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

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

• CU – 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

Together, this construction delivers a cable with excellent electrical performance, strong mechanical protection, and superior resistance to moisture and aggressive environments.

General Cable Construction

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

1. Copper conductor (IEC compliant)
2. XLPE 단열재
3. Laid-up insulated cores with fillers
4. PVC inner sheath
5. 납 외장 (LS)
6. PVC separator / bedding
7. Steel flat armour (SFA)
8. PVC outer sheath

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

Copper Conductor (CU)

The conductor is made of high-purity annealed electrolytic copper, offering excellent conductivity and mechanical stability. All conductors comply with IEC 60228, typically manufactured as:

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

Copper conductors ensure:

• Low electrical resistance
• High current-carrying capacity
• Stable performance under thermal stress
• Long operational life

XLPE Insulation

Each copper conductor is insulated with cross-linked polyethylene (XLPE), a material widely recognized for its superior electrical and thermal performance.

Key properties of XLPE insulation include:

• Continuous operating temperature up to 90℃
• Short-circuit temperature up to 250℃
• High dielectric strength
• Excellent resistance to moisture, 약, and aging

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

PVC Inner Sheath

After core assembly, 에이 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

납 외장 (LS)

그만큼 납 외장 (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, 약, and corrosive substances
• Prevents water ingress in underground installations
• Enhances electromagnetic shielding

Because of these properties, lead-sheathed cables are widely used in underground power networks, industrial facilities, tunnels, 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.

Steel Flat Armour (SFA)

그만큼 Steel Flat Armour (SFA) provides strong mechanical protection against external forces.

Advantages of SFA include:

• High resistance to impact and crushing
• Excellent tensile strength
• Suitable for direct burial
• Protection against rodent damage

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

PVC Outer Sheath

The final layer is a durable PVC outer sheath, 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

Rated Voltage: 0.6/1 (1.2) 케이 V

The rated voltage 0.6/1 (1.2) 케이 V 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 Core to 5 Cores (0.5 mm² ~ 300 mm²)

IEC Power Cable Conductor Configuration

IEC Conductor Configuration – 1 Core to 36 Cores (0.5 mm² ~ 10 mm²)

IEC Multi-Core Cable Configuration

These configurations are commonly used for 제어 케이블, auxiliary power circuits, and industrial distribution systems.
