Busbar systems

• The DURESCA® busbar system provides a compact and a fully electrically shielded solution for power plants, substations, offshore windfarms
• The reduced bending radius allows the application in limited spaces. The individually insulated busbars are simple and quick to install and guarantee a long service life, maintenance-free and operation without partial discharges
• The DURESCA® busbars also withstand extreme conditions on offshore platforms, in petrochemical industries, and also in the desert with high sun exposure and temperatures above 50°C
• External insulation can be made of polyamide or corrugated metal casing

The DURESCA busbar system is available in two versions:

• DE type with polyamide protection tube in IP67
• DG type with metallic protection tube in IP67

• Totally enclosed medium voltage SF6 gas insulated busbar system for connections between GIS – switchgears and between GIS and transformers
• The copper conductors are centered with special high voltage epoxy insulators inside the outer aluminum protection tubes
• A separate control panel allows an accurate pressure control of the GASLINK® busbar system
• The excellent sealing between the compartments guarantee a maximum leakage rate of no more than 0,5% per year

• Busducts are used in systems of generator main leads for currents up to 30kA
• High reduction of the electromagnetic field and high resistance to short-circuit currents
• Conductor material: aluminium or copper
• Enclosure material: aluminium
• Short-circuit current: up to 1000kA
• Standards: ANSI, IEC
• Degree of protection: IP65

A single-phase busduct is an isolated, shielded, self-supporting, naturally cooled and air-insulated conductor.
Each phase conductor is encapsulated centrally in a individual enclosure and supported by post insulators. This eliminates phase-to-phase short circuits.
The individually designed support structures allow up to 30 metre spacing between the supports.
