Product Overview

Insulated & Fire-Resistant Power Cables

These PVC-insulated and fire-resistant power cables are designed for permanent installation in power transmission and distribution networks, operating at 50Hz AC with voltages up to 6kV.

Key Specifications:

• Operating Temperature: Maximum continuous conductor temperature of 70°C.
• Short-Circuit Rating: Conductor temperature must not exceed 160°C during a short-circuit event of up to 5 seconds.
• Installation: Can be installed vertically without level restrictions. Minimum ambient temperature for installation is 0°C.

Standard Constructions:
The cables are available in various configurations, including:

• Conductor: Copper or Aluminum (Cu/Al)
• Insulation: PVC or XLPE
• Armouring: Options include Steel Wire Armour (SWA), Steel Tape Armour (SWT), Aluminum Wire Armour (AWA), and Aluminum Tape Armour (AWT).
• Sheath: PVC

Cable Construction & Technical Specifications

This cable is constructed with a robust, layered design for high performance and reliability.

Layer-by-Layer Construction:

• Metallic Screen: Available in configurations of copper wires, copper tape, or a combination of both.
• Inner Sheath: Composed of PVC (Polyvinyl Chloride).
• Armouring: Features Steel Tape Armour (SWA). For single-core cables, a non-magnetic armour material is used to minimize energy losses.
• Outer Sheath: A durable outer layer of PVC (Polyvinyl Chloride).

Advanced Manufacturing Process:
The core components—the conductor screen, XLPE insulation, and insulation screen—are manufactured using a triple extrusion process on a Continuous Vulcanization Line. This state-of-the-art method ensures:

• Perfectly clean interfaces between the insulation and semiconductive layers.
• A construction that is free from Partial Discharge (PD).
• Exceptionally high operational reliability and longevity.

Key Technical Parameters:
For detailed performance data, please refer to the following tables:

• Table 1-1: Cable conductor DC resistance.
• Table 1-2: Partial discharge test results.
• Table 1-3: AC voltage withstand test specifications.
• Table 1-4: Rated voltage, core numbers, and nominal cross-sectional areas.

Key Improvements in This Version:

Grammar and Spelling: Corrects “Amoured” to “Armouring” and “Semi-Conductive” to the more standard “semiconductive.”

Professional Tone: Uses standard industry language (e.g., “configurations,” “state-of-the-art method,” “robust, layered design”).

Clarity and Flow: Sentences are restructured to be more direct and easier to read.

Logical Grouping: Information is organized under clear headings (Construction, Manufacturing, Parameters).

Explained Benefits: The technical advantage of the “triple extrusion method” is clearly stated (prevents Partial Discharge, ensures reliability).
