Description
Solid-insulated switchgear MSIS49-12 series represents a breakthrough in switchgear technology, embodying a fully insulated, fully sealed, and maintenance-free approach to solid insulated vacuum switchgear.
Engineered with high-voltage components encapsulated in epoxy resin — a material known for its superior insulation properties — this design integrates the vacuum interrupter, main conductive circuit, and insulating support into a cohesive unit.
The functionality MSIS49-12 units are interconnected via a fully insulated solid busbar, ensuring that the switchgear’s performance is impervious to external environmental conditions. This guarantees the reliability of the device’s operation and the safety of the operator.
The MSIS49-12 series stands out for its comprehensive insulation, sealing, and shielding qualities. These features render it exceptionally fit for environments that challenge traditional switchgear, including high altitudes, extreme temperatures, humid conditions, severe cold, and heavily polluted areas. Thus, it offers a reliable and safe solution for the reception and distribution of electrical energy across various settings.
