Isolated Phase Bus Duct

The isolated phase bus is a large current transmission device widely used in the outgoing line circuit of 50MW and above generators and the auxiliary branch circuit. DAQO offers the busbar solutions from 10kV - 35kV & 1000A-30000A including sections from generator phase terminals to GCB & GCB to main transformer with tap off run to Unit auxiliary transformer

Segregated Phase Bus duct is a metallic enclosure housing busbars of all the three phases. The three phases are segregated from one another using Aluminium or Insulating barrier. The SPB is being used for interconnection between Transformer and Switchgear in Power Plants or in Heavy Industries

The Insulated tubular bus duct series is applicable to power supply, power generation, metallurgy, petroleum, chemical, energy and other power distribution projects. Its advantages such as small floor area, large current carrying capacity, high safety factor, and convenient maintenance have been accepted by the majority of users.

Lightening Arrestor & Voltage Transformer cubicle employ draw-out construction with interlocking features to protect against hand touch access to the high voltage connection points in both the operating and withdrawn positions.

Ring type current transformers are mounted on a flange inside the enclosure. Installation and removal of these transformers is carried out through an inspection door sized for this purpose. The secondary windings are wired out of the enclosure, via a sealed box provided with a cable inlet stuffing box.
