The casing of a box type substation is an important component that not only protects internal equipment from external environmental influences, but also has certain aesthetic and environmental adaptability. Here are some detailed information about the casing of the transformer box:
Classification of Box Transformer Shell: The box shell of a box type substation is divided into 10, 20, and 30 levels, which means that the temperature rise of the transformer inside the shell exceeds the difference between the temperature rise measured outside the shell of the same transformer, such as 10K, 20K, and 30K.材料类型：Non metallic landscape box type transformer shell: Generally made of high-strength cement concrete as the raw material for the shell, it has the characteristics of strong plasticity and long service life.
Composite panel box transformer shell: The surface is made of various composite panel materials such as PVC, high-strength alloy, galvanized, and aluminum zinc coated sheet. It is lightweight and highly corrosion-resistant, but may undergo chemical reactions over time leading to embrittlement.
Carved board box transformer shell: The exterior is a high-quality color embossed decorative metal plate treated with a special layer, with a flame-retardant polyurethane insulation layer added in the middle. The base layer is an aluminum foil insulation layer, with a beautiful and atmospheric style.
Metal box transformer shell: It is mostly made of high-strength and corrosion-resistant metals such as galvanized sheet and stainless steel sheet, which have high structural strength and good heat dissipation performance. However, the insulation effect is poor and not suitable for humid and rainy areas.
Other new types of transformer housings: such as the use of DMC insulation material sheets for automotive bumper materials for transformer housings, with structural safety and insulation protection; A new type of non-metallic box transformer shell made of glass cement material; Use brightly colored steel plate composite box transformer shells for insulation and heat preservation.设计理念：变压器箱体的外壳设计应兼顾实用性、美观性和环境适应性，考虑气候条件、地理特征、电磁干扰等因素，保证有效抵抗恶劣环境的同时与城市景观融为一体。制造工艺：随着智能制造技术的发展，变压器外壳的生产逐步向自动化、智能化转型，提高生产效率和精度。质量控制：从原材料采购、生产过程到成品检验，每个阶段都需要严格的质量控制措施，确保产品符合国家标准和客户要求。防腐技术：Made of stainless steel material and treated with corrosion-resistant powder coating process, effectively preventing rust and extending product service life.
In summary, the selection and design of the casing for the transformer box need to consider multiple factors to ensure its functionality, aesthetics, and durability.
