HONR non-segregated three-phase rectangular busducts
Non-segregated three-phase rectangular busducts are used in distribution systems where resistance to severe environmental conditions is not required. HOLDUCT provides three-phase busducts optimized for the needs of the customer in order to obtain the greatest savings possible through:
- reduction of losses,
- reduction of assembly time,
- busduct trunking and support structure configuration.
Our support engineers are ready to help you even at the stage of the development of a power plant concept project.
Design:
A non-segregated three-phase rectangular busduct is a shielded, self-supporting, naturally cooled air-insulated busduct.
Three phase conductors are arranged parallel in a common housing and supported on supporting insulators.
The use of maintenance hatches allows for monitoring the condition of insulators and their possible replacement.
Delivery includes:
- busduct,
- tap-off busducts to auxiliary transformers, chokes,
- connections to apparatus (generator, transformers, generator circuit breaker, cabinets),
- supporting structures,
- transformer, surge arrester and capacitor cabinets,
- dry-air overpressure system,
- High-voltage disconnectors.
