PVC Cable Supplier Guide: Choosing PVC Insulated and Sheathed Conductor Control Cables 0.6/1kV

Step 1: Define your buyer requirements first

Get these answers from your project before you compare control cable options:

1. Rated voltage of the circuit. Is it 0.6/1kV, or 450/750V or less?
2. Function. Is the cable for control and signalling between equipment, or for power supply and distribution?
3. Number of cores and conductor size. These come from your control schematic, including any spare cores.
4. Installation route. Indoors, outdoors, underground, in ducts or conduit, or on trays and ladders.
5. Mechanical protection. Do you need armour for burial, crush or pulling loads?
6. Continuous operating temperature at the conductor.
7. Fire performance. Does your project or local code call for flame-retardant PVC?
8. Standard references that your specification or local authority requires.

Buyers in different target markets often work to different national or project standards. Check that the standard named on the product data matches the one in your specification. Don't assume they're equivalent.

Step 2: Check the 0.6/1kV control cable specification

These are the published details for the PVC Insulated and Sheathed Conductor Control Cables 0.6/1kV:

The product description says this cable suits a broad range of commercial, industrial and utility applications.

Selection checks for this cable

• Voltage: Choose this cable when the circuit needs a 0.6/1kV rating.
• Size range: Published conductor sizes are 1.5, 2.5 and 4 mm² only. If your schematic calls for 0.5, 0.75, 1, 6 or 10 mm², this cable as published doesn't cover it. Look at the 450/750V control cable below, or ask the supplier to confirm.
• Core count: The standard counts are 7, 12, 19, 24, 30 and 37. Other counts are listed as available on request, so confirm any non-standard count in writing.
• Temperature: Say which insulation you need: type 5 rated 85°C or type 1 rated 70°C.
• Armour: Choose galvanized steel tape or round steel wire armour, or an unarmoured build, to suit the route. For underground or mechanically exposed runs, put armour on the order.
• Fire performance: The standard sheath is PVC type ST2. If you need flame-retardant PVC, request it explicitly. Ask which flame test applies, because the published data for this cable doesn't name one.
• Core numbering: Numbered black cores can make termination simpler on multi-core runs. Check that this identification method is acceptable under your project's wiring rules.

Step 3: Compare with the 450/750V PVC Insulated Control Cable

Some control circuits only need a rating of 450/750V or less. For those, the PVC Insulated Control Cable may fit better. Its published data describes it as suitable for distribution equipment, instrumentation connection and control systems at rated voltage 450/750V or less.

Key published points:

• Operating temperature: The maximum permissible continuous conductor temperature is 70°C.
• Laying temperature: The ambient temperature during laying should not be below 0°C. Otherwise, preheat the cable.
• Bending radius: 16D for armoured cable and 8D for unarmoured cable, where D is the actual outer diameter.
• Standard: GB9330-88 or other standards required by customers. Flame-retardant versions are made on request, with flame-retardant performance according to IEC 60332-3, categories B and C.
• Constructions: Plain Cu/PVC/PVC, copper tape screened, copper wire braiding screened, steel tape armoured, steel wire armoured, and flexible versions.
• Supply range: Nominal cross sections from 0.5 to 10 mm². Core counts depend on construction and size, for example 2 to 61 cores for Cu/PVC/PVC at the smaller sizes.
• Packing: Steel/wooden reel, wooden reel or steel reel.

The published application ranges by construction:

• Unscreened PVC sheathed: fixed laying indoors, in cable trench or conduit.
• Copper tape screened: the same routes where a screen is required.
• Steel tape armoured: fixed laying indoors, in cable trench, in conduit or directly buried, where the cable has to bear larger mechanical force.
• Steel wire armoured: fixed laying indoors, in cable trench, conduit or well, where the cable has to bear larger pulling force.
• Flexible versions: fixed laying indoors where flexibility is needed in moving. Screened flexible versions are available where a screen is also needed.

Where it does not apply: Don't specify this cable for a circuit that needs a 0.6/1kV rating, or for a continuous conductor temperature above 70°C.

Step 4: Don't substitute a power cable for a control cable

The 0.6/1kV PVC Insulated Power Cable has the same voltage class but is published for a different job. It is for power supply and distribution circuits in manufacturing and processing plants, commercial buildings or residences at 0.6/1kV or less. Its published data covers copper or aluminium conductors from 1.5 to 630 mm² (single core). It also gives a 70°C maximum continuous conductor temperature and a 160°C short-circuit limit for no more than 5 seconds, and cites IEC 60502 and flame-retardant references to IEC 60332-3 and GB18380.

If your requirement is multi-core control wiring with numbered cores, the power cable isn't the right product. If your requirement is a feeder or distribution circuit, the control cable isn't either.

Quick selection summary

What to ask your PVC cable supplier

When you send an enquiry to a PVC cable supplier, include:

• Voltage rating, core count and conductor size for each line item
• Insulation type and temperature rating
• Armoured or unarmoured construction, and the armour type
• Whether flame-retardant PVC is required, and to which test standard
• The standards your project requires, plus a request for supporting documents
• Packing preference (reel type)
• Quantity and required delivery date, so the supplier can confirm price and lead time in writing

The published product data doesn't state prices, delivery times or certificates. Those must come from the supplier's written quotation and documents.
