According to actual demands of users and valuable advice from related electric designers, Shenghua Cable Group has developed series products of three-phase four-wire and other multicore prefaicated branch cable on the basis of single-core prefabricated branch cable. They are minly applied to lighting and dynamic electricity of factory and middle/high buiding.
Because multicore cable has large outside diameter and heavy weight, after it is made to preset branch cable, the outside diameter will be larger and result in difficulty in laying. Therefore, the largest multicore prefabricated branch cable manufactured by our Group is restricted below 120 mm2. There are a variety of flame retarded type and fireproof type in equal or different section.
At present, the branch wire of multicore prefabricated branch cable can only be a grade section in a loop. If you adopt branch wire of different sections, you can choose single-core prefabricated branch wire. Current carrying capacity of multicore prefabricated branch cable is the same to that of multicore cable, and the installing method is similar to that of multicore cable. |
