What is XLPE cable?
The cross-linked polyethylene(XLPE) insulated cable uses peroxide cross-linking method to change the polyethylene molecule from a linear molecular structure to a three-dimensional network structure, and from a thermoplastic material to a thermosetting material. The working temperature is increased from 70°C to 90°C. Improve the current carrying capacity of the cable;
What is the advantages of XLPE cable ?
1. Heat resistance: MPE with a net-like three-dimensional structure has 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 is further increased. The tangent of the media loss angle is very small, and it 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 have been improved, thus making up for the shortcomings of PE cable being vulnerable to environmental stress and cracking;
4. Chemical resistance: XLPE has strong acid and alkali resistance and oil resistance. Its combustion products are mainly water and carbon dioxide, which are less harmful to the environment and meet the requirements of modern fire safety.
what’s the XLPE useage ?
Cross-linked polyethylene insulated cables are suitable for power distribution networks, industrial installations or other fields that require large-capacity power consumption. They are used for fixed laying on power transmission and distribution lines with AC 50Hz and rated voltages of 6kV to 35kV. The main function is to transmit electrical energy.
Cross-linked polyethylene insulated flame-retardant cables have the function of preventing fire from spreading in the cable circuit, can avoid the expansion of fire accidents and reduce losses, and are suitable for places with high cable laying density such as subways, tunnels, and high-rise buildings.
Is XLPE low smoke ?
The halogen-free low-smoke flame-retardant XLPE insulated cable( LSOH cable) has excellent flame-retardant properties, and the sheath material does not contain halogen, which can ensure that only a small amount of toxic and corrosive gases are released during combustion, and it has the characteristics of less smoke. An environmentally-friendly new product, with superior electrical properties, heat resistance, chemical resistance, environmental stress cracking resistance, aging resistance, and long service life.
