Fla 15/60 N - new designs

single-pole and three-pole design
rated voltage 25 and 38.5 kV
rated current 400 and 630 A

Outdoor design, load disconnectors of Fla 15/60 GB N, Fla 15/60 GB R N and Fla 15/60 GB S N series have been developed by the DRIBO company as design version of the Fla 15/60 load disconnectors which prove its high reliability and operation safety since many years on the world market.
The switching takes place in proven and tightly closed arc quenching chamber filled with Shell transformer. Each arc quenching chamber contains about 0.5 l of oil.
The load disconnectors comply with requirements of the following standards: EN 62271-1 and EN 62271-103. Used insulators satisfy the fourth grade of contamination area.
All current carrying components are made of silver plated electrolytical copper and constitute a loop-less current conduction path.
The cross-section of the conductors the current-carrying path consists of is sufficiently dimensioned. Appropriate contact pressures of the stainless steel springs are one of the prerequisites for a fault-free switching even after many years of load disconnector’s operation under extreme operating conditions and also under hoarfrost loads.
The load disconnectors are delivered with insulators made of a cyclo-aliphatic resin or silicone.
