电气线路的绝缘好坏,直接影响到设备的使用和用电安全。暗敷设的电气线路和在潮湿的建筑物内电气线路绝缘的好坏,更是一项重要的问题。按照工程性质划分,凡室内相对湿度接近于100%(即在室内的天花板、墙壁、地面及物体表面经常覆有一层湿气)者,称为特殊潮湿的建筑。1973年8月我们所承担的某项重点工程就属于这一类建筑。当时正值雨季,工期又不能延长,因此电气线路必须进行绝缘处理。根据供电部门和电气规范的要
The insulation of the electrical circuit has a direct impact on the use of the equipment and the safety of electricity usage. It is an important issue that the electrical wiring of the dark laying and the insulation of the electrical circuit in the wet building are good or bad. According to the nature of the project, where the indoor relative humidity is close to 100% (that is, the interior of the ceiling, walls, ground and objects are often covered with a layer of moisture), it is called a special damp building. In August 1973, we undertook a major project that belongs to this type of building. At the time of the rainy season, the duration could not be extended, so the electrical lines must be insulated. According to the power supply department and electrical specifications
