Features

01

Safety and reliability

The cable uses cross-linked polyethylene (XLPE) as the insulation material, which has excellent electrical insulation performance, can withstand high voltage, and has good heat resistance, ensuring the safe operation of the system in high temperature environments. XLPE also has strong fire resistance and anti-aging ability, reducing the risk of fire and failures caused by cable aging. In the armor design (such as steel belt armor), it has greater tensile strength and compressive resistance, which can effectively protect the cable from external mechanical damage, especially suitable for laying in an environment susceptible to external interference.

02

Superior electrical performance and high conductivity

The use of high-quality copper or aluminum conductors ensures that the cable has excellent conductivity, can efficiently transmit electricity, and reduce power loss. Copper conductors provide lower resistance and are suitable for high-load power systems, while aluminum conductors have more advantages in cost and weight. The high current carrying capacity of the cable is suitable for places where high-power current transmission is required, such as industrial equipment and high-load power systems.

03

Long service life and low maintenance cost

The cross-linked polyethylene insulation material of 1.8/3kV power cable has the characteristics of UV resistance, strong temperature resistance and oxidation resistance, which can effectively extend the service life of the cable. Even in extreme working environments, the cable can maintain a long reliable operation period, reducing the frequency of replacement and maintenance, and reducing maintenance costs.

04

Strong adaptability and multiple laying methods

This cable has strong adaptability and is suitable for underground power systems, air installation, cable trenches and pipelines. It can ensure safe power transmission even in narrow, harsh or humid environments. It has a wide operating temperature range and can operate stably between -15°C and +90°C.

05

Environmental protection and energy saving

The cable is made of environmentally friendly and non-toxic materials, meets modern green building and environmental protection standards, and is suitable for places with high environmental protection standards. The high efficiency of conductors and insulation materials greatly reduces energy loss in power transmission and improves the overall energy saving efficiency of the system.

06

Good mechanical protection and corrosion resistance

The outer sheath of the cable is made of corrosion-resistant materials such as PVC, which can effectively prevent chemical corrosion in the environment. It also has tensile and compressive strength, reducing the impact of external physical factors on the cable. Armored cables provide stronger mechanical protection and are suitable for use in high-risk environments, such as heavy industrial areas and mining areas.
