Oil-immersed Power Transformer Installation and
Operation Manual. The instruction manual applies to the low-loss oil-immersed power
transformers with the capacity up to 6300KVA.
is a kind of indoor and outdoor compact
distribution equipment. It combines the high voltage switch equipment, distribution
transformers and low voltage power distribution equipment together.
Basic knowledges about distribution transformer,
including definition, types like oil immersed type, dry type, pad mounted type, pole
mounted type. Distribution transformer is a transformer that provides the final
voltage transformation in the electric power distribution system, stepping down the
voltage used in the distribution lines

Explain difference between AIS and GIS. MV
switchgear is an important part of power distribution system for maintaining the
continuity of service, and you have to consider some different aspects based on your
needs before selecting a suitable MV switchgear.
What is ACR Auto Recloser? Auto recloser (ACR)
also named automatic circuit recloser is recognized by electric utilities throughout
the world as an essential device for achieving their prime goal: providing maximum
continuity of electric service to customers.
The article introduce some differences between
dry type transformer and oil immersed transformer. It can help you understand these
two different types and help you make desicions.
Difference Between DC Charging and AC Charging.
AC charging has lower power, requires longer charging time, but has less loss to the
battery. On the contrary, DC charging pile has higher charging power, faster
charging, but has greater loss to the battery.
What is Distance Protection Relay? Distance
protection relay is the name given to the protection, whose action depends on the
distance of the feeding point to the fault. The time of operation of such protection
is a function of the ratio of voltage and current, i.e., impedance.
The professional VCB vacuum circuit breaker
manufacturer.
Rockwill Electric is the professional manufacturer and designer and patent woned
factory of Medium voltage and high voltage VCB vacuum circuit breaker from China.
What is compact substation CSS? The CSS Compact
substation is actual a prefabricated eletric equipment unit which is comprising of
MV / HV switchgear, Power Distribution transformer, LV switchboard, Connection
busbar and other accessories.
Ring main unit (RMU) is a set of high voltage
switchgear installed in the steel plate metal cabinet or made into an assembly
interval ring network power supply unit. The core part adopts load break switch and
fuse, which has the advantages of simple structure, small volume, low price.
China outdoor SF6 load break switch (LBS) which
is a capable small fault current breaking switchgear. It is a disconnect switch that
has been designed to provide making or breaking of specified currents.
What is capswitch capacitor switch?
A Medium voltage or High voltage Capacitor switch or Capswitch is a special
switchgear for application in switching capacitive load network. It can be vacuum
type or SF6 gas type.
What is a AVR step voltage regulator ?
A step voltage regulator helps prevent a poor-quality signal from being sent over
distribution lines to users. Step voltage regulators are mainly used in utility
distribution applications for the disbursement of electrical signals to properties.
