Applications (for Explosion-Proof Motor):
Hazardous environments with explosive gas or vapors should
adopt a
explosion-proof motor to prevent explosion or fire hazard which cause
substantial damages to people and properties. Some examples of these
dangerous environments include:
1. Places with flammable gas or liquid stored inside concealed
machineries or containers. In the event of sabotage, operating error or
omissions, the explosive gas or liquid can leak to inflict danger;
2. Places similar to (1) listed above but equipped with ventilation
device to prevent gas explosion. Again explosive
gas leakages can occur when the ventilation device
malfunctions;
3. Places close to (1) and (2) above where dangerous levels of explosive
gas are present or are likely to get inside.
Features (for Explosion-Proof Motor):
- This explosion-proof motor conforms to the stringent
Taiwan's National Standards (CNS). Its design is aimed at
eliminating any unusual sparks, electric arcs or over-heating which can
occur in wire wrapping, stator and various other places
inside the motor. This highly precise and reliable motor
greatly enhances operational safety.
- Design of the motor's fan housing conforms to European Union (EN294)
requirements. Another assurance on its durability and product safety.
- Built using heat and chemical tolerant insulative material for
improved safety and longer useful life.
- Under the requirement of revised CNS, the motor's specifications
comply with IEC international standards for better interchangeability
and easy of install.
- Taps complying with BS 4999 specifications are included for better
flexibility and convenience of use.
