Insulation tube: Ensure power safety and efficiency

What is insulation tube?

Insulation tube is a tubular material used for cable protection. It is usually used to protect cables, wires, cable trays and other lines. The function of insulation tube is to isolate moisture, solvents, corrosive gases and liquids in the air, increase the insulation strength of the cable, and extend the service life of the cable. There are many types of insulation tubes, and the common ones are made of PVC, PE, PET and other materials.

Characteristics of insulation tubes

‌Electrical properties‌: Insulation tubes have high insulation resistance and low dielectric constant, which can effectively isolate the charge between different dielectrics and ensure the normal operation of electronic components. In addition, they can remain stable in harsh environments such as high voltage, high temperature, and high humidity, and are not prone to aging and cracking.

‌Physical properties‌: Insulation tubes usually have a smooth and flat surface. And they are not easy to deform and have strong chemical corrosion resistance. Through special production processes and material formulations, their physical properties such as density, hardness, toughness, and wear resistance can be ensured, thereby ensuring the high reliability and long life of the insulation system.

‌Chemical properties‌: Some insulation tube materials themselves do not contain chemicals that are harmful to the environment. And no harmful gases and pollutants are emitted during the manufacturing process. Therefore, they will not have a negative impact on the environment during use and have a high environmental value.

Specific applications of insulation tubes in the power industry

Insulation tubes are widely used in the power industry, mainly including the following aspects:

Cable protection

Insulation tubes are widely used as outer protective tubes for power cables to prevent cables from being damaged by environmental factors (such as sun and rain, mechanical damage, etc.) or electrical faults. This helps to ensure the normal operation of the power system and reduce power outages and maintenance costs caused by cable faults.

Overhead line protection

In overhead lines, insulation tubes are used to protect wires from erosion by natural environments such as wind, rain, and snow, as well as to prevent damage to the lines by external factors such as bird damage and tree barriers. This helps to improve the reliability and safety of overhead lines.

Electrical equipment protection

Insulation tubes are also used as control tubes and protective tubes for electrical equipment to provide additional insulation protection for the equipment. This helps prevent electrical short circuits and electric shock accidents and ensures the safe operation of the equipment. For example, in distribution boxes, insulation tubes are used as shell materials to isolate and protect the internal electrical components from interference and damage from the external environment.

Special environmental applications

In high temperature, humid or corrosive environments, insulation tubes can maintain their structural stability and insulation performance, providing effective protection for power equipment. For example, in high temperature environments, insulation tubes can prevent wires and cables from being damaged due to thermal expansion and contraction; in humid environments, insulation tubes can prevent water vapor from corroding electrical equipment; in corrosive environments, insulation tubes can resist the erosion of chemicals and protect cables and equipment from damage.

As an indispensable component in the power system, the insulation tube provides a solid guarantee for power safety and efficiency with its excellent insulation performance, electrical performance, physical performance and other characteristics. It is an invisible guardian in the process of power transmission and distribution, silently guarding the stable operation of the power system and the efficient use of energy. Therefore, we should fully realize the importance of insulation tubes and strengthen the research and improvement of their performance to better serve the safe and efficient operation of the power system.
