Meaning of CU/MGT/XLPE/LS/SFA/PVC-FR
The designation CU/MGT/XLPE/LS/SFA/PVC-FR 0.6/1 (1.2) kV clearly describes the cable structure from the conductor outward:
- CU – Copper Conductor
High-purity annealed copper conductor manufactured in accordance with IEC standards. - MGT – Mica Glass Tape
Fire-resistant tape applied over the conductor or insulation to maintain electrical integrity during fire. - XLPE – Cross-Linked Polyethylene Insulation
High-performance insulation material with excellent dielectric and thermal properties. - LS – Lead Sheath
A continuous metallic sheath providing moisture, 化学薬品, and corrosion protection. - SFA – Steel Flat Armour
Mechanical armour offering high resistance to impact, compression, and external forces. - PVC-FR – Flame Retardant PVC Outer Sheath
Final protective layer with enhanced flame-retardant performance.
This multilayer structure makes the cable particularly suitable for underground installations, tunnels, power plants, oil & gas facilities, refineries, 変電所, and emergency power circuits.
General Cable Construction
典型的な CU/MGT/XLPE/LS/SFA/PVC-FR 0.6/1 (1.2) kV FRケーブル consists of the following layers:
- Copper conductor (IEC 60228)
- Mica glass tape fire barrier
- XLPE絶縁体
- Laid-up cores with fillers (for multi-core cables)
- 鉛のシース (LS)
- PVC separator / bedding
- Steel flat armour (SFA)
- Flame retardant PVC outer sheath (PVC-FR)
Each layer serves a specific electrical, 熱, 機械的, or protective function.
Copper Conductor (CU)
The conductor is made of annealed electrolytic copper with high conductivity and excellent mechanical strength. Conductors are manufactured in accordance with IEC 60228, typically as:
- Class 1 – Solid conductor (mainly for small cross-sections)
- Class 2 – Stranded conductor (most common for power cables)
Copper conductors ensure:
- Low conductor resistance
- High current-carrying capacity
- Excellent thermal stability
- 長寿命
Mica Glass Tape (MGT) – Fire Resistance Layer
の mica glass tape layer is the key component that gives the cable its 耐火性の (FR) capability.
Main characteristics:
- Maintains insulation integrity under direct flame
- Withstands temperatures up to 750–950°C
- Prevents short circuits during fire exposure
- Enables circuit operation for emergency systems
This layer is essential for compliance with fire survival requirements in critical installations.
XLPE Insulation
XLPE絶縁体 is applied over the conductor or MGT layer.
Key advantages:
- Rated operating temperature: 90℃
- Short-circuit temperature: 250℃
- High dielectric strength
- Excellent resistance to moisture, 化学薬品, and aging
XLPE insulation ensures reliable power transmission even in harsh environments.
鉛のシース (LS)
の 鉛のシース (LS) is a continuous extruded metallic layer applied over the laid-up insulated cores.
Functions of Lead Sheath
- Excellent moisture barrier
- High resistance to oils, 化学薬品, and corrosive substances
- Protection against water ingress
- Enhanced electromagnetic shielding
Because of these properties, LS cables are widely used in underground, industrial, and chemically aggressive environments.
Steel Flat Armour (SFA)
の Steel Flat Armour (SFA) provides strong mechanical protection.
利点:
- High resistance to impact and crushing
- Suitable for direct burial
- Improved tensile strength
- Protection against rodent damage
SFA makes the cable suitable for heavy-duty installations where mechanical stress is expected.
PVC-FR Outer Sheath
The final layer is a Flame Retardant PVC (PVC-FR) アウターシース.
Functions:
- Flame retardancy
- UV resistance
- Protection against abrasion and weather
- Easy identification and installation
