Basic Information
Description
Designed for the installation of low-voltage distribution, switching, and protection equipment; Distribution busbars: copper or aluminum; Switching devices intended for line switching and protection against overloads and short circuits; The switchgear consists of a series of electrical distribution cabinets manufactured according to the client’s project documentation and are interconnected by upper busbars in the specified order and quantity; Service is one-sided, but two-sided service cabinets can be produced upon agreement with the user; Cabinets are installed in enclosed, switchgear-designated rooms such as substations, industrial buildings, etc.
Enclosure:
Cabinet enclosures are made from hot-dip galvanized profiles and DX51D+Z275 sheet steel, with a thickness of 1–2 mm. They are painted with standard RAL7032 color (other colors can be applied according to the project). The cabinets are connected to each other using connection bolts. The cabinet enclosures are constructed from hot-dip galvanized profiles and sheet steel. These are assembled structures with surfaces coated in durable powder coating. Doors have hinges, and locks are made of stainless steel. The cabinets are prepared for interconnection and feature lifting lugs. Current and voltage measuring instruments and control buttons can be mounted on the doors. Automatic circuit breakers and fuse-switch blocks can be installed inside the cabinet or positioned so that their front parts and control handles are on the outer side of the cabinet doors.
