Requirements for the distance of distribution boxes and switch boxes from the ground
The distance between the distribution box and the switch box should not exceed 30 meters, and the horizontal distance between the switch box and the fixed electrical equipment it controls should not exceed 3 meters. This proximity principle reduces line losses and improves power supply efficiency. Electric equipment shall be free from recognized hazards that are likely to cause death or serious physical harm to employees. Generally, distribution boxes can be divided into three levels of secondary protection, that is, three levels of distribution boxes: general. The principle of minimizing distribution distances means that the distances between distribution boards and switch boxes should be kept as short as possible.

Analysis of the causes of cracking in outdoor power distribution boxes
Abstract: The temperature gradient and mismatching between the thermal expansion of the core and flange readily lead to cracks and discharges on the core surface of the dry-type valve-side bushing, which severely impact the safety of power systems. ABSTRACT: Predicting the occurrence of failures in power grids through specific outage risk predic-tors is a primary concern for utilities nowadays. Wooden poles represent core items to focus on in this process. Most substation equipment consists of metal components made from various materials such as pure copper, carbon steel, and stainless steel. This fracture is not accidental but the result of multiple factors. This phenomenon can be understood from two perspectives: the. The reasons for corrosion cracking of secondary cable joints used in outdoor terminal boxes of a 220 kV substation in humid environment were investigated by scanning electron microscopy (SEM), X-ray diffractometer (XRD), infrared spectroscopy (IR) and ion dissolution test.
