YWY, AYFY, AYY, AYCY, A2XCY Cables Meanings

📘 Cable Nomenclature Explained (PVC & XLPE Cables)

Cable designations like YWY, AYFY, A2XCY might look confusing at first glance. But once you understand the logic behind each letter, reading technical specs becomes straightforward.

---

1. Basic Conductor Material

·         A → Aluminium conductor

·         (If “A” is absent, it means Copper conductor)

---

2. Insulation Material

·         Y → TROPODUR = PVC insulation

·         2X → TROPOTHEN-X = XLPE insulation

---

3. Armouring Types

·         W → Round Steel Wire Armouring

·         WW → Double Round Steel Wire Armouring

·         F → Flat (formed) Steel Strip Armouring

·         FF → Double Flat Steel Strip Armouring

·         Wa → Aluminium Wire/Strip Armouring

---

4. Screening

·         C → Copper metallic screen (overall)

·         CE → Copper screen on each core

·         Gb → Steel tape helix binder

---

5. Sheath

·         Y (at end) → TROPODUR = PVC outer sheath

---

6. Common Examples

Type	Full Form	Description
AYY	Aluminium, PVC insulated, PVC sheathed	Unarmoured heavy-duty cable
AYWY	Aluminium, PVC insulated, Steel wire armoured, PVC sheathed	Most common for power distribution
AYFY	Aluminium, PVC insulated, Flat strip armoured, PVC sheathed	For underground power networks
AYCY	Aluminium, PVC insulated, Copper screened, PVC sheathed	Used where EMC shielding is required
A2XCY	Aluminium, XLPE insulated, Copper screened, PVC sheathed	High-performance screened cable
AYCEFY	Aluminium, PVC insulated, Individually screened cores, Flat strip armoured, PVC sheathed	Special EMC + mechanical protection
A2XCEFY	Aluminium, XLPE insulated, Individually screened cores, Flat strip armoured, PVC sheathed	High-voltage EMC cable with XLPE

👉 If “A” is dropped → it’s the same type but with Copper conductor.
For example:

·         YY → Copper, PVC insulated & sheathed

·         YWY → Copper, PVC insulated, wire armoured, PVC sheathed

7. Special Mining Cables

·         YWWGby → Copper, PVC insulated, double wire armoured, PVC sheathed, Mining grade

·         YFFGby → Copper, PVC insulated, double flat strip armoured, PVC sheathed, Mining grade

---

🔑 Quick Decode Formula

[A or none] + [Insulation Code] + [Screen Code] + [Armour Code] + [Sheath Code]

Example:
AYFY = Aluminium + PVC insulation + Flat strip armour + PVC sheath
