001 Q What is electrical switchgear
A Electrical switchgear is a key component in electrical power systems and is used to both distribute electrical

power and to selectively isolate electrical loads. The switchgear is a switching device comprising of connecting or disconnecting switches, fuses or circuit

breakers, protective and controlling devices which can be used to isolate electrical apparatus in faulty

condition or during maintenance period, or to connect the same in desired healthy conditions.

002 Q Do we need to monitor the switchgear conditions
A Yes, Because switchgear distributes electrical current, heat build-up becomes an important characteristic

to monitor. In particular, unexpected temperature rise at a particular location could indicate corrosion or

some other type of defect. Thermal effects are especially visible in medium voltage switch gears used

in distribution networks, where electrical currents may rise to few thousands of amperes. Thus keeping

switchgears in proper condition over their long life becomes a critical issue.

003 Q What are the main causes of arc flashes in industrial switchgear?
A The main causes of arc flashes in industrial switchgear are: the application of tools to energize switchgear,

deteriorated insulation on phase bus bars, and loose electrical connections that overheat. These things can

be prevented by proper safety measures and regular maintenance.

004 Q What is the lowest voltage at which arc flashes occur?
A 120 volts is generally considered the lowest voltage at which arc flashes occur. The voltage of industrial

switchgear can exceed this voltage by hundreds of thousands of times.

005 Q What is Metal Enclosed Switchgear?
A Metal Enclosed Switchgear is a switchgear assembly that encloses all necessary equipment and device in

separate metal vertical structure (i.e MCCs, PCC), however they each metal compartment are not separated

from one another by metal barriers. It’s used often with low voltage equipment.

006 Q What is Metal Clad switchgear?
A Metal Clad Switchgear is a switchgear assembly that encloses all necessary equipment and devices in one

metal house, but compartments in this assembly is separated fromone another by metal barrier. When metal

clad switchgear is used or assumed when MV switchgear is provided.

007 Q Difference between Metal Enclosed Switchgear and metal Clad Switchgear.
A Metal enclosed switchgear: Assembled with separate metal vertical section Metal Clad Switchgear: Assembled in one metal structure. MES: each compartment is not separated from one another with metal barrier. MCS: each compartment is separated from one another with metal barrier. MES: Frequently used in LV system. MCS: Frequently used in MV System. When MCS is said MV Switchgear is assumed. MES: All breakers and other switching devices are fixed type. MCS: All breakers are withdrawable type.
008 Q How’s your electrical switchgear waranty?
A Once you buy the product manufactured by Jiangxi Yikai Electric in China can get 24 months waranty after delivery date.
