Product Introduction

Features

1. Heat resistance: XLPE with net-like three-dimensional structure has very excellent heat resistance. It will not decompose and carbonize below 300°C, the long-term working temperature can reach 90°C, and the thermal life can reach 40 years.

2. Insulation performance: XLPE maintains the original good insulation properties of PE, and the insulation resistance further increases. Its dielectric loss tangent is very small and is not greatly affected by temperature.

3. Mechanical properties: Due to the establishment of new chemical bonds between macromolecules, the hardness, stiffness, wear resistance and impact resistance of XLPE are all improved, thus making up for the shortcomings of PE that are susceptible to environmental stress and cracks.

4. Chemical resistance: XLPE has strong acid and alkali resistance and oil resistance, and its combustion products are mainly water and carbon dioxide, which is less harmful to the environment and meets the requirements of modern fire safety.

110kV XLPE insulated power cable features abundant merits of light structure, high intensity medium, low lossof medium, durable in aging, easy for installation, laying without limit of fall etc. 110kV XLPE insulated powercable can be used in high voltage power transmission and distribution lines especially. The application of thiskind of cable in the underground municipal transforming and transmitting lines are increasing.
