Applications of 15kV Trilayer Insulated Aerial Cable in Colombia
The use of this cable has spread in multiple sectors.
Urban electrical distribution networks
Ideal for densely populated areas where bare wire poses risks.
Rural networks
Widely used by rural energy companies due to its durability and greater safety when in contact with trees.
Industrial facilities
For oil plants, cement plants, ports and critical infrastructures.
Electrical expansion projects
Widely used by distribution companies such as:
- Codensa (Bogota)
- EPM (Medellín)
- Celsius (Cauca Valley)
- On it / Athens (Atlantic Coast)
Remodeling of old lines
Replacing bare cables with insulated cables to reduce failures.
Advantages of installing 15kV Three-Layer Insulated Aerial Cable
Greater electrical safety
Insulation significantly reduces:
- downloads
- accidental contacts
- vegetation short circuits
Fewer service interruptions
Networks with tri-layer cable have fewer failures during electrical storms.
Resistance to tropical environments
Supports:
- heavy rain
- solar radiation
- humidity
- coastal air pollution
Less maintenance
Insulated cables require less tree pruning.
Longer useful life
A correct installation can exceed 25–30 years.
Reduction of energy losses
Thanks to lower incidence of failures and better dielectric efficiency.
Types of 15kV Trilayer Insulated Aerial Cable depending on the conductor
Cable tricapa 15kV AAC
Economic, light, ideal for urban areas.
Cable tricapa 15kV AAAC
Greater mechanical and corrosion resistance.

15kV Trilayer Insulated Aerial Cable Price Colombia — What does it depend on??
The price of the cable varies depending on multiple factors.
Driver material
- AAC（more economical）
- AAAC（average price）
- ACSR（more expensive because of steel）
Driver section (mm²)
The most used calibers in Colombia:
- 35 mm²
- 50 mm²
- 70 mm²
- 95 mm²
- 120 mm²
- 150 mm²
- 185 mm²
The larger section, higher price per meter.
Three-layer layer and insulation thickness
Three-layer XLPE has more advanced technology than single XLPE.
Price of aluminum in the international market
The value of the cable is directly related to the LME price.
Required quantity
Higher volumes allow for better FOB or CIF prices.
Logistics cost to Colombia
Includes:
- maritime cargo
- insurance
- customs clearance
- internal transport
General price estimate
Reference price in Colombia (variable depending on project):
USD 2.50 – 9.50 per meter, depending on the gauge and type of conductor.
(Use: This is a general range, The actual price depends on technical specification and volume.)
How to choose the right 15kV Trilayer Insulated Aerial Cable for your project in Colombia
1. Identify the type of network
- Urbana
- Rural
- Industrial
- Self-supporting
2. Calculate the required current
Depends on the total load of the project.
3. Analyze the distance of the openings
Affects whether you need AAAC or ACSR.
4. Verify standards required by the local operator
EPM, Codensa and Celsia usually require specific certifications.
5. Check the quality of the three-layer insulation
