    Switchgear short circuit ratings are based on two 30-cycle withstand tests with 15-second interval, AKD-10 switchgear sections are provided in either 22", 30" or performed at 15% power factor and 635 Vac maximum. For 38" widths. It is designed to be operated in an ambient tem- switchboards, a single 3-cycle withstand test at 20% power perature between -30°C and 40°C (-22°F and 104°F).
  • Page 5: Safety And Reliability Features

    Safety and reliability features Standard and optional features are available with AKD-10 switchgear in order to meet the increasing industry emphasis on maximum uptime, system reliability and operating personnel safety: • Closed-door operation Breaker compartment doors have no ventilation openings, thus protecting oper- ators from hot ionized gases vented by the breaker during circuit interruption.
  • Page 6 A superior bus system offers different levels of protection: • Fully tin-plated copper bus Fully tin-plated copper main and riser bus is a standard feature on AKD-10 equipment. Tin plating provides superior corrosion protection, especially for application in the pulp and paper and waste treatment industries where corrosive agents routinely exist.
  • Page 7 • Drawout padlock provision (standard) WavePro and AKD-10 offer an array of standard, safety locking features that provide extra measures of security when breaker, equipment, or load mainte- nance is performed. In addition to the padlocking feature on the breaker that keeps it open and tripfree, WavePro breakers are also equipped with provisions Œ...
  • Page 8 • Key interlocks This option allows locking of the circuit breaker in the open, trip-free position when fully connected. Applicable schemes would be mechanical interlocking of two breakers so only one can be closed at a time, or, in load center unit substa- tions, interlocking of the primary switch and secondary main breaker such that the secondary main must be open before the primary switch can be operated.
  • Page 9 GE’s manufacturing processes and testing set the quality standards in the switchgear industry: • Paint finish AKD-10 switchgear is protected by the “E-coat” paint system consisting of a “cathodic electrodeposition” process employing the same principle used in electroplating: An electrically charged object immersed in a bath of oppositely charged particles will attract, and become coated with, those particles.
  • Page 10 = 0 indicates the switchgear is installed at ground level. z/h > 0 indicates the switchgear may be installed anywhere in the building. AKD-10 has been certified for use in all IBC-2003 Seismic Use Groups, Occupancy Importance Factors and Seismic Design Categories. In addition, AKD-10 has been qualified to IEEE-693-1997 for Moderate and High Seismic loading conditions.
