IEC 60502-1 CVV-SWA Steel Wire Armoured Control Cable 600V
IEC 60502-1 referenced CVV-SWA Control Cable is a PVC-insulated, PVC-sheathed multicore copper control cable with galvanized steel-wire armour for fixed installations requiring added mechanical protection. It is intended for duct, cable-tray and direct-buried routes, including installations where the cable may be exposed to water along the route.
PRODUCT OVERVIEW
CVV-SWA combines stranded annealed copper conductors, PVC insulation, optional non-hygroscopic filler and polyester binding tape, a black PVC inner sheath, galvanized steel-wire armour, separator tape and a black PVC outer sheath. The armour is the defining feature of this construction: it protects the multicore control cable against external mechanical stress in buried, ducted and industrial installation routes.
The listed range covers 0.5 mm² to 6 mm² conductors and 2 to 30 cores. The source data states a maximum conductor temperature of 70°C, a circuit voltage not exceeding 600V and a 3500V test voltage. A special flame-retardant outer sheath can be supplied where required.
KEY FEATURES

- 2-30 cores in the listed technical range.
- Suitable for duct, cable tray and direct burial as stated in the source data.
- Source data states the cable may be subject to water immersion along the route.
- Maximum conductor temperature: 70°C.
- Circuit voltage: not exceeding 600V.
- Test voltage: 3500V.

STANDARD REFERENCE & COMPLIANCE
Item | Details |
Referenced Standard | IEC 60502-1 |
Current Edition | IEC 60502-1:2021 |
Product Rating | Steel-wire-armoured control cable for circuits up to 600V |
Compliance Note | IEC 60502-1 is referenced in the product specification. For projects requiring edition-specific compliance, confirm the required voltage designation and test documentation before approval. |
IEC 60502-1 is used here as the reference standard stated for the CVV-SWA product family. Where a project calls for a specific IEC edition, voltage designation or approval package, those requirements should be stated during technical review or quotation.
WHY CVV-SWA USES STEEL-WIRE ARMOUR
CVV-SWA is selected when a control cable needs physical protection in addition to its electrical insulation and sheath system. The galvanized steel wires form a robust armour layer around the inner-sheathed core assembly, helping protect the cable against mechanical stress during direct burial, duct installation and industrial routing.
Steel-wire armour should not be treated as the same function as an electrostatic screen. Where interference control is a project requirement, the need for a dedicated screened control-cable construction should be reviewed separately.
PRODUCT APPLICATIONS
- Industrial and utility control circuits requiring mechanical protection.
- Direct-buried control-cable routes.
- Underground duct installations.
- Cable-tray control wiring.
- Outdoor or plant installations where a steel-wire-armoured multicore control cable is specified.
- Routes where water exposure is anticipated and the overall installation system is designed accordingly.
INSTALLATION ENVIRONMENT
Duct Installation | Suitable as stated in the source data |
Cable Tray | Suitable as stated in the source data |
Direct Burial | Suitable as stated in the source data |
Water Exposure | Source data states the cable may be subject to immersion in water along the route |
For projects involving continuous or repeated water exposure, sealing, cable-entry, jointing and termination requirements should be confirmed as part of the complete installation design rather than inferred from the cable description alone.

Request the Complete Data Sheet
From Production to Delivery
From raw material preparation to final shipmen, every stage is caretuly controled to ensure consistent conductor quality, reliable pertormance,and sae delivery. Our roduction,
inspection, packaging, and logistics processes are managed in accordance with applicable standards and project requirements.
Production
Stranded annealed copper conductors are PVC insulated, cabled into the required multicore assembly, optionally filled and bound, covered with a black PVC inner sheath, armoured with galvanized steel wires, wrapped with separator tape and finished with the black PVC outer sheath.
Inspection
Inspection focuses on conductor size and resistance, PVC insulation and sheath condition, armour-wire diameter and continuity of the armour layer, overall dimensions, insulation resistance and test-voltage requirements.
Packaging
Finished cables are wound on suitable drums according to cable diameter, weight and ordered length. Drum identification can include cable type, conductor size, core count, length and project reference.
Shipping
Before shipment, drums and technical documents are checked against the order. Inspection records, product identification and requested test documents can be prepared for project approval.
Frequently Asked Questions
When should I choose CVV-SWA instead of standard CVV control cable?
Choose CVV-SWA when the route requires additional mechanical protection, especially for direct burial, duct installations or industrial locations where the cable may be exposed to external stress. The galvanized steel-wire armour adds physical protection that an unarmoured CVV cable does not provide. If the installation is fully protected and armour is unnecessary, standard CVV may be simpler and more economical.
Is CVV-SWA the same as a screened control cable?
No. The steel-wire armour is primarily a mechanical-protection layer, not a dedicated electrostatic screen. If the control circuit is sensitive to interference, the project should separately confirm whether a copper-tape or copper-braid screened cable is required.
Can this cable be directly buried?
Yes. Direct burial is explicitly listed as an intended application. The complete installation still needs suitable trench design, cable depth, mechanical protection where required, joints, glands and terminations consistent with the project specification and local installation rules.
How do I choose conductor size and core count for a control circuit?
Start with the number of control functions and spare-core requirement, then select conductor cross section according to circuit length, resistance and load. After the electrical selection, check overall diameter, cable weight, tray or duct capacity and termination space because the SWA construction can become relatively heavy at high core counts.
Can a flame-retardant version be supplied?
Yes. The product information states that a special flame-retardant outer sheath can be supplied. If the project specifies a particular flame test or fire-performance level, include that standard in the RFQ so the offered sheath construction and supporting documents can be confirmed.
What products do you supply for the power cable industry?
We provide a wide range of cable materials and electrical products, including aluminum conductors, aluminum rods, aluminum wires, overhead conductors, medium and low voltage power cables, cable insulation materials, filling materials, shielding materials, and cable manufacturing consumables.We provide customized solutions according to different cable manufacturing requirements.
