Pre-zināšanas kabeļu pārākums galvenokārt atspoguļojas šādos aspektos:
Excellent seismic resistance, air tightness and water resistance: The branch joints and the upper support heads of the pre-branch cables are all molded in the factory with polymer materials, which have good air tightness and water resistance. It can supply power and operate normally even in a humid environment, and can be laid both outdoors and underground. The specially designed seismic structure ensures that the joints are not ietekmē, kad siena tiek satricināta, padarot to īpaši piemērotu ēkām, kurām ir jāizturas pret zemes vibrācijas .
Installation flexibility: Pre-branch cables can be laid in the air or horizontally buried as per user requirements. They have low installation environment requirements and are easy to install. Its allowable bending radius is relatively small, which greatly reduces the installation difficulty.
