XLPE Insulated Power Cable

Application

The normal operating temperature of XLPE insulated power cable conductors is 90°C. XLPE cables not only have excellent electrical properties, high operating temperature, and large transmission capacity, but also have the advantages of simple structure, small outer diameter, light weight, convenient installation and use, and unrestricted laying and falling. XLPE insulated cables are divided into low voltage, medium voltage and high voltage according to the use environment. They are usually laid indoors, outdoors, in pipelines, cable trenches and loose soil. They can withstand a certain laying traction, but they cannot withstand external mechanical forces.It is generally applied to the fields including power, construction, mines, metallurgy, petrochemical indusry and communication in complete replace of oil immersed paper insulated power cable and in partial replace of PVC insulated power cable. Some common applications of XLPE insulated power cables include:

Underground power transmission and distribution:

XLPE insulated power cables are widely used for the underground transmission and distribution of electrical power. They are capable of withstanding high voltage and high current levels, and can be installed in a variety of environments, including urban areas, industrial facilities, and remote locations.

Overhead power transmission:

XLPE insulated cables can also be used for overhead power transmission, where they are suspended from towers or poles. This is a common practice in rural areas, where there are long distances between power generation sources and end-users.

Industrial applications:

XLPE insulated power cables are commonly used in industrial applications, such as mining, oil and gas, and manufacturing. They are suitable for use in harsh environments, where they may be exposed to high temperatures, chemicals, and abrasion.

Renewable energy projects:

XLPE insulated power cables are used in renewable energy projects, such as wind and solar power installations, where they are used to transmit power from the generation source to the grid.

Marine and offshore applications: XLPE insulated power cables are commonly used in marine and offshore applications, such as oil rigs, ships, and submarines. They are designed to withstand harsh conditions, including saltwater corrosion, extreme temperatures, and high pressures.

Construction

• Conductors: Solid or stranded aluminum conductors, stranded copper conductors, class 2 copper or aluminum conductors to BS EN 60228 (formerly BS 6360), compacted or segmented strands.
• Cross-sectional area: usually 35mm2 to 630mm2 (medium voltage XLPE power cables), 150-800mm2 (high voltage XLPE power cables)
• Insulation: XLPE (often used for medium voltage cables) or EPR (often used in marine or marine applications due to its flexibility).
• Metal Shield: Concentric copper wire shield, aluminum foil laminate, extruded lead alloy sheath.
• Armoring: Aluminum tape armoring is mainly used for single-core cables, and galvanized steel wire armoring is mainly used for multi-core cables.
• Outer Sheath: Cable sheath materials include PVC, EPR, LSZH, HDPE (High Density Polyethylene) (specify when ordering, other options are available) to meet different environmental requirements.
• Short circuit temperature: +250 °C, operating temperature: -30 °C to 90 °C

Standards

The products are mainly complying with IEC 60502 standard, also can be produced according to OEM requirements and other standards, such as BS standard, DIN standard, ASTM standard, etc.

Voltage grade is up to 35kv, cross-section area can be up to 400 sqmm (copper or alumimum conductor). Conductor long-time operating temperature is 90℃. In short circuit, conductor highest temperature should be not more than 250℃
