Energy storage monitoring cable for BMS and EMS links

Screened pair and triad cable for BMS, EMS and Modbus communication inside storage containers and switch rooms.

Rated voltage300/500 V
ScreenFoil + braid
Pairs1–24 pairs
StandardIEC 60228
Product overview

Construction and performance

Inside a battery container, communication cable runs next to the DC bus. Without a screen, switching noise from the PCS ends up on the BMS link. ZMS monitoring cable uses twisted pairs with an aluminium foil screen and a tinned copper drain, so the signal stays readable along the rack.

Construction

  • Tinned copper, Class 5
  • Twisted pairs or triads
  • Al-PET foil screen with drain wire
  • Optional copper braid for high-noise routes
  • LSZH or PVC sheath

Applications

  • BMS rack-to-BCU communication
  • EMS and plant controller links
  • Modbus RTU / RS-485 networks
  • Temperature and voltage sensing

Selection notes

What to confirm before ordering

Which screen should be earthed?
The screen is normally earthed at one end to avoid circulating currents, with the drain wire connected at the controller. Both ends are used where high-frequency noise dominates.
Is 120 Ω impedance available?
Yes. RS-485 constructions are available with 120 Ω nominal impedance for long Modbus runs.
Can the cable be supplied with connectors?
Pre-terminated assemblies can be quoted where the rack layout and connector type are known.

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
