Steel strip armored cross-linked power cable is a type of cable widely used in power transmission and building electrical engineering. Its full name is copper core cross-linked polyethylene insulated PVC sheathed steel strip armored power cable. The following is the detailed introduction about steel strip armored cross-linked power cable:

I. Product overview

Definition: Copper core cross-linked polyethylene insulated PVC sheath steel tape armored power cable is composed of copper core conductor, cross-linked polyethylene insulation layer, PVC sheath and steel tape armor layer.

Structure: The cable has a multi-layer structure, including the inner copper conductor, the middle cross-linked polyethylene insulation layer, the outer PVC sheath and the outer steel strip armor layer.

2. Product features

Conductive performance: copper core conductor has good conductive and thermal conductivity, suitable for long distance transmission and large current load.

Insulation performance: The cross-linked polyethylene insulation layer has good heat resistance and chemical corrosion resistance, which can effectively protect the conductor.

Sheath performance: PVC sheath has good wear resistance and weather resistance, can effectively prevent the external medium to the cable erosion.

Armour performance: The steel strip armour layer has good mechanical strength and resistance to external forces, suitable for underground laying and exposure in harsh environments.

3. Usage characteristics

Working temperature: the long-term allowable working temperature of cable conductor is not more than 90℃, and the maximum working temperature during short circuit is not more than 250℃ (the longest duration is not more than 5 seconds).

Installation temperature: the installation temperature of cable should not be lower than 0℃.

Bend radius: The minimum bend radius of a single core cable is 15 times the outer diameter of the cable, and the minimum bend radius of a multi-core cable is 12 times the outer diameter of the cable.

4. Scope of application

Building electrical engineering: Copper core cross-linked polyethylene insulated PVC sheathed steel strip armored power cable is often used in building electrical engineering, such as building distribution, indoor wiring, etc., for the transmission of electricity and signals.

Industrial power transmission: suitable for industrial power transmission systems, such as factories, mines, docks and other places for power supply.

Urban power grid construction: can be used for the construction and transformation of urban power grid, used to transmit medium and low voltage power and communication signals.

5. Laying method

Copper core cross-linked polyethylene insulated PVC sheathed steel tape armored power cable is an armored cable, which can be buried directly, laid in pipes, laid in bridge trays, trench supports and other ways. The specific laying method should be selected according to the design requirements and actual conditions.

6. Notes

During transportation and installation, mechanical damage to cables should be avoided.

Cables should not be stored in the open air, and cable reels should not be placed flat.

When laying, ensure that the bending radius of the cable is not less than the specified value to avoid damage to the cable.

In summary, copper core cross-linked polyethylene insulated PVC sheathed steel tape armored power cable is an excellent and widely used type of power cable. In practical applications, appropriate cable specifications and installation methods should be selected based on specific requirements and environmental conditions to ensure the safety and reliability of power transmission.
