Features
1. Divided into: receiving cabinet, busbar contact cabinet, feeder cabinet, motor control cabinet, reactive power compensation cabinet, lighting distribution cabinet.
2. The cabinet frame is assembled by partial welding of 8MF cold-formed steel, and there are installation holes arranged according to the modulus of E _ (20) mm and E _ (100) mm, respectively. In order to improve the versatility of product assembly.
3. NK type busbar clamped by thermoplastic molding of high flame-retardant PPO material is a block type binding structure with high mechanical strength and insulation.
4.1000mm and 1200mm wide cabinets, The front side adopts the symmetrical double-door structure of 600mm and the cabinet of 800mm width adopts the whole door structure, and the back of the cabinet adopts the symmetrical double-door structure of the cabinet structure which is not mounted against the wall.
5. The cabinet door is connected with the frame by galvanized rotary shaft hinge, which is easy to install and disassemble. Rubber inserts are arranged at the folding edge of the door.
6. The grounding knurled screw structure is used between the mounting parts in the cabinet and the frame to form a complete grounding protection circuit.
7. The top cover of the cabinet body can be removed when necessary, so as to facilitate the assembly and adjustment of the main master line.
