Products for the cabinet as a whole assembly structure, main frame using KF-type structure, high precision, high strength, this structure is based on the modulus E = 25mm design, installation (assembly) joins convenient and flexible. Cabinet dimensions conform to IEC standards and requirements of the relevant national framework with KF profiles, U-shaped beam, bolt and nut plates linked together. When the main busbar rated current less than 4000A, the main frame KB profiles can also be used to U-shaped beam, bolt and nut plates linked together, can also be made of aluminum alloy connecting links. If the unit is in line with 25mm and 20mm geometry modulus common point (100mm, 200mm ...... etc.) can also be used KS FA profiles and profiles (two profiles is 20mm modulus). Using these profiles will not reduce the mechanical and electrical properties of its products.

Install the operating various function rooms are isolated, isolation rooms are divided into functional unit room, bus room, cable room. The role of independent compartments. According to user needs, design separate form: Form 1, Form 2a, form 3a, form 4a, form 4b. The main features of a main frame, the device adopts 8MF steel and special fittings assembled, large steel cross-sectional area, there is sufficient stiffness, the combination is simple, strong technology, good stability properties, Notes
