1. High Electrical Properties XLPE almost completely maintains PE’s inherent high electrical properties, such as high breakdown strength, large insulation resistance, small dielectric number, and low dielectric loss tangent value. 2.High Transmission Capacity Because XLPE is highly heat-resistant and aging-resistant, tanδ value is small, and the long-term allowable operating temperature can reach 90℃, its transmission capacity is greatly improved. 3. Small Weight per Unit Length XLPE insulated cable does not require a metal jacket, and the density of XLPE is small, so the weight of the cable per unit length is small, making it convenient to lay. 4. Simple Laying XLPE insulated cable is a dry-insulated cable and does not contain impregnation, so it does not occur as the aging phenomenon caused by the downward flow of impregnation in paper insulated power cables, which makes it easy to high drop and vertical laying. 5. Good resistance to chemicals.   Want to know more about XLPE insulated cable please click here.

Characteristics of Different Laying Methods of Power Cables Direct Burial Laying Advantages: Small investment, convenient construction, and good heat dissipation conditions. Disadvantages: Easy to be damaged by mechanical forces, chemical or electrochemical corrosion of the surrounding soil, termite and rat hazards, difficult to find faults and repair cables. Applicable environment: There are no obstacles underground. The soil does not contain severely corrosive media such as acid, alkali and salt. And the cable number is less.

What are the functions of cable outer sheath and inner sheath? What are the main properties of the insulation layer of electric cables? What regulations should be followed when selecting the cross-section of electric cables?

XLPE insulated cables and PVC insulated cables are basically the same in function, but there are obvious differences in performance, applicable environment etc.The insulation performance of XLPE insulated cables is better than that of PVC .
