38kV switchgear for transformer substations in wind farms.

DVCAS is a modular, customizable gas-insulated switchgear solution for transformer protection and as an RMU in wind farms. This reliable UL listed product line is arc resistant, providing maximum protection for operations personnel.

  • Features

    DVCAS switchgear is built as compact function groups, made up by a combination of switchgear modules. Each module consists of an operating mechanism and relay compartment, an MV cable compartment, a stainless steel, gas-tight tank which uses SF6 gas to insulate the vacuum circuit breaker, busbar system, and integrated 3-position grounding switch. The combined modules are installed on a metal base frame, which allows for the group to be dropped in place as a single unit.
