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

1. موصل النحاس (IEC compliant)
2. العزل XLPE
3. Laid-up insulated cores with fillers
4. PVC inner sheath
5. غمد الرصاص (إل إس)
6. فاصل بي في سي / الفراش
7. درع فولاذي مسطح (SFA)
8. PVC outer sheath

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

موصل النحاس (سو)

يتكون الموصل من high-purity annealed electrolytic copper, offering excellent conductivity and mechanical stability. All conductors comply with اللجنة الانتخابية المستقلة 60228, typically manufactured as:

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

تضمن الموصلات النحاسية:

• Low electrical resistance
• قدرة حمل عالية للتيار
• Stable performance under thermal stress
• Long operational life

عزل XLPE

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 90درجة مئوية
• Short-circuit temperature up to 250درجة مئوية
• قوة عازلة عالية
• مقاومة ممتازة للرطوبة, المواد الكيميائية, والشيخوخة

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

PVC Inner Sheath

After core assembly, أ 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

غلاف ارصاص (إل إس)

ال غلاف ارصاص (إل إس) 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, المواد الكيميائية, والمواد المسببة للتآكل
• Prevents water ingress in underground installations
• Enhances electromagnetic shielding

بسبب هذه الخصائص, lead-sheathed cables are widely used in underground power networks, industrial facilities, الأنفاق, 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.

درع مسطح من الفولاذ (SFA)

ال درع مسطح من الفولاذ (SFA) provides strong mechanical protection against external forces.

Advantages of SFA include:

• مقاومة عالية للصدمات والسحق
• Excellent tensile strength
• مناسبة للدفن المباشر
• الحماية من أضرار القوارض

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) كيلو فولت

The rated voltage 0.6/1 (1.2) كيلو فولت 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 الأساسية ل 5 النوى (0.5 ملم² إلى 300 مم²)

IEC Power Cable Conductor Configuration

IEC Conductor Configuration – 1 الأساسية ل 36 النوى (0.5 ملم² إلى 10 مم²)

IEC Multi-Core Cable Configuration

These configurations are commonly used for الكابلات السيطرة, auxiliary power circuits, and industrial distribution systems.
