Energy storage battery cable for containerised BESS

Fine-strand, low-smoke battery cable for cell, rack and PCS connections in containerised energy storage systems.

System voltage1500 V DC
ConductorClass 6 tinned copper
SheathLSZH
Temperature105 °C
Product overview

Construction and performance

Battery connection cable carries current in both directions and is terminated inside an enclosure where space is tight and a cell fire is the design case. The construction therefore combines a Class 6 tinned conductor for tight bending, XLPO insulation for thermal margin, and a low-smoke halogen-free sheath for the enclosure environment.

Construction

  • Tinned copper conductor, Class 6
  • Cross-linked XLPO insulation
  • LSZH sheath, low smoke and halogen free
  • Flexible for rack dressing
  • Optional screened construction for BMS

Applications

  • Cell-to-cell and cell-to-rack links
  • Rack to PCS and DC bus
  • BMS and auxiliary power feed
  • Container HVAC and fire system supply

Selection notes

What to confirm before ordering

How is the cable sized for a battery rack?
Size on continuous current with the enclosure ambient and the grouping factor, then check voltage drop over the run. Paralleled cables must be the same length and construction. We can review the rack schedule and confirm the section.
Is a screened version available?
Yes. A screened construction is available where BMS or communication pairs share the same route as the DC cables.
What terminations are used?
Cable is normally supplied as cut lengths; pre-assembled lugs and heat-shrink can be quoted where the rack layout is fixed.

Need a sample or datasheet?

Tell us the system voltage, conductor size, length and destination. We can prepare a construction drawing and sample for review.

Packing and delivery

From the reel to the site gate

Cable is packed so it can be pulled without a re-reel, and documented so the site team can match each drum to the test report.

Drum packing

Wooden or steel-wooden drums for constructions above 16 mm², with lagging and a PE wrap. Drum diameter is selected so the cable is not bent below its minimum bending radius.

Coil and box

Small sizes and short lengths are supplied as coils in cartons or on pallets, wrapped and labelled with the same drum numbers used in the packing list.

Length control

Continuous length is measured during rewinding, and the delivered length is stated on the drum plate and the packing list. Short-length tolerance is agreed in the order.

Reel marking

Each drum is marked with product description, size, voltage rating, standard, length, gross weight, drum number and the project or PO reference.

Container loading

Drum layout and quantity per 20′ or 40′ container are planned by diameter and weight; a loading plan is issued before shipment.

Export documentation

Commercial invoice, packing list, bill of lading and certificate of origin are issued for the shipment; FOB, CIF and DAP terms are quoted on request.

Shipping documents

What travels with the shipment

  • Packing list with drum number, size, length and gross weight
  • Routine test report for the delivered length
  • Declaration of conformity and certificate copies for the tender file
  • Loading plan and photos before the container is sealed
