Boffetti - Model HICOS DVB -Gas Insulated System for Secondary Distribution
The HICOS DVB gas-insulated system is designed for secondary electrical distribution, integrating a vacuum circuit breaker with a three-position disconnector in a single compact unit. This system uses vacuum interrupters and places both components in a sealed, gas-filled stainless steel container. The gas serves as the insulation for live parts, allowing for a reduced footprint with unit compartments as narrow as 375 mm. Such a design is beneficial for constructing air-insulated switchgear (AIS) and medium voltage/low voltage (MV/LV) transformer substations. The HICOS DVB system is versatile, suitable for installation in panels by third-party manufacturers, and is widely used across various sectors including renewable energy, utilities, industries, and infrastructure projects such as rail transport and airports. Tested at CESI and approved by Enel GSCM005, this system adheres to IEC standards and maintains a patent pending status.
Gas insulated integrated system with vacuum circuit breaker, three position disconnector, current and voltage sensors, for secondary distribution. Tested at CESI according to IEC Standards. Enel GSCM005 approved. Patent pending.
The HICOS DVB systems integrate in a single apparatus the functions of circuit-breaker and three-position disconnector (open-closed-earth). The two apparatus are arranged in a sealed stainless steel container filled with gas. The circuit-breaker is made with the use of vacuum interrupters. The contacts of the disconnector are isolated in the gas. The gas constitutes the insulation of the live parts. The dimensions are very small and allow the construction of unit compartments with a minimum width of 375 mm.
DVB systems are normally used in HICOS AIS secondary distribution air insulated switchgear, for the construction of electrical distribution and MV / LV transformer substations. They are also available for installation in third-party manufacturers’ panels. They are widely used in distribution networks for: renewable energy, utilities, light industry, oil & gas, chemical plants, water treatment, data centers, rail transport, airports, infrastructures, shopping centers, service sectors, etc.
