Underground cables are simply cables that would normally be hung on utility poles, but instead, they’re buried in the ground.
You can think of them as the “blood vessels” beneath the city. Before, when we looked up, all we saw were “spider webs,” but now, for aesthetic reasons and to protect against wind and rain, people simply dig trenches and lay pipes underground to stuff all the electrical and network cables inside.

In the underground cable industry, the biggest fear isn’t buying something too expensive, but rather problems arising after burial.

Cables buried several meters underground, if a fault occurs due to quality issues, the labor and machinery costs involved in locating the break, re-excavating, backfilling, and repairing often exceed the cable’s price in terms of both labor and machinery. Not to mention the delays and breaches of contract caused by power outages.

As a directly-owned factory in China with years of experience in this field, we understand our customers’ true concerns.

Our core solutions address:

• “Die in the light” and “Rotten in the ground”: Many underground cables perform well in laboratory tests, but in the complex underground environment, facing acid and alkali corrosion, groundwater immersion, and termite infestation, the insulation layer ages very quickly. We have specifically strengthened radial and longitudinal water-blocking technologies to ensure stable operation for decades even in humid or flooded environments.
• Mechanical damage risk: The complex construction environment, with rocks in the backfill soil and pressure from settlement, is a major cause of cable breakage. Our steel strip and wire armor layers are not just “wearing a vest,” but also feature redundant structural strength designs to withstand complex geographical pressures.
• Delivery pitfalls: Many suppliers offer low prices, only to find the specifications are reduced upon delivery. As a factory, we support full-process traceability. Accurate specification labeling and genuine material substitution are our bottom line for survival in this industry.

Why choose us instead of other suppliers?

• True “factory price” does not mean sacrificing quality: We have a complete supply chain in the underground cable industry, allowing for lower costs through bulk raw material procurement. We invest the savings in factory testing. Every reel of cable undergoes rigorous partial discharge and withstand voltage tests to ensure customers receive quality products.
• Understanding standards, and even more so, understanding real-world needs: We not only meet IEC or national standards but have also witnessed countless construction sites. We will provide the most suitable model recommendations based on your laying geological conditions (saline-alkali land, swamp, or rock layer), avoiding over-design and wasted money, as well as under-design and potential hazards.
• Speed ​​response: On-site delivery is a common occurrence. Our production scheduling system is highly flexible, allowing for rapid response to urgent orders and ensuring your project isn’t delayed by cable delivery issues.
