Underground wires are electrical wires buried underground.The overhead wires we usually see hanging on utility poles and swaying in the wind are called overhead wires; while underground wires are wires that are specially “armored” and buried in the ground because the outside world is too messy and dangerous.

Once wires are buried underground, the biggest fear isn’t damage itself, but not being able to find where the damage occurred.

Anyone in the underground wire construction business knows that the wire itself isn’t expensive; the real cost is the excavator and the labor costs of downtime. If the sheath is damaged, gets damp, or is eaten by termites, the cost of secondary excavation can wipe out the entire project.

We focus on two things when making underground wires: the sheath must be sufficiently robust, and the copper must be of high purity.

Many products on the market look identical, but a few micrometers thinner insulation layer will reveal the difference after three to five years buried in the ground. Our wires are specifically thickened for acidic or alkaline soils and humid environments, and even take into account the tensile forces of crustal subsidence.

Why order from us? Simply put, we are the source factory. This means you don’t have to pay the markup of traders, and most importantly, I can directly show you the inspection reports for every spool of wire. We don’t engage in misleading labeling; a 10 square millimeter wire will never be labeled as 9.2.

If your current supplier’s delivery time is unstable, or they keep having inexplicable after-sales problems, why not compare our sample line with your current one? Cut it open and take a look, and you’ll see where the difference lies.
