cement-glass composite family. It makes machining easier (milling, pumicing, sawing, turning, etc.) and offers physical properties to match conditions of use (high temperatures, mechanical constraints, etc.). More particularly it is well suited for manufacturing of blowout cages used in circuit-breakers and bar contactors and has outperformed original asbestos-made products (reduced breaking time).
To always provide the solution best suited to your requests, the Insulation department has suitable resources:
- Qualified staff
- 4 machining centres, 2 CN towers, CFAO …
- A metrology unit equipped with a 3D measurement machine
Lenoir Elec Insulators department is working for various fields of activity where its innovative solutions are highly appreciated: petrochemicals, glass, foundries, traction, cryogenics, electrotechnics.
