8.7/15kV 3 Core Copper LSZH SWA Cable for Underground Power Distribution | IEC 60502-2

8.7/15kV 3 Core Copper LSZH SWA Cable to IEC 60502-2 for Industrial Power Distribution

Product Overview

Zhongdong Cable Co., Ltd. manufactures medium voltage 8.7/15kV three-core copper conductor steel wire armoured (SWA) power cables with low smoke zero halogen (LSZH) sheath options for industrial power distribution, utility networks and infrastructure projects.

Designed for medium voltage electrical systems, this cable combines stranded copper conductors, XLPE insulation, metallic screening, steel wire armouring and an LSZH outer sheath. It provides electrical insulation, mechanical protection and reduced smoke and halogen acid gas emissions when the specified LSZH materials meet the relevant test requirements.

The 8.7/15kV three-core LSZH armoured power cable is suitable for projects requiring a compact three-phase cable arrangement, mechanical protection and specific fire-related material properties. It can be considered for industrial facilities, substations, commercial infrastructure and underground power distribution, subject to the applicable installation requirements.

As an experienced cable manufacturer with more than 20 years of manufacturing experience, Zhongdong Cable supplies power cables to electrical contractors, EPC companies, utility project buyers, cable distributors and industrial customers worldwide.

Key Features and Benefits

1. Medium Voltage Power Transmission

Rated at 8.7/15kV, the cable is designed for suitable medium voltage power distribution systems in industrial and infrastructure applications.

2. Stranded Copper Conductors

Copper conductors provide good electrical conductivity and are available in different nominal cross-sectional areas to meet project requirements.

3. XLPE Insulation

Cross-linked polyethylene insulation provides electrical insulation and thermal performance for medium voltage cable applications.

4. Steel Wire Armour (SWA)

Steel wire armouring provides mechanical protection for multicore cable installations where additional protection against external mechanical damage is required.

5. Low Smoke Zero Halogen (LSZH) Sheath

The specified LSZH compound is designed to reduce smoke generation and halogen acid gas emissions under relevant fire test conditions. Actual performance depends on the selected material and applicable test standards.

6. Three-Core Cable Construction

Three insulated cores are integrated into one cable assembly, supporting three-phase medium voltage power distribution while simplifying cable routing and installation.

7. Project-Specific Manufacturing

Conductor sizes, metallic screen requirements, sheath materials, cable markings, drum lengths and export packaging can be specified according to the project requirements.

Cable Construction

The typical construction of an 8.7/15kV three-core copper conductor LSZH SWA power cable includes the following layers:

Note: The final construction depends on the agreed cable design. The inner sheath, outer sheath and metallic screening materials must be confirmed against the applicable specification.

Technical Specifications

IEC 60502-2 is a reference standard for medium voltage extruded-insulation power cables. LSZH properties and any additional flame-retardant or fire-performance requirements must be specified and verified separately where applicable.

Frequently Asked Questions

What is an 8.7/15kV three-core LSZH SWA cable?

It is a medium voltage power cable rated 8.7/15kV, featuring three copper conductor cores, XLPE insulation, metallic screening, steel wire armouring and a specified low smoke zero halogen sheath construction.

What does LSZH mean in medium voltage cables?

LSZH stands for Low Smoke Zero Halogen. LSZH compounds are designed to limit smoke generation and halogen acid gas emissions during fire exposure. Specific performance should be verified against the applicable material and fire test standards.

Does IEC 60502-2 guarantee LSZH performance?

No. IEC 60502-2 covers relevant construction and testing requirements for medium voltage extruded-insulation power cables. LSZH performance and additional fire-related properties must be addressed through the appropriate material specifications and applicable tests.

Why use steel wire armour for a three-core medium voltage cable?

Steel wire armour provides mechanical protection and is commonly used for multicore medium voltage cable designs. The final armour construction should be selected according to the installation conditions and project requirements.

What conductor sizes are available?

Conductor sizes can be selected according to the project specification, required current-carrying capacity, installation method and applicable electrical design criteria. Contact Zhongdong Cable with your required cross-section and quantity for a quotation.

Can this cable be used for underground installation?

It can be considered for suitable underground installations when the cable construction meets the project's mechanical, environmental, electrical and regulatory requirements. Additional water-blocking or moisture-resistance features may be needed for certain environments.

Can you provide technical datasheets and quotations?

Yes. Please provide the rated voltage, conductor cross-section, required standard, cable length, total quantity and delivery destination. Our team can review the requirements and prepare a quotation based on the agreed cable design.
