Product Overview

The High Voltage XLPE Insulated Armored Power Cable is designed for reliable energy transmission in medium and high-voltage electrical networks. According to the cable structures shown, the product adopts a multi-layer construction including copper conductor, XLPE insulation, metallic shielding layer, steel tape or steel wire armor, and protective outer sheath, providing excellent electrical performance and strong mechanical protection.

This type of power cable is widely applied in underground power distribution, industrial facilities, substations, renewable energy projects, and urban electrical infrastructure where safety, durability, and stable power delivery are required.

With excellent insulation performance, high current-carrying capacity, and resistance against mechanical impact, the cable provides a long-term solution for fixed power transmission applications.

Product Structure

Based on the cable cross-section structure, the main layers include:

1. Copper Conductor

The cable uses high-conductivity copper conductors to ensure efficient current transmission with low electrical resistance. The stranded conductor structure improves flexibility and installation convenience.

2. XLPE Insulation Layer

Cross-linked polyethylene (XLPE) insulation provides:

• High dielectric strength
• Excellent thermal stability
• Low dielectric loss
• Strong resistance to moisture and aging

It is suitable for long-term operation under medium and high-voltage conditions.

3. Insulation Shield & Metallic Screen

The shielding layer helps control the electric field distribution around the insulation and improves cable safety during operation.

4. Armoring Layer

Depending on project requirements, the cable can be equipped with:

• Steel tape armor
• Steel wire armor

The armor layer enhances resistance against mechanical damage, external pressure, and underground installation stress.

5. Outer Sheath

The outer sheath protects the internal cable structure from moisture, corrosion, abrasion, and environmental influences.

Product Applications

1. Underground Power Distribution Networks

Used for urban electrical grids, residential communities, commercial buildings, and municipal power distribution systems where overhead lines are unsuitable.

2. Industrial Power Supply Systems

3. Renewable Energy Projects

Suitable for solar farms, wind power stations, and energy storage facilities to transmit generated electricity to substations or distribution networks.

4. Electrical Substations

Used for connecting transformers, switchgear, and power distribution equipment in medium and high-voltage substations.

5. Infrastructure Construction

Commonly installed in:

• Airports
• Rail transit systems
• Data centers
• Large commercial complexes
• Public facilities

where reliable power transmission is essential.

FAQ

Q1. What is an XLPE insulated armored power cable?

A: It is a power transmission cable that uses XLPE as the insulation material and adds a metallic armor layer for mechanical protection. It is mainly used in medium and high-voltage electrical systems.

Q2. What is the purpose of the armor layer?

A: The armor layer protects the cable from external mechanical damage, pressure, impact, and underground installation risks, allowing safer direct burial applications.

Q3. Why is XLPE used for high voltage cables?

A: XLPE provides excellent insulation strength, low dielectric loss, high temperature resistance, and stable electrical performance, making it suitable for high voltage power transmission.

Q4. Can this cable be buried underground directly?

A: Yes. Armored versions are commonly designed for underground installation. The exact installation method depends on cable type, local regulations, and project requirements.

Q5. What voltage levels are available?

A: Common voltage ratings include 6kV, 10kV, 15kV, 20kV, 26kV, and 35kV. Customized voltage levels can also be produced according to customer specifications.

Q6. What is the difference between steel tape armor and steel wire armor?

A: Steel tape armor provides strong protection against compression and is commonly used for underground applications. Steel wire armor offers higher tensile strength and is suitable for installations requiring greater mechanical pulling resistance.
