Detailed introduction of cable branch box
Box shell The material is usually metal, such as stainless steel, cold-rolled steel plate, etc. These materials have good mechanical strength and can withstand a certain degree of external impact, protecting internal components from damage. For example, cable branch boxes with cold-rolled steel sheet shells can effectively resist collisions, compressions, and other situations that may occur on construction sites or in outdoor environments. At the same time, the outer shell of the box has sealing properties, which can prevent dust, moisture, and corrosive gases from entering the box. When used outdoors, its protection level generally reaches IP30 or above. Cable branch boxes with IP33 protection level can resist the intrusion of rainwater and dust, ensuring that internal electrical components work in a relatively clean and dry environment and extending their service life.

Maintenance steps for distribution cabinets
Preparation before maintenance Collect information Inquire with the operator about the situation of the distribution cabinet malfunction, including the time and symptoms of the malfunction (such as whether there is smoke, odor, abnormal sound, indicator light status, etc.). Check the operation records of the distribution cabinet to understand its recent load situation, whether there have been frequent trips, and other information.

Focusing on Energy Efficiency: Three level Energy Efficiency Transformers, the Energy saving Foundation of Power Systems
According to relevant national standards, such as GB 20052-2020 "Energy Efficiency Limits and Grades for Power Transformers", the energy efficiency grades of transformers are divided based on indicators such as no-load loss and load loss. Specifically, by measuring and calculating the no-load losses (losses in the iron core of transformers under no-load conditions, mainly related to the iron core material, magnetic flux density, etc.) and load losses (losses caused by resistance and stray losses caused by leakage flux in the winding when the transformer is running under load) of transformers with different capacities and voltage levels, and comparing them with the corresponding values specified in the standard, the energy efficiency level can be determined.

NCE Platform: Challenges and Responses Faced by Power Transformers
On July 30th, power transformers are usually equipment that people pay little attention to unless they malfunction, causing a disruption in household or commercial electricity consumption. In this case, the power is usually restored quickly, indicating that there is no problem with the transformer itself. For some transformers that are severely damaged and cannot be repaired, the replacement process takes longer. The NCE platform believes that the current supply chain bottlenecks and surge in demand are exacerbating the tight supply of transformers.
