\u00a701 \u2014 WHAT IT IS<\/p>\n

Prefabricated branch cable: the branch joint is made in the factory, not on the site.<\/h2>\n

Prefabricated branch cable (YFD \/ YFDZ) is a feeder cable with premoulded branch joints fitted at fixed intervals along the main cable. The main conductor continues uninterrupted through the joint; the branch conductor is crimped to it and the whole assembly is re-insulated and re-sheathed in the factory under controlled conditions. On site the electrician only has to land the branches \u2014 no jointing, no heat-shrink work, no fire-watch permit at height.<\/p>\n

The alternative is making branch joints on the building face: a tray scaffold, an open flame or a crimping press, and a joint whose quality depends on whoever made it that morning. A factory joint is made once per design, tested, and then repeated identically for every floor.<\/p>\n

\n
FACTORY<\/div>

Made once, repeated identically<\/h3>

Branch positions are fixed from the floor plan. Every joint gets the same crimp, the same insulation and the same mould, then a routine test before dispatch.<\/p><\/div>\n

SITE<\/div>

Landing only, no jointing<\/h3>

The electrician lands the branch into the distribution board. No conductor work at height, no hot work permit, no weather window to wait for.<\/p><\/div>\n<\/div>\n<\/div><\/div>\n\n

\u00a702 \u2014 WHERE IT EARNS ITS COST<\/p>\n

High-rise risers and commercial feeders.<\/h2>\n\n
\u0627\u0644\u062a\u0637\u0628\u064a\u0642<\/th>Why prefabricated branch wins<\/th><\/tr>\n
High-rise residential risers<\/td>One main cable from the switchboard to the roof, with a branch at each floor’s distribution board. Site jointing on every landing disappears.<\/td><\/tr>\n
Shopping centres and towers<\/td>Long vertical runs with many tap-offs; the moulded joint keeps the route straight through the riser shaft.<\/td><\/tr>\n
Industrial plants<\/td>Feeder to several process buildings from one run, branches landed at each intake.<\/td><\/tr>\n
Infrastructure and metro<\/td>Constrained shafts and walkways where site jointing space and fire-watch are hard to arrange.<\/td><\/tr>\n<\/table>\n

The saving is not in the cable price. It is in the site hours, the scaffold time and the test reports that no longer depend on weather or access.<\/p>\n<\/div><\/div>\n\n
