Installation requirements for distribution cabinet bases may vary depending on the specific design and application of the cabinet. When installing our switchboard cabinets, it is important to follow Shouke® manufacturer's instructions as well as local installation standards.
The installation requirements and specifications for the base of the distribution cabinet are as follows:
1. The base of the distribution cabinet should be made of no less than 10 # channel steel and firmly connected to the repeated grounding grid.
2. The base of the distribution cabinet should be equipped with cable trenches and able to accommodate all cables.
3. The base of the distribution cabinet should be stable, firm, and maintain a certain distance from the building for easy operation and maintenance.
4. The grounding resistance of the distribution cabinet base should meet the specification requirements.
Here are detailed explanations and examples:
The material and connection method of the distribution cabinet base
The base of the distribution cabinet should be made of no less than 10 # channel steel to ensure its strength and stability. At the same time, the base should be firmly connected to the repeated grounding grid to ensure the safety of the equipment during normal operation. The setting of the grounding grid should comply with relevant specifications, and the grounding resistance value should not exceed 4 ohms.
Installation of cable trenches
The base of the distribution cabinet should be equipped with cable trenches to accommodate all cables. The size of cable trenches should be designed according to actual needs, and possible expansion needs in the future should be considered. At the same time, drainage measures should be set up in cable trenches to prevent water accumulation from affecting equipment.
Stability of distribution cabinet base
The base of the distribution cabinet should be stable and firm to avoid instability caused by vibration during equipment operation. At the same time, the base should be kept at a certain distance from the building for easy operation and maintenance. If conditions limit and it is not possible to maintain a certain distance, corresponding measures should be taken for protection.
Requirements for grounding resistance
The grounding resistance of the distribution cabinet base should meet the regulatory requirements to ensure the safety of the equipment during normal operation. The specific value of grounding resistance should be calculated based on factors such as equipment capacity and grounding method, and should comply with relevant specifications.
In short, the installation requirements and specifications for the base of the distribution cabinet are to ensure the safety, stability, and operability of the equipment during normal operation. In practical operation, design and construction should be strictly carried out in accordance with regulatory requirements to ensure the safe and reliable operation of equipment.
