HONR-S segregated, three-phase, rectangular busducts (SPB busducts)
Design:
The segregated, three-phase, rectangular busducts is a shielded, self-supported, naturally cooled and air-insulated busduct.
Three phase conductors are arranged symmetrically in a common housing and attached to support insulators.
The individual phases are separated by a metal barier. This ensures greater resilience of the busduct to phase-to-phase short circuit faults.
The use of maintenance hatches allows for monitoring the condition of the support insulators and possible replacement.
Delivery includes:
- busduct,
- tap-off busducts for auxiliary transformers, chokes,
- connections to the apparatus (generator, transformers, generator circuit breaker, cabinets),
- supporting structures,
- transformer, lightning arrester, capacitor cabinets,
- high-current disconnectors.
Electrical parameters:
- Conductor material: aluminium or copper,
- Enclosure material: aluminium,
