Product Overview ZBW0.69 / 40.5 modular substation series are the 35KV substation equipment dedicated for wind power generation, developed based on the digestion and absorption of advanced technology and production processes, to meet the growing need for wind power generation. The new product of our company - metal shell substations adopt aluminumcoated zinc platesheets and electrostatic spraying process for the boards, whose mechanical strength and anti-corrosion effect are greatly improved; therefore, the products are especially suitable for wind farms with the damp environment and heavy winds. The sheet metal is processed and assembled by CNC machine tools to ensure the accuracy of the connections, compact structure, convenient and flexible assembly and processing. The stainless steel hinge allows the doors to be opened and closed more flexibly. The elastic structure is adopted, to achieve good windproof effect. The automatic return device of the lock allows the door to be opened and closed with ease. The top is of the double-decked structure which is beautiful and generous. It also strengthens the such functions as rainproof, heat insulation, heat preservation and anti-condensation. The top can be hoisted through simple operation, which is convenient for the maintenance and upgrading of high and low voltage equipment and transformers. The housings can also be made of non-metallic materials, (cement, composite materials, but they are inferior to the aluminum coated zinc plate housing in the aspects of mechanical strength and corrosion resistance, and the structural flexibility is very low.) The bottom adopts channel steel and angle steel assembled through integralwelding, featured by high strength, small deformation, easy handling; DACROMETanti-corrosion treatment is used, whose corrosion resistance is comparable with that of hot-dip galvanizing.
