结构特点 /Structural features

箱体结构分立式和卧式，外壳采用 2mm 优质不镑钢板经多重折边工艺弯制 ( 或采用蜂窝结构的不锈钢双夹层复合板，具有阻燃、环保、隔热、防凝露等性能 )，
采用特殊不锈钢焊接工艺，箱体成型后整体强度高，表面光洁如镜，不留焊缝痕迹；内部安装梁 ( 板 ) 为热镀锌工艺处理，确保二十年内不锈蚀；箱体前后开门，
便于用户操作和检修，门四周镶有高 弹力耐老化密封胶条，每扇门均装有明暗两种门锁，明锁配有防堵防锈的遮雨罩；计量室全封闭带铅封装置；箱体侧
面装有防雨防异物的进线电缆穿管，底部冲有通风孔和电缆出线孔，顶部设有通风道和丝网，具有防水、防锈、防尘、防异物的功能，防护等级：IP54。
The box structure is divided into vertical and horizontal type. The outer shell is made of 2mm high-quality non-pound steel plate and bent by
multiple hemming process (or stainless steel double-layer composite board with honeycomb structure, which has the properties of flame retardant,
environmental protection, heat insulation and anti-condensation. ), using special stainless steel welding process, the overall strength of the box is
high, the surface is as clean as the mirror, leaving no trace of weld; the internal installation beam (plate) is treated by hot-dip galvanizing to ensure
no corrosion within 20 years; Open the door for easy operation and maintenance. The door is surrounded by high-elastic anti-aging sealing strips.
Each door is equipped with two kinds of door locks, light and dark. The lock is equipped with a rain cover for anti-blocking and rust prevention.
Lead sealing device; the cable side of the box is equipped with rain-proof and foreign-proof incoming cable, the bottom is flushed with ventilation
holes and cable outlet holes, and the top is provided with ventilation ducts and screens, which are waterproof, rust-proof, dust-proof and foreign-
proof. Function, protection level: IP54. L
