Cable Construction

The cables robust construction consists of several concentric layers, each serving a vital purpose.

Conductor: The core of the cable is a 300 sq. mm stranded and compacted aluminium conductor. The large cross-sectional area allows it to carry high currents with minimal power loss. Compacting the strands creates a smoother, more uniform profile.
Conductor Screen: An extruded layer of a semi-conducting compound is applied over the conductor. This screen smooths out the electric field, preventing high-stress points and ensuring the longevity of the insulation.
XLPE Insulation: A thick layer of Cross-Linked Polyethylene (XLPE) insulation is extruded over the conductor screen. XLPE is chosen for its superior electrical properties, high thermal resistance (withstanding continuous temperatures up to 90C), and excellent mechanical strength, which are critical for high-voltage applications.
Insulation Screen: This layer, consisting of a semi-conducting compound and often a copper tape overlay, is applied over the insulation. It confines the electric field within the cable and provides a safe path for fault currents.
Inner Sheath: A layer of thermoplastic material (like PVC) is applied over the assembled cores. This inner sheath, or "bedding," protects the insulated cores and creates a uniform base for the armouring.
Armouring: For robust mechanical protection against crushing, impact, and underground damage, the cable is wrapped with galvanised steel strips. The armour also functions as an earth continuity conductor, enhancing safety.
Outer Sheath: The final protective layer is a thick PVC outer sheath (ST2 Grade). This sheath is highly durable and resistant to abrasion, moisture, chemicals, grease, and UV radiation, making the cable suitable for direct burial in the ground or installation in harsh environments.

Durable Aluminium Armoured Construction

This cable utilises an aluminium conductor with armoured layers, providing exceptional durability and mechanical strength for industrial power applications. The PVC shielding ensures long-term protection against environmental hazards and electrical interference, supporting uninterrupted operation in harsh conditions.

Precise Application and Installation

Engineered for industrial usage, the POLYCAB 11KV cable is ideal for high-voltage power distribution in factories, plants, and large infrastructure projects. Each reel offers a 500-meter continuous length, streamlining installations and reducing jointing requirements for enhanced electrical safety.

FAQs of HT Cable POLYCAB 11KV HT 3C* 300SQMM ALUMINIUM ARMOURED CABLE:

**Q: How is the POLYCAB 11KV HT 3C*300SQMM Aluminium Armoured Cable installed?**

A: Installation involves laying the cable through cable trays, ducts, or underground conduits, following industrial safety standards. Its armoured design provides extra protection during placement, and the 500-meter length allows for coverage of large distances in a single run, minimizing the need for multiple joints.

Q: What are the key advantages of using an aluminium conductor in this cable?

A: Aluminium conductors offer a lighter alternative to copper, reducing overall cable weight and facilitating easier handling. They provide efficient conductivity at a lower material cost, making them suitable for extensive industrial power distribution.

Q: When should this cable be selected for industrial projects?

A: Choose this cable for projects requiring high-voltage transmission, mechanical protection, and longevityespecially in environments where exposure to physical stress, moisture, or chemicals is anticipated.

Q: Where can I purchase or source the POLYCAB 11KV HT cable in India?

A: This cable is available through authorized distributors, manufacturers, suppliers, and traders across India. Local electrical stores and industrial suppliers carry the product, ensuring wide availability for project requirements.

Q: What is the process for ensuring safe usage and optimal performance of this cable?

A: Proper installation by certified professionals, adherence to voltage ratings, regular inspections, and maintenance are crucial. Use compatible connectors and ensure that the cable is not subjected to excessive bending, pulling, or exposure to corrosive materials.

Q: What benefits does the armoured PVC shield provide?

A: The armoured PVC shield enhances cable durability by protecting against physical impacts, rodent attacks, moisture ingress, and electrical disturbances, thereby extending the cables operational life and safety in demanding environments.
