600/1000V XLPE Insulated and Lead Sheathed Cables according to IEC 60502-1

    These cables are utilised for the transmission of electricity within low-voltage installation systems. Their suitability for installation extends to both indoor and outdoor environments, including cable ducts, subterranean settings, power and switching stations, local energy distribution networks, and industrial facilities, provided there is an absence of risk of mechanical damage. The lead sheath has been shown to provide enhanced resistance to aromatic hydrocarbons.

Conductors
The conductors shall be either of Class 1 or Class 2 of plain or metal-coated annealed copper or of plain aluminium or aluminium alloy, or of Class 5 of plain or metal-coated copper in accordance with IEC 60228.

Insulation
XLPE material and thickness shall be as per IEC 60502-1, rated for 90°C continuous operation.

Assembly / Inner Covering
    The inner coverings can be extruded or lapped. For cables with circular cores, except cables with more than five cores, a lapped inner covering is allowed only if the spaces between the cores are mostly filled. You can use a suitable binder before you put on the extruded inner covering. The material works well with the insulating material.
The materials used for inner coverings and fillers must be able to handle the cable's operating temperature and must also work well with the insulating material.
For halogen-free cables, the inner coverings and fillers must be made of halogen-free compounds.

Lead Sheath
lead or lead alloy and shall be applied as a reasonably tight-fitting seamless tube.

Seperation Sheath
The seperation sheath shall be of extruded PVC Type ST2 as per IEC 60502-1, or other material refer to outer sheath material.

Armour
Aluminum/galvanized steel/steel wires applied helically over the Inner Covering as per IEC 60502-1, or double aluminum/steel tapes and copper/tinned copper wire can also be manufactured upon request.

Outer Sheath
Outer sheath shall be of extruded PVC Type ST1/ST2 as per IEC 60502-1, Polyethylene type ST3/ST7, Halogen free compound ST8, Polychloroprene, chlorosulfonated polyethylene or similar polymers, type SE1 are also available on request.

    Interlocked armoured cable, commonly known as ‌lead sheathed cable‌, is a high-performance electrical cable engineered for extreme durability and environmental resistance.  Its core design features conductive copper or aluminum conductors insulated with materials like XLPE, surrounded by an interlocked metal armor—typically galvanized steel or lead—that provides unmatched mechanical protection against crushing, abrasion, and moisture.  The ‌lead sheath‌ adds a critical layer of impermeability, making these cables ideal for underground, marine, or industrial installations where corrosion resistance and longevity are non-negotiable.

    Lead sheathed armored cables‌ excel in harsh environments, including power grids, oil refineries, and offshore wind farms, where exposure to chemicals, water, or temperature fluctuations would degrade standard cables.  Their robust construction ensures compliance with IEC and IEEE safety standards, while the lead layer enhances grounding efficiency and fire resistance.  Compared to PVC-sheathed alternatives, ‌lead-clad cables‌ offer decades of reliable service with minimal maintenance, reducing lifecycle costs for critical infrastructure.

    For engineers prioritizing safety and ROI, ‌lead sheathed cable‌ systems deliver a future-proof solution, blending mechanical resilience with environmental adaptability.
