Grounding flange is a component used in the fields of power equipment, electrical systems, etc. to achieve grounding connection function. Combining with the grounding flange in this picture, the following will introduce it to you:
Basic structure and appearance
These grounding flanges have a disc-shaped appearance, with a white body and some holes distributed on top. These holes are usually used for bolt installation and fixation to connect the grounding flange to other equipment components. At the same time, it also comes with metal connectors (such as copper components), which are used for electrical connection and grounding function.
working principle
The grounding flange is connected to the grounding wire through a metal connector. When the equipment experiences leakage or abnormal high voltage, the current can be introduced into the ground through the grounding flange, thereby ensuring the safety of the equipment and personnel. For example, in high-voltage electrical equipment, once the insulation is damaged, the fault current can quickly dissipate to the ground through the grounding flange, avoiding electric shock to personnel and further damage to the equipment.
Application scenarios
Power system: In GIS (gas insulated metal enclosed switchgear), grounding flanges are used to ground the equipment casing and ensure safe operation; Grounding flanges are also used at cable terminals, cable joints, and other locations to ensure the electrical safety of the cable system.
Industrial equipment: Some large industrial electrical equipment, such as large motors, transformers, etc., achieve reliable grounding of the equipment casing through grounding flanges to prevent equipment leakage and safety accidents.
Performance Requirements
Electrical performance: It has good conductivity to ensure that fault current can be quickly introduced into the ground and reduce grounding resistance. Generally, it is required that the grounding resistance be within the specified range, such as not exceeding a few ohms.
Mechanical performance: It has certain strength and corrosion resistance, and can withstand mechanical stress and environmental erosion during equipment operation. Because the grounding flange needs to be installed on the equipment for a long time, it needs to adapt to different environmental conditions, such as humidity, acidity, and alkalinity.

Why Regular Transformer Maintenance Matters: 5 Serious Consequences of Neglecting ItI. Allowable TemperatureWhen a transformer is in operation, its windings and iron core generate copper loss and iron loss. These losses are converted into heat energy, causing the temperature of the transformer's iron core and windings to rise. If the temperature exceeds the allowable value for a long time, the insulation will gradually lose its mechanical elasticity and age.The temperature of each part of the transformer during operation is different: the winding temperature is the highest, folRockwell09/12/2025 -
How to Implement Condition-Based Maintenance for Power Transformers? A Complete 4-Step Process Analysis1. Definition of Condition-Based MaintenanceCondition-based maintenance refers to a maintenance method where decisions on whether and how to perform maintenance are determined based on the real-time operating status and health condition of equipment. It has no fixed maintenance methods or schedules. The prerequisite for condition-based maintenance is the establishment of equipment parameters and the comprehensive analysis of various operational information of the equipment, so as to make reasonaNoah09/12/2025 -

High harmonics? Your transformer may be overheating and aging fast.This report is based on the analysis of one-day power quality monitoring data of your company's distribution system. The data shows that there is significant three-phase current harmonic distortion in the system (with a high total harmonic distortion of current, THDi). In accordance with international standards (IEC/IEEE), harmonic currents at this level have posed substantial risks to the safe, reliable, and economical operation of the power supply transformer, mainly manifested in additional hLeon09/12/2025 -
Ultimate Guide to AC Contactor Abnormal Noise: From Electromagnetic Noise to Mechanical Vibration, Accurate Diagnosis and HandlingIn electrical control systems, AC contactors are among the commonly used electrical components, and they are also a common source of various electrical faults. After long-term use—especially in harsh environments with high levels of dust—AC contactors may sometimes emit squeaking or rattling noises after being pulled in and held. The causes of this phenomenon are analyzed as follows.Squeaking Noise After Pull-In and HoldingA fully functional AC contactor makes no noise when energized and pulledFelix Spark09/11/2025
