The CU/MGT/XLPE/LS/SFA/PVC-FR 0.6/1 (1.2) кВ FR кабелі is a high-performance, отқа төзімді, қуатты таратудың маңызды жүйелеріне арналған брондалған төмен вольтты қуат кабелі. This cable combines electrical reliability, өрттен аман қалу мүмкіндігі, mechanical protection, and environmental resistance, making it suitable for demanding industrial and infrastructure applications.

With a construction consisting of Copper Conductor (CU), Mica Glass Tape (MGT), XLPE оқшаулау, Lead Sheath (LS), Steel Flat Armour (SFA), and a Flame Retardant PVC outer sheath, this cable is engineered to maintain circuit integrity even under severe fire and mechanical stress conditions.

The rated voltage of 0.6/1 (1.2) кВ makes it ideal for low-voltage power transmission where safety, төзімділік, and long service life are mandatory.

Meaning of CU/MGT/XLPE/LS/SFA/PVC-FR

The designation CU/MGT/XLPE/LS/SFA/PVC-FR 0.6/1 (1.2) кВ 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, химиялық, 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, май & gas facilities, refineries, substations, and emergency power circuits.

General Cable Construction

Типтік CU/MGT/XLPE/LS/SFA/PVC-FR 0.6/1 (1.2) кВ FR кабелі consists of the following layers:

1. Copper conductor (IEC 60228)
2. Mica glass tape fire barrier
3. XLPE оқшаулау
4. Laid-up cores with fillers (for multi-core cables)
5. Қорғасын қабық (LS)
6. PVC separator / bedding
7. Steel flat armour (SFA)
8. Flame retardant PVC outer sheath (Pvc-Fri)

Each layer serves a specific electrical, термиялық, механикалық, 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:

• Сынып 1 – Solid conductor (mainly for small cross-sections)
• Сынып 2 – Stranded conductor (most common for power cables)

Copper conductors ensure:

• Low conductor resistance
• High current-carrying capacity
• Excellent thermal stability
• Ұзақ қызмет ету мерзімі

Mica Glass Tape (MGT) – Fire Resistance Layer

The mica glass tape layer is the key component that gives the cable its отқа төзімді (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 оқшаулау 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, химиялық заттар, and aging

XLPE insulation ensures reliable power transmission even in harsh environments.

Lead Sheath (LS)

The Lead Sheath (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, химиялық заттар, and corrosive substances
• Protection against water ingress
• Enhanced electromagnetic shielding

Because of these properties, LS cables are widely used in жер асты, industrial, and chemically aggressive environments.

Steel Flat Armour (SFA)

The Steel Flat Armour (SFA) provides strong mechanical protection.

Артықшылықтары:

• 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-Fri) сыртқы қабық.

Functions:

• Flame retardancy
• UV resistance
• Protection against abrasion and weather
• Easy identification and installation
