Standard practice for high-voltage ring main unit cable heads
1. Preparations.
Before the production of high-voltage ring main unit cable heads, the following preparations need to be made:
1.Prepare the tools and materials you need, including cable heads, insulation, screws, and more.
2.Check whether the specifications and models of the cable head meet the requirements, and check the quality of the cable head to ensure that there are no defects.
3.Prepare the workspace and make sure it is dry, tidy and free of flammable materials.
Second, the production process.
The manufacturing process of the cable head of the high-voltage ring main unit is as follows:
1.Fix the cable head on the ring main unit and ensure that the cable head is firmly connected with the ring main unit.
2.Strip the cable to expose the core and check that the length of the core meets the requirements.
3.Connect the core wire with the cable head, and wrap it with insulating material after the connection is firm to ensure good insulation.
4.Fix the cable head on the ring main unit, and make sure that the cable head is firmly connected with the ring main unit.
5.Test the cable head to make sure it is working properly.
3. Precautions.
When making the cable head of the high-voltage ring main unit, the following matters need to be paid attention to:
1.Make sure that the specifications and models of the cable heads meet the requirements, and check the quality of the cable heads.
2.Keep it clean during the production process to avoid contamination by dust and impurities.
3.When connecting the core wire, pay attention to the firm connection to avoid loosening or falling off.
4.When wrapping the insulating material, it should be uniform and tight to ensure good insulation.
5.When testing the cable head, it should be carried out in accordance with the prescribed method to ensure that it works properly.
In a word, the standard practice of the cable head of the high-voltage ring main unit needs to be carried out in accordance with the prescribed steps, paying attention to safety matters to ensure the quality and safety performance of the cable head.
