High Voltage Power Cable 35kV XLPE Insulated Steel Armored Copper Conductor Power Cable

Product Introduction

The XLPE Insulated Armored Power Cable is developed for medium and high-voltage power transmission applications where electrical stability, mechanical strength, and long-term service performance are required. Featuring a multi-layer structure of copper conductor, XLPE insulation, metallic shielding, armored protection, and outer sheath, this cable provides dependable operation in complex installation environments.

Designed for fixed power distribution systems, the cable is commonly installed underground, in cable trenches, pipelines, industrial facilities, and energy infrastructure projects. The armored construction improves resistance against external mechanical stress, while the XLPE insulation system ensures stable insulation performance under high electrical loads.

Available in different voltage grades, conductor sizes, and core configurations, the cable can be customized according to specific project requirements.

FAQ

Q1: What is XLPE insulated armored power cable used for?

A: It is mainly used for medium and high-voltage electrical transmission systems, including underground networks, industrial power supply, substations, and renewable energy projects.

Q2: Why is XLPE insulation commonly used in power cables?

A: XLPE provides excellent electrical insulation performance, high temperature resistance, low dielectric loss, and good resistance to moisture and aging, making it suitable for modern power transmission systems.

Q3: What is the function of the armored layer?

A: The armor protects the internal cable structure from mechanical damage caused by external pressure, impact, and underground installation conditions.

Q4: What is the difference between steel tape armor and steel wire armor?

A: Steel tape armor mainly improves resistance against compression and external pressure, while steel wire armor provides higher tensile strength for applications requiring stronger mechanical protection.

Q5: Can this cable be used for direct underground burial?

A: Yes. Armored versions are commonly selected for underground burial projects because they provide additional mechanical protection. Installation requirements should follow local electrical regulations.

Q6: What voltage levels can be manufactured?

A: The cable can be produced for various voltage grades, including 6kV, 10kV, 15kV, 20kV, and 35kV systems.
