Overlegenheden ved kabler før grenet afspejles hovedsageligt i følgende aspekter:
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 påvirket, når væggen rystes, hvilket gør den særlig velegnet til bygninger, der skal modstå jordvibrationer .
Installationsfleksibilitet: Kabler inden for gren kan lægges i luften eller horisontalt begraves i henhold til brugerkrav . De har lavt installationsmiljøkrav og er lette at installere . dens tilladte bøjningsradius er relativt lille, hvilket reducerer installationsbesværet .}
