Polycab Bus Cable – Profibus and FOUNDATION Fieldbus, Tinned Copper, XLPE, Screened, Armoured or Unarmoured

The Polycab Bus Cable is a screened network cable for Profibus and FOUNDATION Fieldbus systems, with tinned copper XLPE insulated pairs or cores, foil and drain-wire screens, and PVC, CPE or LSZH sheaths, unarmoured or armoured. Polycab's catalogue lists it as conforming to FF-844. It is supplied at a price on request: cable prices depend on the construction, the quantity and the raw-material prices on the day.

Polycab India Limited is India's largest manufacturer of wires and cables, with 27 manufacturing facilities, a network of 4,300+ dealers and distributors, 2,00,000+ retailers and an export presence in 84 countries (polycab.com, October 2026). Its cable range runs from house wires and 1.1 kV power and control cables to MV and EHV power cables, with instrumentation, solar, railway, marine, mining, fire-survival and other special cables. Jai Enterprises supplies Polycab cables from Bhilai and Raipur all over Chhattisgarh - Bhilai, Raipur, Durg, Korba, Bilaspur, Raigarh, Jagdalpur, Kanker, Ambikapur and every other district - and across India.

Is this the right one for you?

Check these four things before you order:

• You know the network: Profibus DP, Profibus PA or FOUNDATION Fieldbus H1.
• The cable impedance will match the network - typically 150 ohm for Profibus DP, 100 ohm for Profibus PA and Fieldbus H1.
• You know whether the segment runs in the field (armoured) or in panels.
• Connectors, terminators and the segment length will follow the network rules.

Construction and standards

• Conductor: annealed tinned copper
• Insulation: XLPE
• Elements: cores or pairs
• Screen: aluminium-Mylar or copper-Mylar tape with drain wire, individual and / or overall
• Inner sheath: as required
• Armour: unarmoured or armoured
• Outer sheath: PVC, CPE or LSZH
• FF-844: the FOUNDATION Fieldbus H1 cable test specification
• Note - Profibus: FF-844 tests FOUNDATION Fieldbus H1 cable. Profibus PA uses the same 31.25 kbit/s physical layer (IEC 61158-2) and a 100 ohm cable, so one cable type usually serves both; Profibus DP (RS-485) needs a 150 ohm cable - tell us the network
• Note - Screen: the catalogue picture shows a braid over the foil, and armour under the outer sheath; we confirm the screen construction on the datasheet

Why choose the Polycab Bus Cable

• Tinned copper conductors for corrosion resistance
• XLPE insulation
• Foil and drain-wire screens, individual and / or overall
• Armoured version for field runs in plants
• PVC, CPE or LSZH sheath

How to choose and specify it

Network type. Bus cables must match the network's characteristic impedance, or signals reflect and the segment becomes unreliable, and they must stay within the network's capacitance and attenuation limits. Tell us whether you need Profibus DP, Profibus PA or FOUNDATION Fieldbus H1, and we confirm the matching Polycab type.

Field or panel. Use the armoured version for cable trays and buried runs in the plant, and unarmoured cable inside panels and control rooms; choose LSZH where smoke matters.

Installation. Keep bus cables apart from power and VFD cables, earth the screen as the network guidelines say, and fit the terminators at both ends of each segment. In hazardous areas, use Ex-certified glands suited to the cable - armoured or unarmoured.

Where it is used

• Profibus DP networks between PLCs, drives and remote I/O

Frequently asked questions

What is the price of the Polycab Bus Cable?

The Polycab Bus Cable is supplied at a price on request, because cable prices depend on the construction, the quantity and the raw-material prices on the day. Call +91 9340081159 for a quotation.

Profibus or Fieldbus - is it the same cable?

Profibus PA and FOUNDATION Fieldbus H1 share the same 31.25 kbit/s physical layer and a 100 ohm cable, so one cable type usually serves both. Profibus DP needs a different, 150 ohm cable. Tell us the network and we confirm the matching type.

What is FF-844?

The FOUNDATION Fieldbus H1 cable test specification, which covers impedance, capacitive unbalance and attenuation for H1 cables.

Is an armoured version available?

Yes - the catalogue lists unarmoured and armoured bus cables, with PVC, CPE or LSZH sheaths.

Where can I buy the Polycab Bus Cable in Chhattisgarh?

From Jai Enterprises, Bhilai and Raipur, which supplies Polycab cables to every district of Chhattisgarh and across India. Call +91 9340081159 for the price, stock and lead time.
