With its multi-layer construction and armoured design, this cable is widely used in plantas industriais, power distribution networks, instalações subterrâneas, e projetos de infraestrutura.

A designação N2XKFGbY follows European and IEC-based cable naming conventions and represents a cable system that combines condutores de cobre, Isolamento XLPE, a lead sheath (LS), steel flat armour (SFA), and multiple PVC protective layers. The rated voltage of 0.6/1 (1.2) kV makes it suitable for low-voltage power transmission under demanding environmental and mechanical conditions.

Meaning of N2XKFGbY (CU/XLPE/PVC/LS/LS/SFWA/PVC)

The structure of the N2XKFGbY cable can be clearly understood by breaking down its material designation:

• UC – Copper conductor
• XLPE – Cross-linked polyethylene insulation
• PVC – Polyvinyl chloride inner sheath and bedding layers
• LS – Lead Sheath
• PVC – Separator / bedding sheath over the lead sheath
• SFA – Steel Flat Armour
• PVC – PVC outer sheath

Junto, this construction delivers a cable with excellent electrical performance, forte proteção mecânica, and superior resistance to moisture and aggressive environments.

Construção Geral de Cabos

Um típico N2XKFGbY (CU/XLPE/PVC/LS/LS/SFWA/PVC) 0.6/1 (1.2) cabo kV consists of the following layers from inside to outside:

1. Condutor de cobre (IEC compliant)
2. Isolamento XLPE
3. Laid-up insulated cores with fillers
4. PVC inner sheath
5. Bainha de chumbo (LS)
6. Separador de PVC / roupa de cama
7. Armadura plana de aço (SFA)
8. Bainha externa de PVC

Each layer is carefully engineered to serve a specific electrical or mechanical function.

Condutor de cobre (UC)

O condutor é feito de high-purity annealed electrolytic copper, offering excellent conductivity and mechanical stability. All conductors comply with CEI 60228, typically manufactured as:

• Aula 1 solid conductors (for smaller cross-sections)
• Aula 2 stranded conductors (for power applications)

Condutores de cobre garantem:

• Baixa resistência elétrica
• Alta capacidade de transporte de corrente
• Stable performance under thermal stress
• Long operational life

Isolamento XLPE

Each copper conductor is insulated with polietileno reticulado (XLPE), a material widely recognized for its superior electrical and thermal performance.

Key properties of XLPE insulation include:

• Continuous operating temperature up to 90°C
• Short-circuit temperature up to 250°C
• Alta rigidez dielétrica
• Excelente resistência à umidade, produtos químicos, e envelhecimento

XLPE insulation ensures safe and reliable power transmission even in harsh operating environments.

PVC Inner Sheath

After core assembly, a PVC inner sheath is applied to bind the insulated conductors together and provide a smooth surface for the application of the lead sheath.

Functions of the PVC inner sheath:

• Maintains cable geometry
• Protects insulated cores
• Improves mechanical stability
• Enhances overall durability

Bainha de chumbo (LS)

O Bainha de chumbo (LS) is one of the most critical features of the N2XKFGbY cable.

Functions of the Lead Sheath

• Acts as a complete moisture barrier
• Provides excellent resistance to oils, produtos químicos, e substâncias corrosivas
• Prevents water ingress in underground installations
• Enhances electromagnetic shielding

Por causa dessas propriedades, lead-sheathed cables are widely used in underground power networks, industrial facilities, túneis, and areas with high humidity or chemical exposure.

PVC Separator / Bedding Sheath

A PVC separator sheath is applied over the lead sheath to:

• Protect the lead sheath from mechanical damage
• Provide a smooth bedding for the armour layer
• Improve overall cable flexibility

This layer also contributes to the long-term stability of the cable under mechanical stress.

Armadura Plana de Aço (SFA)

O Armadura Plana de Aço (SFA) provides strong mechanical protection against external forces.

Advantages of SFA include:

• Alta resistência ao impacto e esmagamento
• Excellent tensile strength
• Adequado para enterro direto
• Proteção contra danos causados ​​por roedores

Steel flat armour makes the cable suitable for heavy-duty industrial and infrastructure installations.

PVC Outer Sheath

The final layer is a durable Bainha externa de PVC, designed to protect the cable from environmental influences.

Key features:

• Resistance to abrasion and mechanical wear
• Protection against UV radiation and weather
• Additional moisture resistance
• Easy identification and handling

Tensão nominal: 0.6/1 (1.2) kV

The rated voltage 0.6/1 (1.2) kV indicates:

• 0.6 kV between conductor and earth
• 1.0 kV between conductors
• 1.2 kV maximum system voltage

This rating makes the cable suitable for standard low-voltage power distribution systems.

IEC Conductor Configuration – 1 Núcleo para 5 Núcleos (0.5 mm² para 300 mm²)

IEC Power Cable Conductor Configuration

IEC Conductor Configuration – 1 Núcleo para 36 Núcleos (0.5 mm² para 10 mm²)

IEC Multi-Core Cable Configuration

These configurations are commonly used for cabos de controle, auxiliary power circuits, and industrial distribution systems.
