Busbar system | DURESCA®
Fully insulated busbars are used to ensure connections between medium and High Voltage equipment such as generator, switchgear or transformer.
The DURESCA® busbar have their field of application from 12 to 170kV and up to 7000A.
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 and partial discharge free operation.
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.
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
Specifications and Downloads
Technical Specifications
- Same type of busbar for indoor and outdoor application, no need of additional wall crossing bushing
- Solid, separate and fully insulated single phase bus
- Excellent mechanical protection
- High stability against UV radiation
- Earth screen in copper, embedded in the insulation and designed for an exceptional fault current of 8 kA /1s
- Resistant to humidity and moisture ingress, no risk of corrosion
- Connections to all types of air and gas insulated switchgears with conventional or plug-in types, like 8DB10, NX plus, ZX2, GHA or Connex 3 and 4 size
DE and DG type busbars
- The insulated body is protected by a high-quality corrugated polyamide tube or metallic tube.
- The good behavior in severe climatic conditions has been tested according to the ASTM D-2565 standard in an independent laboratory.
- Moser-Glaser has been using this type of protection jacket for more than 30 years.
- This solution can be used for projects with higher mechanical requirements, e.g. aluminum or stainless steel tube.
Standards and tests for DURESCA® Busbar systems
Every busbar is routine tested according to IEC 60137 standard, clause 9.1, 9.3, 9.4.
- Power frequency withstand voltage
- Partial discharge
- Capacitance and tangent delta
