What are the installation requirements for the distribution cabinet base?
The installation requirements and specifications for the distribution cabinet base are as follows:
1. The distribution cabinet base should be made of channel steel no smaller than No. 10 and firmly connected to the repeated grounding network.
2. The distribution cabinet base should be equipped with cable trenches that can accommodate all cables.
3. The distribution cabinet base should be stable and firm, maintaining a certain distance from the building to facilitate operation and maintenance.
4. The grounding resistance of the distribution cabinet base should meet specification requirements.
The following are detailed explanations and examples:
Materials and connection methods of the distribution cabinet base
The distribution cabinet base should be made of channel steel no smaller than No. 10 to ensure its strength and stability. At the same time, the base should be firmly connected to the repeated grounding network to ensure the safety of the equipment during normal operation. The grounding network setup should comply with relevant standards, and the grounding resistance value should not exceed 4 ohms.
Installation of cable trenches
The distribution cabinet base should be equipped with cable trenches to accommodate all cables. The size of the cable trenches should be designed according to actual needs and consider possible future expansion. Additionally, drainage measures should be installed inside the cable trenches to prevent water accumulation from affecting the equipment.
Stability of the distribution cabinet base
The distribution cabinet base should remain stable and firm to avoid shaking caused by vibration during equipment operation. Meanwhile, the base should maintain a certain distance from the building to facilitate operation and maintenance. If conditions limit maintaining this distance, appropriate protective measures should be taken.
Grounding resistance requirements
The grounding resistance of the distribution cabinet base should comply with relevant standards to ensure
