Foshan Cables, Yjv
Foshan cables, Foshan cable manufacturer Guangdong Shuangli Cable Co., Ltd. supplies NHYJV 70-square medium-voltage cross-linked power cables and NHYJ-70V fire-resistant power cables produced by Foshan Shuangli Cable Co., Ltd.
The cross-linked polyethylene insulated cables of Guangdong Shuangli Cable Co., Ltd. use chemical or physical methods to transform the polyethylene molecules of the cable insulation from a linear molecular structure to a three-dimensional network molecular structure. That is, the thermoplastic polyethylene is transformed into thermosetting cross-linked polyethylene, which greatly improves its heat resistance and mechanical properties, reduces its shrinkage, makes it no longer melt after being heated, and maintains excellent electrical properties.
Shuangli cross-linked polyethylene insulated cables have four major properties:
1. Heat resistance: XLPE with a network three-dimensional structure has excellent heat resistance. It will not decompose or 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 characteristics of PE, and the insulation resistance is further increased. Its dielectric loss tangent value 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 shortcoming that PE is prone to cracking due to environmental stress.
4. Chemical resistance: XLPE has strong resistance to acids, alkalis and oils. Its combustion products are mainly water and carbon dioxide, which cause less harm to the environment and meet the requirements of modern fire safety.
Guangdong Shuangli Cable Co., Ltd. is widely used in State Grid, China Southern Power Grid, power, transportation, urban construction and other fields. Its products are well - sold at home and abroad, deeply trusted by users, and have won unanimous recognition and praise from users and colleagues in the cable industry.
