Los Underground cable manufacturers They play an essential role in modern electrical infrastructure. With the growth of cities, The need for wiring solutions that are safe, durable and resistant to extreme environmental conditions has increased. In this article, We will thoroughly explore the world of underground cables, The main manufacturers, Its technologies, as well as a detailed guide by levels of strain: 11kV, 15KV Y 33KV.
What is an underground cable?
And underground cable It is an electric conductor designed to settle underground in order to transmit electricity without being exposed to the environment. These cables must have adequate protection against moisture, soil pressure, rodents and other factors. The main advantage against aerial cables is their discretion, Safety and lower long -term maintenance.

These manufacturers design their products to meet standards such as IEEE 404, ICEA S-93-639, and ANSI C119.
33KV Underground Cable Manufacturers: High voltage for large projects
When it comes to systems of 33kV, We are in the field of High underground voltage, used to transmit large electric charges from generation plants to regional substations.
33KV underground cable applications:
- Wind and Solar Parks
- Electrified rail systems
- Large -scale industrial areas
Typical construction:
- Dry XLPE insulation
- Internal and external semiconductor screen
- Steel wire armor or corrugated steel tape
- UV resistant outer layer and soil chemicals
Best cable manufacturers 33kv:
- ABB (NKT Cables) - Custom solutions for electric transmission infrastructure.
- Elsewedy Electric - One of the largest manufacturers in the Middle East and Africa.
- Tbea - Chinese manufacturer with strong international presence in high voltage cables.
- Dosense Cable - Reliable supplier for 33KV Aluminum and Copper underground cables, complying with IEC 60840.
Los 33KV Underground Cable Manufacturers They must guarantee a useful life of more than 30 years under demanding conditions, In addition to international certifications.
Types of insulation used by underground cable manufacturers
One of the most important aspects when choosing a manufacturer is the type of isolation you use. The most common are:
- XLPE (Crosslinked Polyethylene): Excellent for high voltage, Good thermal resistance.
- EPR (Etiileno propileno): More flexible, Ideal for difficult facilities.
- PVC (Polyvinyl chloride): Limited use, more common in low voltage.
Each manufacturer has its own formulation and extrusion technique for these materials.
Underground cable manufacturers in Latin America
Peru and Colombia
- Dosense Cable - International supplier with focus on three -phase underground cable, monkey and high voltage.
These manufacturers offer logistics services, Personalized engineering and local technical assistance.
Comparison between local and international manufacturers
| Criterion | Local manufacturers | International manufacturers |
|---|---|---|
| Costs | More competitive | Higher |
| Certifications | Regional | International (IEC, IEEE, etc.) |
| Delivery time | Faster | It can take longer |
| Technical support | In the local language | Sometimes alone in English |
| Variety of products | Limited | Wide |
A common strategy is to combine suppliers: local manufacturers for urgent deliveries, and international manufacturers for large -scale projects.
How to choose a reliable underground cable manufacturer?
1. Certifications and compliance with standards
Make sure they meet IEC, BS, Ieee o ansi.
2. quality tests
Request Routine Test and Test Reports (tipo AC withstand test, hot set test, etc.).
3. Delivery times
Fundamental in projects with tight schedule.
4. After -sales service
A good technical support makes a difference in complex facilities.
5. Experience in similar projects
Check what similar works have done.
Underground Aluminum Cable Manufacturers vs Copper
| Feature | Copper cables | Aluminum cables |
|---|---|---|
| Conductivity | Mayor | Smaller |
| Cost | More expensive | Cheaper |
| Weight | heavier | Light |
| Installation | More difficult | Easier |
| Service life | Slightly larger | Good if it is well installed |
Many manufacturers offer both options to adapt to the technical and budgetary conditions of the client.
Trends in the manufacture of underground cables
- Digitization: Cables with embedded sensors for thermal and cargo monitoring.
- Sustainability: Use of recyclable materials and eco -efficient processes.
- Nanotechnology: Improvement of dielectric properties of insulating materials.
- Smart cables: Integration with IoT to detect real -time failures.
Conclusion: What underground cable manufacturer choose?
Choosing an underground cable manufacturer depends on many factors: Type of tension (11kV, 15kV, 33kV), soil conditions, Installation type, Expected duration, And of course, The budget. Both International manufacturers as Regional manufacturers They can offer quality solutions, provided they have the necessary certifications and experience.
If you are developing a medium or high voltage electrical project, consult manufacturers such as Prysmian, Nexans, Southwire or regional suppliers such as Dosense Cable, who offer reliable products, technical support and regulatory compliance.
