Product Description
Product Feature
■ GFM series busduct provides consistent strength and high short-circuit ratings. Under the protection of the enclosure made of aluminum or low magnetic plate, no hysteresis loss occurs on the distribution system with low temperature rise on housing, reduce energy loss on the whole system.
■ The hole for installation or maintenance can be set up at top or bottom of GFM, ventilated shutter can be set up on both side and bottom of the enclosure to improve heat dissipation.
■ When the length of busduct reaches between twenty and thirty meters , expansion joint can be set up in the basic settlement department. Thus, the busduct can be adjusted horizontally or vertically to offset thermal expansion of the busduct and errors caused by basic settlement.
■ Flexible braided straps are applied to eliminate the vibration of connected equipment. Rubber gaskets are adopted as shock absorber in the system to provide the elastic support to the insulator and the conductor. Moreover, the shock absorber can avoid the machinery vibration caused by equipment and the damage caused by earthquake.
■ Enclosure are painted with light grey painting in a very durable finish on the external surface with minimum absorption of visible light for better heat dissipation. Black painting on the internal surface would reinforce radiation and prevent the corona at the same time.
■ In winter, segregation device can be applied in the wall to avoid condensation happened due to temperature variation between indoor and outdoor in winter.
■ Silver-plating is applied to all joint and connection area. Silver-plating provides an extremely durable contact surface with better performance of lower contact resistance and anti-corrosion.
■ In order to avoid the resonance frequency range of the busbar and to reduce the electric power acting on the busbar, the type, specification and strength level of the insulator are preferred, and the span between the insulators is reasonably set.
■ Observation window can be installed in the connection area of busduct and transformer cabinet and generator cabinet, distribution cabinet so as to monitor the temperature rise by means of temperature measurement device or online intelligent monitoring system, which greatly improve the level of safety and reliability of operation and maintenance.
GFM Series non-segregated phase busduct is suitable for transmission system of 3 .6~40 .5Kv, rated current from 1000 to 6800A, AC 50~60 Hz, which is mostly applied in:
■ The electrical connection between generator and transformer;
■ The electrical connection between transformer and high-voltage distribution cabinet;
■ The electrical connection of AC excitater and rectifier cabinet;
■ The electrical connection of the excitation switchgear and generator rotor ring;
■ The electrical connection between other high-voltage main circuits.
