General Cable Construction
A typical CU/MGT/XLPE/LS/SFA/PVC-FR 0.6/1 (1.2) кВ FR кабель consists of the following layers:
- Copper conductor (IEC 60228)
- Mica glass tape fire barrier
- XLPE insulation
- Laid-up cores with fillers (for multi-core cables)
- Lead sheath (LS)
- PVC separator / bedding
- Steel flat armour (SFA)
- Flame retardant PVC outer sheath (PVC-FR)
Each layer serves a specific electrical, дулааны, механик, 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:
- Анги 1 – Solid conductor (mainly for small cross-sections)
- Анги 2 – Stranded conductor (most common for power cables)
Copper conductors ensure:
- Low conductor resistance
- High current-carrying capacity
- Excellent thermal stability
- Long service life
Mica Glass Tape (MGT) – Fire Resistance Layer
The mica glass tape layer is the key component that gives the cable its галд тэсвэртэй (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 insulation is applied over the conductor or MGT layer.
Key advantages:
- Rated operating temperature: 90°C
- Short-circuit temperature: 250°C
- High dielectric strength
- Excellent resistance to moisture, химийн бодис, and aging
XLPE insulation ensures reliable power transmission even in harsh environments.
Хар тугалга бүрээс (LS)
The Хар тугалга бүрээс (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, химийн бодис, and corrosive substances
- Protection against water ingress
- Enhanced electromagnetic shielding
Because of these properties, LS cables are widely used in underground, аж үйлдвэрийн, and chemically aggressive environments.
Steel Flat Armour (SFA)
The Steel Flat Armour (SFA) provides strong mechanical protection.
Давуу тал:
- 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) outer sheath.
Functions:
- Flame retardancy
- UV resistance
- Protection against abrasion and weather
- Easy identification and installation
