Shelves devices can be connected by welding or screw assembly. Shelves and housing should have sufficient mechanical strength and stiffness, power distribution box outlets, should be able to withstand the short-circuit of the installed components and the resulting mechanical and thermal stresses, Nankai distribution box, and should consider to prevent constituted sufficient to cause a large vortex loss of the magnetic path. While not due to equipment lifting, transportation and other conditions affecting the performance of the device. In order to ensure corrosion protection, power distribution box customized equipment should be corrosion-resistant materials or exposed surfaces coated with anti-corrosion layer, while also considering the use and maintenance conditions. 1) distribution box applications noncombustible material. 2) the risk of electric shock small production sites and offices, install open-type distribution board. 3) the risk of electric shock or poor operating environment large processing plant, casting, forging, heat treatment, boiler room, woodworking room and other places, enclosed cabinet should be installed. 4) conductive dust or flammable gases generated hazardous workplace must be installed closed or explosion-proof electrical facilities. 5) distribution box various electrical components, instruments, switches and lines should be arranged in neat rows, installation firm, easy to operate; cabinet (box) should be no dust, water and debris inside. 6) The cabinet floor installation (BOX) should be higher than the bottom surface of the ground 50 ~ 100 mm; operating handle center height is generally 1.2 ~ 1.5m; no obstructions in the range cabinet (box) in front of 0.8 ~ 1.2m. 7) protection cable reliable. Outside 8) cabinet (box) shall not have bare charged body exposed; it must be installed in the cabinet (box) or the outer surface of the electrical components of the power distribution panel, must be a reliable screen protection.
