Argument details: XLPE (cross-linked polyethylene) and XLPO (cross-linked polyolefin) are both commonly used insulating materials in automotive cables, each with unique characteristics and advantages. The following are the specific differences between these two materials in automotive cables:
1. Basic properties XLPE (cross-linked polyethylene) Structure: XLPE is a polyethylene molecule that is transformed from a linear structure to a mesh structure by chemical or physical methods, thereby improving its heat resistance and mechanical properties. Density: The insulation specific gravity of XLPE is 1.2g/cm3, which is relatively light. Electrical properties: XLPE has excellent electrical properties, low dielectric loss, and low capacitance, and is suitable for the insulation layer of various wires and cables. Heat resistance: The long-term allowable operating temperature of XLPE can reach 90°C, and it can still maintain an elastic state at 130°C, and its interception capacity can be increased by about 25% compared to PVC insulated cables of the same cross-section. Safety: XLPE does not contain halogens, so it will not decompose toxic gases at high temperatures, which is relatively safe. XLPO (cross-linked polyolefin) Structure: XLPO is similar to XLPE, and its performance is also improved by cross-linking reaction. Mechanical and physical properties: The mechanical and physical properties of XLPO are similar to those of XLPE. Flame retardancy: XLPO has excellent halogen-free flame retardancy, low smoke emission, and harmlessness (low toxicity and irritation). Flexibility: XLPO has excellent flexibility and excellent stability within 160°C. Application range: Due to the good flame retardancy and flexibility of XLPO, it is often used in places with high temperature requirements (such as T4) and large bends in the harness. 2. Application differences Temperature grade: XLPE is suitable for occasions with relatively low temperature grades, such as T3 or T4 (but more inclined to T3), while XLPO is more suitable for occasions with higher temperature grades (such as T4). Flexibility requirements: XLPO has more advantages in places where higher flexibility is required (such as places where the harness is bendable). Flame retardancy requirements: In places where flame retardancy requirements are high, XLPO's halogen-free flame retardancy makes it more competitive. Cost: XLPE is relatively cheap, so if the cost is limited, XLPE may be a more suitable choice. XLPO may be relatively expensive due to its excellent flame retardancy and flexibility. Of course, the following is a summary description of the product comparison: XLPE and XLPO are both commonly used insulation materials in automotive cables, and they each have unique characteristics and advantages. When choosing, you should consider the specific application, temperature level, flexibility requirements, flame retardancy requirements, and cost.
