240mm² Single Core XLPE Insulated Power Cable | 0.6/1kV | IEC 60502-1

Product Overview

The 240mm² Single Core XLPE Insulated Power Cable is a low-voltage (0.6/1kV) energy cable designed for fixed installation in power distribution networks, industrial facilities, commercial buildings, and infrastructure projects. Fully compliant with IEC 60502-1, this cable delivers superior electrical performance, thermal stability, and mechanical durability.

Key Applications:

• Power supply for industrial plants, hotels, hospitals, schools, and tunnels

• Energy distribution in power plants and data centers

• Indoor/outdoor installation in cable trays, conduits, or direct burial (with armouring)

• Transformer and switchgear connections

Construction Details – Layer by Layer

This cable is built with the following layers, from innermost to outermost:

1. Conductor – Class 2 plain annealed copper, circular stranded and compacted for reduced diameter and enhanced conductivity. Meets IEC 60228.

2. Conductor Screen – A semi-conducting layer bonded to the insulation, ensuring a uniform electrical field distribution and preventing partial discharges.

3. XLPE Insulation – Cross-linked polyethylene, a thermosetting material with superior dielectric strength, low loss, and excellent thermal aging resistance. Rated for 90°C continuous operation and 250°C under short-circuit conditions.

4. Insulation Screen – A removable or bonded semi-conducting layer for stress control at the insulation surface.

5. Outer Sheath – PVC (standard) or LSZH (low smoke zero halogen, optional). Provides mechanical protection, flame retardancy, and UV resistance. Black or custom colors available.

Standards & Certifications

This cable is manufactured and tested in strict accordance with the following international standards:

• IEC 60502-1 – Power cables with extruded insulation for rated voltages 1 kV to 3 kV (design and testing)
• IEC 60228 – Conductors of insulated cables (Class 2 stranded copper)
• IEC 60332-1-2 – Flame retardancy for single vertical cable
• IEC 60332-3-22 (Cat. A/C) – Flame retardancy for bunched cables (optional)
• IEC 60754-1/2 – Halogen gas emission testing (for LSZH version)
• IEC 61034-2 – Smoke density measurement (for LSZH version)

Why Choose This Cable?

• Higher Current Rating – XLPE insulation allows 90°C continuous operation, compared to only 70°C for PVC. This means you can achieve higher power transmission with the same conductor size, or use a smaller conductor for the same load.
• Low Transmission Losses – With a maximum DC resistance of just 0.075 Ω/km at 20°C, this cable minimizes energy losses over long distances.
• IEC 60502-1 Compliance – Internationally recognized and bankable. This standard is accepted by utilities, engineers, and government agencies worldwide, making your project inspection-ready.
• Flexible Installation – The single core design allows for easy routing in confined spaces. Suitable for trefoil or flat formation, in cable trays, conduits, or ladder racks.
• Enhanced Fire Safety – The flame-retardant PVC sheath meets IEC 60332-1-2. For applications requiring low smoke and zero halogen emissions, an LSZH version is available.

Applications & Suitable Industries

• Industrial Facilities – Power distribution to motors, control panels, and heavy equipment in manufacturing plants, refineries, and processing facilities.
• Commercial Buildings – Main feeders, risers, and sub-main circuits in hotels, office towers, shopping malls, and hospitals.
• Infrastructure Projects – Tunnels, airports, metro systems, data centers, and stadiums.
• Power Generation – Auxiliary power circuits in power plants, substations, and renewable energy installations.
• Renewable Energy – Solar farm collection systems and wind turbine feeder cables.

Installation Suitability

• Indoor (cable trays, conduits): Excellent

• Outdoor with direct sunlight: Yes – requires UV-stabilized PVC sheath

• Direct burial: Yes – with additional armouring (SWA/STA) or mechanical protection

• Wet locations: Yes – XLPE insulation is water-resistant

Frequently Asked Questions (FAQ)

Q: What is the difference between XLPE and PVC insulated cables?

A: XLPE insulation allows a higher continuous operating temperature (90°C vs. 70°C for PVC), which translates to a higher current-carrying capacity for the same conductor size. XLPE also offers better thermal aging resistance, lower dielectric losses, and longer service life. For the 240mm² size, this means you can safely carry over 600A in air with XLPE, significantly more than a PVC-insulated cable of the same conductor.

Q: Can this cable be used for direct burial?

A: The standard PVC sheath provides mechanical protection suitable for conduit or tray installation. For direct burial, we strongly recommend an armoured version (SWA – Steel Wire Armour or STA – Steel Tape Armour) to protect against excavation damage, rodent attack, and soil pressure. Please contact us for armoured options.

Q: Is LSZH (Low Smoke Zero Halogen) version available?

A: Yes. Upon request, we can supply this cable with an LSZH outer sheath. During a fire, LSZH emits minimal smoke and no toxic halogen gases (such as hydrogen chloride), making it ideal for tunnels, underground railways, airports, data centers, and any confined or poorly ventilated spaces.

Q: What is the maximum pulling tension for installation?

A: The maximum recommended pulling tension is 50 N/mm² of the total conductor cross-section. For a 240mm² copper conductor, this is approximately 12,000 N (about 1,220 kg-force or 2,690 lbs). Always use a pulling swivel and avoid exceeding the minimum bending radius during installation.

Q: Can you provide third-party inspection before shipment?

A: Absolutely. We welcome independent third-party inspectors from SGS, BV, TUV, Intertek, or any agency you designate. Inspectors may witness the entire manufacturing process, witness routine testing, verify dimensions, and confirm packaging before release. Inspection costs are typically borne by the buyer unless otherwise negotiated.

Q: What is the typical lead time for this cable?

A: For standard 240mm² single core XLPE/PVC cable, lead time is typically 15–25 working days after receipt of deposit and confirmation of specifications. Stock items may be available for immediate dispatch. Please inquire for current stock levels.
