Comparison Of Cable Insulating Sleevings

Jul 16, 2017

                First of all, power insulation heat shrink in the wall thickness is medium thickness, to be slightly thinner than the casing, see Dasheng Company product specifications.Insulating Sleevings

                Second, the hot-shrinkable coating of the wall tube is hot melts, 75-caliber straight-coated, 75-caliber and above specifications using the spiral coating method, from the appearance of the difference is obvious, is a mechanical coating of the products, but the casing is usually hand-painted at both ends, can also be fully coated, the coating is the glue layer is cold glue, waterproof performance is inferior to the wall casing.

               Again because the gelatinize way is not the same, in general, the heat shrink in the wall tube to do the largest caliber is 200, and the heat shrink casing can do 300, mainly in the middle wall tube large caliber spiral coating equipment is more expensive. In addition, the two products of polyethylene substrate formulations are not the same, the middle wall tube material is softer.Insulating Sleevings

               Finally, due to the many differences, there are also many differences in the use of heat-shrinkable wall tubes and heat-shrinkable casing, which are mainly used in the middle connection of the cable, and can be used in other products such as automobiles, while the heat-shrinkable casing is basically used as the inner and outer sheath of the cable intermediate connection. At the same time, the hot shrinkage of the wall tube products abroad used more, the domestic market is not very large.Insulating Sleevings
