Bus duct which is mainly composed of metal enclosure, busbars and flexibles conductor has high flexibility in design and application of installation compared to power cables. Busduct can be installed in many kinds of field such as a modern building and an electrical substation with high reasonability and safety. Nissin Electric manufactures two types of bus duct system, and it enables to provide the stable power supplies wherever it is required.
Shunt reactors are connected in parallel to the power grid. They supply the necessary lagging reactive power to compensate for the leading reactive power (earth capacity of the system) to help stabilize the system voltage.
Switchgears receive electricity at the specified voltage, increase or lowers the voltage, and distribute electricity to respective loads to supply electricity safely. They are stored in a metallic enclosure so that they can be used safely over the long term. They are equipped with switches for operating equipment, meters for measuring voltage and current, etc., and protection relays for detecting abnormalities, among other instruments.
