Gas insulated, simple busbar cubicle range Up to 24 kV / Up to 36 kV CPG System Medium Voltage Switchgear Primary Distribution General description The CPG.0 range of Ormazabal's CPG system is made up of a full assembly of modular cubicles of up to 24 kV / 2500 A and up to 36 kV / 1250 A, GIS type, with SF6 insulation, for the configuration of different primary distribution electrical diagrams. Types of functional units: • Circuit-breaker CPG.0-V • Busbar coupling CPG.0-C • Disconnector CPG.0-S • Fuse protection CPG.0-F • Busbar rise CPG.0-RB The installation of elements that allow to...

Gas insulated, single busbar cubicle range Up to 24 kV / Up to 36 kV CPG System Medium Voltage Switchgear Primary Distribution Construction characteristics The CPG.0 cubicles present an architecture divided into independent compartments: D B • (A) Switch compartment. • (B) Busbar compartment. • (C) Cable compartment. • (D) Control compartment. • (E) Operation interface Its structure is made up of a metal frame with a mechanical rigidity that preserves the shape of the assembly under normal service conditions. The frame, together with the rest of non-live metal parts of the cubicle, is...

Gas insulated, simple busbar cubicle range Up to 24 kV / Up to 36 kV CPG System Medium Voltage Switchgear Primary Distribution The cable compartment, which allows frontal access to the medium voltage cables, is located in the lower part of the cubicle and has a cover that is interlocked with the earthing circuit. The external cone-type bushings allow the installation of toroidal-core current transformers on them. This compartment can be supplied ready to withstand an internal arc in terminals of 25 kA / 1 s, in compliance with the criteria of standard IEC 62271-200. The base can house the...
