LSZH XLPE Power Cable – Low Dielectric Loss & 90°C Continuous Rating
Our LSZH XLPE power cable is built on a peroxide cross-linked polyethylene insulation system that raises the continuous operating temperature to 90°C and withstands a 250°C short-circuit peak. The low smoke halogen-free (LSZH) sheath together with a low dielectric loss compound delivers stable, high-efficiency power transmission and a designed service life of 40 years or more – ideal for public buildings, tunnels, subways and other locations where fire safety and clean combustion are mandatory.
Key Features
- 90°C continuous rating, 250°C short-circuit withstand – higher current-carrying capacity than PVC-insulated cable.
- Low dielectric loss, high transmission efficiency – the dielectric loss tangent stays low and is barely affected by temperature.
- Moisture, chemical & UV resistance – resistance to acids, alkalis, oils, humidity and sunlight exposure.
- Long service life ≥40 years – the three-dimensional cross-linked network resists ageing and environmental stress cracking.
- LSZH / FR / NH customizable – choose low smoke halogen-free, flame-retardant or fire-resistant construction.
- Armored option for direct burial – optional steel tape or steel wire armour for direct-burial installation.
- CE / IEC certified – manufactured to IEC 60502 and CE requirements.
Applications
- Public buildings, offices, hospitals and shopping centres
- Tunnels, subways and other high fire-safety zones
- Low-voltage distribution networks and power transmission
- Outdoor, duct and direct-burial installation (armoured type)
The versatility of XLPE insulation allows it to be used in a wide range of electrical systems.
Power Distribution
XLPE cables are widely used in low- and medium-voltage distribution systems connecting substations, transformers, switchgear, and electrical loads.
Their electrical and thermal characteristics make them suitable for demanding continuous-service applications.
Industrial Facilities
Manufacturing plants, refineries, mining operations, processing facilities, and other industrial environments often use XLPE power cables for fixed power distribution.
The cable construction may be modified with specialized sheaths, armor, shielding, or chemical-resistant materials according to the installation environment.
Building and Infrastructure Projects
Large commercial buildings, transport infrastructure, airports, data facilities, and public utility projects can use XLPE insulated power cables where dependable power distribution is required.
Fire performance and low-smoke requirements may require the selection of additional sheath and insulation compounds beyond the basic XLPE system.
Renewable Energy
Solar farms, wind projects, energy storage facilities, and grid connection infrastructure frequently require cables capable of operating under demanding environmental and thermal conditions.
Cable selection must consider current fluctuations, installation exposure, temperature, route length, and connection requirements.
Underground Electrical Networks
XLPE cables are widely used in underground power systems because they can be designed for installation in direct-buried routes, ducts, tunnels, and other protected infrastructure.
Thermal conditions remain a critical consideration. Soil thermal resistivity, burial depth, cable spacing, and surrounding materials can significantly affect current-carrying capacity.

FAQ
Q: What is the continuous and short-circuit temperature of this cable?
A: The long-term continuous rating is 90°C, and it withstands a short-circuit temperature of 250°C.
Q: Why does the cable have low dielectric loss?
A: The XLPE compound keeps the dielectric loss tangent very low and stable across temperature, ensuring high transmission efficiency.
Q: Is the sheath available in LSZH, flame-retardant or fire-resistant versions?
A: Yes, LSZH, FR (flame retardant) and NH (fire resistant) constructions are all customizable.
Q: What is the expected service life?
A: The designed service life is 40 years or more under normal operating conditions.
Q: Can it be installed by direct burial?
A: Yes, the armoured option (steel tape or steel wire) supports direct-burial installation.
