This article will explain in detail the definition, characteristics, and application scenarios of YJE cables, and attach the hot topics and hot content on the entire network in the past 10 days to help readers better understand this cable type.
1. Definition of YJE cable
YJE cable is a cross-linked polyethylene insulated polyolefin sheathed power cable, where "YJ" stands for cross-linked polyethylene insulation and "E" stands for polyolefin sheath. This cable has excellent electrical and mechanical properties and is widely used in power transmission and distribution systems.
2. Characteristics of YJE cable
| Features | Description |
|---|---|
| High temperature resistance | The cross-linked polyethylene insulation layer can withstand higher temperatures, and the long-term operating temperature can reach 90°C. |
| Corrosion resistant | Polyolefin jacket has good chemical resistance. |
| High mechanical strength | The cable has a solid structure and excellent tensile and compression resistance. |
| Environmentally friendly | The material is non-toxic, halogen-free and meets environmental protection requirements. |
3. Application scenarios of YJE cable
YJE cables are widely used in the following fields:
| Application areas | Specific use |
