APPLICATION

• generator leads in power stations and heat & power plants,
• connections between electric power equipment in high short-circuit capacity systems,
• single phase connections of generators with main, auxiliary or excitation transformers,
• interconnections in auxiliary service power system of transformer stations,
• in highly polluted or humid environments,
• not applied for rooms in danger of explosion.

GENERAL CHARACTERISTICS

• reliable and economical electrical power installations for voltages from 12 kV to 36 kV and rated current 1.25 kA to 24 kA,
• suitable both for indoor and outdoor operation,
• degree of protection up to IP 65,
• optional design with pressurized dry air.

DESIGN

• medium voltage busducts type ELPE are designed as single-phase conductors enclosed by an individual tight, self supporting housing which serves as a screen, supported inside the enclosure on cast resin or porcelain insulators,
• conductors made from shaped aluminium or copper bars, welded or bolted,
• connections of ELPE bus to the generator, transformers or switchgear cubicles are made with copper flexible straps which provide the best short-circuit withstand level,
• enclosure made from sheet aluminium,
• modern silicone bushings are provided in busducts with dry air overpressure,
• electrical equipment used in ELPE busducts is enclosed in special housings,
• self cooling of conductors and enclosure.

The standard ELPE system for generator lead:

• connection form generator terminals to the main transformer,
• tap-offs to other transformers,
• generator "star" connection,
• earth fault protection cabinet,
• connection to the switching equipment,
• supporting structure.

FEATURES

• possibility of adjusting the standard design to individual needs of the user and providing additional equipment,
• new techniques of design, manufacture and assembly which enable manufacture of IPB for special service conditions,
• optimising electrical and mechanical parameters (at customer’s request),
• self-supporting structure enabling many meters long spacing of supports,
• expansion joints on the conductor and the enclosure eliminate the problems of linear expansion forces,
• inspection and maintenance windows for control and easy access to insulators, apparatus and bolted connections,
• short time of assembly on site due to advanced prefabrication and modern erection methods,
• low costs of operation,
• corrosion resistance,
• electric-shock safety,
• environment friendly
