1. Engineering position: a screened and aluminium-wire-armoured single-core MV cable
CU/XLPE/CTS/PVC/AWA/PVC 12.7/22 kV is a single-core, XLPE-insulated, copper-conductor medium-voltage cable with a copper tape metallic screen, PVC separation sheath, single-layer aluminium wire armour and PVC outer sheath. The source application is fixed energy-network service in residential or industrial areas, underground routes and ducts, including networks with sudden load changes and expected mechanical stresses.
Electric-field platform
The conductor screen, XLPE insulation and insulation screen form the radial dielectric system. The copper tape is the metallic electric-field boundary and an earth-fault path that requires continuity and bonding design.

AWA mechanical envelope
The single aluminium-wire armour layer is mechanically distinct from the copper tape screen. Armour continuity, bonding, corrosion environment, cleats and entry protection must be designed for the installation.

Data boundary: every supplied matrix value, dash field, construction layer, generated date, page label and source disclaimer is reproduced. Missing fields and route-specific assumptions are not filled from another cable family. The final Feichun release must govern the exact construction, tests, accessories and project ratings.
2. Designation and construction logic
| Designation / field | Engineering reading | Design consequence | Evidence status |
|---|---|---|---|
| CU | Copper phase conductor. | Use the exact cross-section row for DCR, ampacity, voltage drop and short-circuit screening. | Supplied construction |
| XLPE | Cross-linked polyethylene insulation around the screened conductor. | Coordinate insulation, semiconducting screens, terminations, joints and test levels with the 12.7/22 kV system. | Supplied construction |
| CTS | Copper tape metallic screen. | Control screen continuity, bonding, touch voltage, induced effects and earth-fault I²t. | Supplied construction / official product records |
| PVC / AWA / PVC | PVC separation sheath, single-layer aluminium wire armour and PVC outer sheath. | Keep electrical screen duties separate from mechanical armour duties; verify PVC fire and environmental evidence for the project. | Supplied construction / official product records |
| 12.7/22 (24) kV | Rated voltage Uo/U (Um). | Confirm system earthing, switching, withstand, accessory class and protection coordination. | Supplied characteristic field |
Layer sequence
Copper conductor → semiconducting conductor screen → XLPE insulation → semiconducting insulation screen → crape-paper semiconducting tape → copper tape metallic screen → PVC separation sheath → single-layer aluminium wire armour → PVC outer sheath.
Copper conductor → semiconducting conductor screen → XLPE insulation → semiconducting insulation screen → crape-paper semiconducting tape → copper tape metallic screen → PVC separation sheath → single-layer aluminium wire armour → PVC outer sheath.
Screen and armour are not interchangeable
The copper tape is an electrical screen. The AWA layer is a mechanical armour. Their continuity, bonding, thermal duty and accessory interfaces must be verified independently.

3. Standards and evidence review
| Reference | Role | Engineering interpretation | Boundary |
|---|---|---|---|
| BS 6622 | Product standard listed by the supplied source. | BSI describes the standard as covering armoured thermosetting-insulated cables for fixed network or industrial installations across the relevant voltage range, including copper or aluminium conductors, metallic screens and aluminium or galvanised-steel armour options. | Confirm adopted edition and exact Feichun conformity file. |
| IEC 60332-1-2 | Flame-retardant reference listed by the source. | The official IEC procedure concerns vertical flame propagation for a single insulated wire or cable using a 1 kW pre-mixed flame. | Test-method reference; not a grouped-cable fire declaration or CPR class by itself. |
| IEC 60502-2 | Related international MV cable reference. | It is included for engineering cross-reference to extruded-insulation MV fixed-installation cable practice. | Not listed as the product standard in the supplied record; verify project adoption separately. |
| PVC sheath system | Separation and outer sheath material. | Evaluate fire, smoke, corrosive gas, chemical, UV, water, impact, enclosure and penetration requirements for the actual route. | No CPR class, LSZH declaration or halogen-free claim is supplied. |
| Source hierarchy | User record versus official additions. | Supplied values are primary; official pages add independently labelled construction and product-list context; derived radii are arithmetic checks. | Feichun project dossier controls procurement release. |
Scope distinction: a product standard and a single-cable flame test do not automatically qualify a cable for mining, shipboard, reeling, festoon, drag-chain or other dynamic special service. Those applications need their own construction and test evidence.

12. Handling and termination
- Confirm the exact controlled product reference from 10536096 through 10536078, including cross-section, outer diameter, mass, DCR, screen and armour details.
- Apply the 15×D laying factor to the ordered diameter. The supplied matrix gives a derived screening range of 495.0 mm at 33.0 mm OD to 855.0 mm at 57.0 mm OD.
- Keep the drum aligned with the pay-off direction. Prevent reverse winding, uncontrolled twist, flange impact and local PVC sheath or AWA damage.
- Use rollers and supports that control bending, sidewall pressure and armour loading. Do not pull against a sharp duct entry or force the copper screen around a local obstruction.
- Prepare the conductor screen, XLPE insulation, semiconducting screen, copper tape, PVC separation sheath, AWA and PVC outer sheath using the approved termination or joint kit method.
- Record screen continuity, armour continuity and bonding, phase identification, conductor resistance, insulation and sheath tests, torque and accessory inspection before energisation.
- Complete MV withstand or partial-discharge tests where specified by the project, and retain product reference, batch, test results and as-built route records.
Installation release: the 15×D value is a laying-factor reference. It does not authorize repeated bending, torsion, reel operation or energy-chain installation.
