Aluminum Alloy Cable · Product Introduction

Aluminum alloy cable is a new type of power cable using AA8000 series aluminum alloy (such as AA8030, AA8076) as the conductor, manufactured through special compact stranding and annealing processes. It typically uses cross-linked polyethylene (XLPE) as insulation and polyvinyl chloride (PVC) or polyolefin as the sheath. It is not a "pure aluminum cable," but rather aluminum alloyed with copper, iron, magnesium, rare earth elements, etc. While retaining the advantages of aluminum being "lightweight and inexpensive," it significantly improves the critical shortcomings of pure aluminum—poor creep resistance, loose connections, and susceptibility to fracture—making it the leading "aluminum-for-copper substitution" product in low-voltage power distribution.

Model	Name	Installation Application
YJLHV	XLPE insulated PVC sheathed aluminum alloy power cable	Cable tray, conduit, indoor and outdoor fixed installation
YJLHV22	Steel tape armored aluminum alloy power cable	Direct burial, compression-resistant applications
YJLHV62	Aluminum alloy interlocked armored aluminum alloy power cable	Surface mounting without cable tray, eddy current prevention
YJLHV72/73	Steel wire armored aluminum alloy power cable	Vertical installation, long-span applications
ZR-YJLHV	Flame-retardant aluminum alloy power cable	Locations with building fire protection requirements
WDZ-YJLHV	Low-smoke zero-halogen flame-retardant aluminum alloy power cable	Subways, hospitals, high-rise buildings and other densely populated areas
VLHV	PVC insulated aluminum alloy power cable	Low-voltage power distribution
