Cable quotations are easy to compare because the price is printed on one line. Installation cost is scattered across drum handling, labour, bends, trays, conduit, terminations and the time it takes to work around other trades.
For a China ACWU90 Cable Manufacturer, the more useful comparison begins when the cable route is put beside the quotation.
Tengyuetong’s YJLHVS2 / ACWU90 rare-earth aluminum alloy cable uses aluminum-alloy interlocked armour. The product is intended for dry or damp locations and is designed to provide mechanical protection without a conventional steel-tape structure.
Try the bend on the route drawing
The product data gives a minimum bending radius of seven times the cable outside diameter. Mark that radius at the actual corners, risers and terminations on the drawing.
A cable can be flexible in a sales demonstration and still be awkward when the installer has to turn it behind switchgear with limited clearance. Discovering that after drums arrive is expensive.
Weight also affects the job. Rare-earth aluminum alloy conductors have a lower density than copper, but an aluminum-alloy cable is not selected as a same-size substitute for copper. Ampacity, voltage drop, short-circuit duty and installation method still set the conductor size.
Guangdong Tengyuetong Cable produces rare-earth aluminum alloy power cables in several structures and voltage classes, including interlocked armoured designs and copper-aluminum transition products.
The connection is where installers can lose the advantage
Terminations deserve their own method statement. Compatible lugs, conductor preparation, tightening torque and thermal cycling all influence long-term contact resistance.
If a project is switching from copper practice to aluminum-alloy cable, do a sample termination with the actual installer and hardware before the main installation starts. It is a cheap way to find tooling or training gaps.
For cost comparison, put material price, cable weight, support system, conduit or tray requirements, pulling labour and termination hardware in one sheet. The difference between copper and ACWU90-style cable then becomes a project calculation instead of a slogan.
Record the route assumptions and installation items included in each quotation. When the layout changes, review that same list with the installation team so the comparison does not rely on an outdated plan.
That calculation will vary from site to site. That is exactly the point.
