DXB(W)–10 Outdoor Package Substation is an outdoor combined distribution complete set apparatus used in 3-phase, 50Hz, 6 ~ 35kV power systems.  With reasonable design, the package substation combines high voltage switchgear, transformer, low voltage electric apparatus into one or several cases organically, suitably used in city’s residential areas, industrial and mineral enterprises, mineral sites, oil fields, wharves, airports as well as a temporal power supply equipment for civil sites.

 

 

2.1        The frame structure of the substation is made of channel steel and angle steel resulting in high mechanical strength.   Its enclosure is made of aluminum alloy sheet and other equivalent material which is even and smooth in surface, good looking and anti-corrosion.

2.2        The compartments in substation are separated indepently with partitions in between.

2.3        Double tier structure for the top cover avoids direct thermal radiation.

2.4        There is drain fan mounted at top of the transformer to control temperature of transformer compartment automatically and enhance air convection to lower the room temperature.

2.5        There are lighting lamps controlled by the door in transformer compartment, low voltage compartment and high voltage compartment for the convenience of inspection and reparation.

2.6        Rotational linking parts are sealed with rubber bends with better wet-proof performance. 

 

 

3.1        Altitude not over 1000 meters above sea level

3.2        Ambient temperature not higher than +40℃ nor lower than -25℃

3.3        Outdoor wind speed not exceeding 35m/s

3.4        Relative humidity daily average not greater than 95% at 25℃ and monthly average not greater than 90% at 25℃

3.5        Places where there is no frequent severe vibration and shock

3.6        Places where there is no inundation, potential explosion, nor severe pollution, chemical corrosion. 

 

HLA, HNB, DZX10, DW15 and ME are adopted as main circuit breakers whereas DZX10, DZ20 are adopted as branch circuit breakers.
