YBW-40.5/0.69-4000 Energy box-type Prefabricated Substation

Product Overview:

• The box transformer is divided into three parts: high-voltage room, low-voltage room and transformer, arranged in the shape of a “目”. Except for the transformer heat sink and the body exposed outside the box, all other live compartments are sealed.
• In independent compartments. Each room is separated into independent compartments by partitions, and a manhole is provided inside the body for easy installation and maintenance.
• The inner and outer surfaces of the box are flat, without rust, coating shedding and bump damage. The coating layer is firm and uniform, without obvious contrast reflection.
• The box base and all exposed metal parts are treated with anti-corrosion and anti-rust treatment, and a durable protective layer is sprayed.
• The box top cover is equipped with a rainproof sealing cover and rainproof eaves, and the double-layer box top cover can prevent heat radiation.
• The design size of the box transformer door matches the size of the installed equipment. The box transformer door adopts an internal hinge, and all doors on the box open outwards with an opening angle greater than 90°.
• The box is made of stainless steel, and the paint is imported car paint. All are baked paint, which is smoke-proof, heat-proof, mildew-proof, and has strong outdoor weather resistance.
• The area where the photovoltaic power station is located has low temperature, large temperature difference, high humidity, and much wind and sand. The box transformer has a reasonable protective structure, dustproof structure and low temperature resistance, which can meet the requirements of normal and safe operation under harsh environmental conditions.
