Main Characteristics:
Sturdy housing which prevents an internal explosion from spreading to the outside and resists the explosion pressure Robust bearing shields and caps bolted to the frame in such a manner that the gaps remain unaffected in the event of an internal explosion Screen on air intake with a mesh size not exceeding 8 mm External earth terminals Protective earth conductor terminal in the terminal box “Ex ‘d’” mark on the motor CIMFR certificate No., PESO and DGFASLI certificate No. and ISI Licence mark on the name plate Special varnishing and painting treatment to resist highly corrosive atmosphere.
Enclosure Design:
The frame, end shields, terminal boxes and bearing covers of all motors are made of grey cast iron. The motors are so designed that the frame temperature will remain below the ignition temperature of the gas-air mixture.
Insulation:
All motors of standard design are provided with Class F insulation with temperature rise limited to Class`B’
All motors of standard design are provided with Class F insulation with temperature rise limited to Class`B’
Cooling:
