fuse disconnect switch(DS) outdoor high voltage isolate switch is the high voltage switch equipment of composite strudcture, is suitable for outdoor 22KV line net with voltageand no load, to make opening and close. With type manual operate machinery, can avoid earth line with power and composite flash-locks ets.
Transformer can transform the voltage of a network into the voltage matching the system or load and fulfill power transferring and distributing.Taking the place of transformers with silicon steel core, AMDT can be widely applied in outdoor power distribution networks systems, which is magnificently energy saving and can lessen air pollution. It is especially applicable for areas with insufficient power supply and fluctuating load and where daily maintenance is hard. Since the transformer adopts a fully sealed structure, the insulating oil and the insulating medium are not polluted by the atmosphere, so it can be carried out in a humid environment, making the ideal power distribution equipment in the urban and rural distribution networks.
A current transformer (CT) is a type of transformer that is used to reduce or multiply an alternating current (AC). It produces a current in its secondary which is proportional to the current in its primary. Current transformers, along with voltage or potential transformers, are instrument transformers.
Drop out fuses and load-drop fuses are outdoor high voltage protection appliances. It is installed on the high voltage side of the distribution transformer or on the branch line of the distribution line. used as a short circuit of the transformer and the line, overload protection and split load current.
