PHASE SEGREGATED TERMINAL BOX
We are Manufacture of wild range of Phase segregated terminal box. The terminal box fabricated Mild steel casing welded to a heavy gauge back and front plate. The outer Mild steel case encloses an inner fabricated Mild steel shell and mild steel barriers extending from top to bottom of the inner shell. The terminal box has three segregated phase compartments. The presence of the inner skin prevents an internal arc from flame cutting a hole in the outer casing, preventing hot gases discharging into the atmosphere with consequent danger to personnel. As an additional safeguard, the terminal is enclosed within Fiber glass molded type enclosure. Cables from the equipment interior and the intermediate cables pass through moisture tight compression glands in the enclosure. Gaskets prevent the ingress of dirt or moisture. Each compartment is fitted with a desiccators unit which provides a visual indication of moisture within the box in any phase. The desiccators unit can be removed while the equipment is energized.
Phase segregated terminal boxes eliminate phase to phase faults. In the event of a fault developing between phase and earth in one of the fiber glass terminal enclosures, the rapid build up of pressure will cause the enclosure to fracture across the rear wall, thus releasing hot gases and flame into the Mild steel phase segregating compartment.
If the fault energy is low it is likely that the fault products will be contained within the compartment. If the fault energy is excessive, then the relief disc will fail and the fault product will pass into the equipment interior where it will rapidly cool and disperse. By venting into the equipment space, phase to phase faults are eliminated.
