The advantages of XLPE cable mainly include excellent electrical insulation performance, mechanical performance, heat resistance, portability, and environmental friendliness.
XLPE cable have excellent electrical insulation performance, with lower dielectric loss than paper insulation and PVC insulation, and smaller capacitance. Therefore, they can reduce charging current and ground fault current even without an effective star grounding system. In addition, the anti-aging characteristics and thermal deformation of XLPE cable determine that it can allow large current to pass through 1 under normal operating temperature (90 ℃), short time fault (130 ℃) and short circuit (250 ℃).
In terms of mechanical performance, XLPE cable have high tensile strength and wear resistance, and can maintain good physical condition in various environments. Its heat resistance is also excellent, with a long-term allowable working temperature of 90 ℃, which is higher than the 70 ℃ of PVC cables and suitable for high temperature environments.
XLPE cable also have the advantages of lightweight, small diameter, easy installation and laying, simple accessory joints, and easy handling and transportation. In addition, due to the absence of oil, there is no need to consider route issues during installation, and there will be no situation where oil spills and prevents installation.
Finally, XLPE cable also performs well in terms of environmental protection. Although some by-products may be generated during the production process, it is an environmentally friendly material that can be recycled and reused, reducing its impact on the environment
