Three 1kV YJV-3*50+1*25 cables are connected together; how should the intermediate joint be made? Is it feasible to crimp it with copper tubing and then wrap it with high-pressure waterproof self-adhesive tape and insulating tape?
Basically, the described method is used, paying attention to the protection of the joints and testing whether the insulation meets the requirements.
Basically, the described method is used, which is a traditional approach in the absence of specialized materials. There are now specialized low-voltage cable connectors, and installation using heat-shrink tubing is relatively convenient.
Using low-voltage heat-shrink tubing yields good results, and the insulation performance is satisfactory.
Using heat shrink tubing yields better results; after completion, a voltage resistance test must be carried out, followed by wrapping with waterproof tape and then covering it with insulating tape. :)
The oil-blocking casing is crimped, and heat-shrink tubing is used for insulation; it’s easy to handle in low-pressure situations, and insulation isn’t a problem in such cases.
The traditional method involves using self-adhesive tape and waterproof tape in several layers; it takes 2-3 hours just to wrap the three ends at the joints. Now, in addition to heat-shrink tubing, there are also cold-shrink tubes for low voltage applications, which are convenient and fast. If you don’t know them, you can search for them on Baidu or Shoufujia.

It depends on your application environment and the duration of use – is it a temporary connection in a dry area, or long-term use in a supermarket setting? Of course, it’s best to use heat-shrinkable tape; self-adhesive tape, waterproof tape, and insulating tape can also achieve the same result, but it requires much more work: lol
