NOTE ON SMC & DMC SUPPORTS & INSULATORS
All Switch gear & Electrical panels are combination of current carrying conductors & non current carrying structure. To separate & support the current carrying busbars from the structure, busbar supports & Insulators are used. These supports / insulators should be designed to bear electrical & mechanical stress during the normal & fault conditions. They should also comply others features like Nonhygroscopic, Fire Retardant, chemical & Corrosion Resistance.
Asian busbar supports & insulators are made of SMC (Sheet Moulded Compound) / DMC (Dough Moulded Compound) manufactured with a combination of resin and other additives under controlled temperature and pressure, to produce components with excellent alround properties and characteristics.
High die electric & mechanical strength
High temperature withstand capacity
High strength to weight ratio
In insulators the inserts are made of EN1A which has better tensils strength as compared to MS & Brass (e.g. ENIA-600 Mpa, MS-300 Mpa, Brass- 150 Mpa) & has least chances of thread failure as compared to others
