用途 Application
預制分支電力電纜可在住宅樓、辦公室、賓館、醫(yī)院、商場等高層建筑使用，而且已擴展到公路、橋梁及隧道照明燈其它領域。預制分支電力電纜作為一種新型建筑用線，是工廠按照用戶要求的主、分支電纜型號、截面、長度及分支位置等指標，經(jīng)過專業(yè)的一系列設備、生產(chǎn)流水線將其完成的帶分支的電纜。
The prefad branch electrical power cable can be wildly applied to the tall buildings:dwelling house buildings,office buildings,guesthouses,hospital markets and so on,but also has expanded to the other realm:highway,bridge and tunnel illumination and so on.As a new type of building cable,prefad branch cables are produced according to the targets of consumer’s demands:type of the main and the branch cable,cross section,length and branch position,they are finished on the assembly line in the factory where the worker use a series of special purpose equipments .
產(chǎn)品特性 Product features
