Medium Voltage XLPE Cable for Data Center Infrastructure
Medium voltage XLPE cable is commonly used in large data center projects for main power distribution, transformer connection, switchgear connection and facility-level electrical infrastructure. Common voltage ratings may include 6/10kV, 8.7/15kV, 12/20kV, 18/30kV and 26/35kV depending on project requirements.
XLPE insulation provides reliable electrical insulation performance and thermal stability, making it suitable for continuous power distribution in demanding infrastructure systems. For medium voltage data center cable projects, buyers should confirm shielding, metallic screen, armor, sheath and required standards before requesting a quotation.
Low Voltage Power Cable for Server Rooms and Equipment Areas
Low voltage power cable is widely used in data centers for internal power distribution, server room electrical systems, UPS output circuits, distribution cabinets, cooling systems and facility power supply.
PVC insulated power cable may be suitable for some low voltage applications where project requirements allow. XLPE insulated low voltage cable may be considered when higher thermal performance or specific project requirements are needed.
For enclosed equipment rooms, buyers should also confirm fire safety requirements, sheath material and installation method before selecting low voltage cable.
Fire Safety Requirements in Data Centers
Fire safety is an important factor in data center power cable selection. Since data centers include enclosed equipment rooms, server rooms, cable trays and electrical distribution areas, cable materials may need to meet flame-retardant, fire-resistant or low smoke halogen-free requirements depending on project specifications.
LSZH sheath may be required in some data center or telecommunications projects where low smoke and halogen-free performance is important. Fire-resistant cable may be required for critical circuits or emergency systems depending on the electrical design.
Before requesting a quotation, buyers should confirm:
- Whether flame-retardant cable is required
- Whether fire-resistant cable is required
- Whether LSZH sheath is required
- Whether the cable is used in server rooms, equipment rooms or public infrastructure areas
- Required project standard and documentation
Copper or Aluminum Conductor for Data Center Cable?
Data center power cables can use copper or aluminum conductors depending on electrical design, current load, installation space and budget. Copper conductors provide high electrical conductivity, compact cable size and stable performance. They are often selected for demanding power systems, limited installation spaces and high reliability applications.
Aluminum conductors are lighter and may provide cost advantages for larger power distribution systems or longer cable routes. They may be suitable when the electrical design allows larger conductor sizes and when project cost control is important.
| Conductor Material | Main Advantages | Typical Data Center Use |
|---|---|---|
| Copper Conductor | High conductivity, compact size, stable performance | Server rooms, electrical rooms, UPS systems, demanding power systems |
| Aluminum Conductor | Lightweight and cost-effective for larger projects | Main distribution, longer cable routes, infrastructure systems |
The final selection should be based on current-carrying capacity, cable route length, voltage drop, available installation space, project budget and required standards.
Armored or Non-Armored Cable for Data Centers?
Data center cables may be installed in cable trays, ducts, conduits, electrical rooms, underground routes or utility areas. Armor requirement depends on the installation environment and mechanical protection needs.
Non-armored cable may be suitable for protected indoor installation, ducts, conduits and cable trays where mechanical damage risk is low. Armored cable may be required for underground routes, utility areas, cable trenches or mechanically demanding environments.
- Choose non-armored cable for protected indoor cable trays or ducts
- Choose armored cable for underground routes, utility trenches or high-risk mechanical environments
