XLPE絶縁
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℃
- 高い絶縁耐力
- 優れた耐湿性, 化学薬品, そして老化
XLPE insulation ensures safe and reliable power transmission even in harsh operating environments.
PVC Inner Sheath
After core assembly, ある 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
鉛のシース (LS)
の 鉛のシース (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, 化学薬品, および腐食性物質
- Prevents water ingress in underground installations
- Enhances electromagnetic shielding
こういった性質があるため、, lead-sheathed cables are widely used in underground power networks, industrial facilities, トンネル, 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.
スチールフラットアーマー (SFA)
の スチールフラットアーマー (SFA) provides strong mechanical protection against external forces.
Advantages of SFA include:
- 衝撃や潰れに対する高い耐性
- Excellent tensile strength
- 直葬に最適
- げっ歯類の被害からの保護
Steel flat armour makes the cable suitable for heavy-duty industrial and infrastructure installations.
PVCアウターシース
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
定格電圧: 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.
