In modern power distribution and transmission,
XLPE (Cross-Linked Polyethylene) insulated cables are the industry standard for underground systems.
Here’s a quick guide to commonly used XLPE cables and their typical applications:
1). 1.5 mm² - 6 mm² (LV)
2). 10 mm² - 50 mm² (LV/MV)
3). 70 mm² - 120 mm² (MV)
4). 150 mm² - 300 mm² (MV)
5). 400 mm² - 630 mm² (HV)
6). 800 mm² - 1600 mm² (HV/EHV)
7). 2000 mm² - 2500 mm² (EHV)
1). 1.5 mm² - 6 mm² (LV)
Ideal for domestic wiring, lighting circuits & small commercial installations. Flexible and easy to install.
2). 10 mm² - 50 mm² (LV/MV)
Used in small-scale underground networks such as residential developments and street lighting.
3). 70 mm² - 120 mm² (MV)
Common in 11 kV distribution systems.
Balances current capacity and installation cost.
4). 150 mm² - 300 mm² (MV)
Suited for industrial feeders and medium-load substations in the 11–33 kV range.
5). 400 mm² - 630 mm² (HV)
Used for 33–132 kV underground transmission. Handles higher loads with excellent thermal stability.
6). 800 mm² - 1600 mm² (HV/EHV)
Found in major utility infrastructure and grid interconnections. High capacity with superior performance.
7). 2000 mm² - 2500 mm² (EHV)
Applied in 220–400 kV transmission corridors. Supports long-distance, high-load transfer with minimal loss.
Why XLPE?
High thermal resistance
Low dielectric loss
Moisture-resistant and chemically stable
Long service life with minimal maintenance
Selecting the right XLPE cable ensures safety, reliability, and efficiency in underground power systems.
