To make a 1kv four-core heat shrinkable cable head, you need to follow the steps below:
1.Have relevant tools ready, including wire strippers, insulating tape, markers, etc.
2.Cut off the outer plastic layer of the cable head with a knife and polish the part smooth.
3.The copper wire of the cable is wound with a wrapping tube and fixed with high-temperature tape to prevent loosening during the heating process.
4.Use a cold air or hair dryer to heat the sheath material, and when it softens, the excess can be removed, ensuring that the overall appearance is smooth and smooth. Be careful not to damage the wires inside. If necessary, a part of it can be cut off with a welding machine, leaving a suitable length. It is good to have a supporting thermal expansion mold).
5 After completing the above operations, it is also necessary to treat the joint part to ensure that there will be no burrs or parts, so as not to affect the use effect and life. 6 Next, it's time to seal. First, mark one end (at the end of the day) and cut the appropriate length of shrink film. ?Gently stretch the heat shrinkage by hand to a stretchable range and unfold evenly to maintain a certain tension insideThen mark the other side and stretch it out in the same wayAt the same time, use your hand to shape the coil of the protective layer (if necessary, wrap a single yarn first).And straighten it for joint treatment. 7 It's cutting and cooling! First, use scissors to cut off a quarter of the stretch strip that has been stretched, put it on the pressure-sensitive tape, paste it into an axial shape according to the required length and size, and then use a utility knife to cut it from the center, it should be noted that the size of the incut must be controlled, so that the viscosity of easy reuse is intact; The semi-finished product is covered with dry and clean non-fibrous paper towels and left overnight to allow the temperature to drop rapidly and to obtain stress cushioning on the joints, so as to prolong the service life. It can also avoid cracking caused by environmental factors and enhance performance recovery. Please remember not to store for too long and keep it properly. (If there is oil stain, you can replace it with a new paper towel). Specifically, it can be combined with **tutorial to actually operate**.
The above information is for reference only, and specific construction safety also needs to be implemented in accordance with relevant electrical regulations and recommendations to ensure quality and safety of use. For special circumstances, if you encounter difficulties, you can also seek the help of personnel to ensure the smooth completion and subsequent normal operation and maintenance work.
