the difference between cold cable accessories and heat shrinkable cable accessories talked a lot in front of the cold shrink cable accessories and heat shrinkable cable accessories, the basic principle and some characteristics of today was cold cable head and heat shrinkable cable accessories by a comparison of the performance of: 1, the electric control: the difference between the cold cable head using geometrical stress cone to control electric field; Heat shrinkable cable accessories using thermal shrinkage stress tube to control the electric field. 2, making the difference of raw materials: use of the raw materials of cold shrink cable head is silicone rubber; Use of raw material is PE heat shrinkable cable accessories. 3, the structure of the cable accessory constitute: the difference between the cold cable head will stress cone, outer insulation protection tube and umbrella skirt one; Heat shrinkable cable accessories using stress control tube, insulating protection tube, umbrella skirt separate production supporting construction, etc. 4, ground connection mode: the difference between the cold cable head using a constant force spring; Using ground need to welding heat shrinkable cable accessories. 5, contraction way: the difference between the cold cable head extracting core plastic article support the natural shrinkage; Heat shrinkable cable accessories need heat shrinkage; There are also some other difference, how to measure a good performance of the cable accessories? Such as cold cable head partial discharge quantity is small, the construction of the relatively small space requirement, installation speed slightly faster; Heat shrinkable cable accessories partial discharge is larger, the construction of the space requirements is bigger, the installation of the slower.
