1. 材质选择：PE线通常采用聚乙烯(Polyethylene)材料制成，具有良好的耐候性、耐腐蚀性和绝缘性能。在选择材料时应考虑其机械强度、抗冲击性和耐化学物质侵蚀能力。

1. Material selection: PE wires are usually made of polyethylene material, which has good weather resistance, corrosion resistance, and insulation performance. When selecting materials, consideration should be given to their mechanical strength, impact resistance, and resistance to chemical erosion.

尺寸规格：根据实际需要的电缆数量和尺寸，选择适当的PE线直径和壁厚。一般情况下，PE线直径的选择应满足电缆通过的要求，并留有适当的余量以方便安装和维护。

Size specifications: Select the appropriate PE wire diameter and wall thickness based on the actual number and size of cables needed. In general, the selection of PE wire diameter should meet the requirements for cable passage and leave appropriate margin for easy installation and maintenance.

3. 耐热性能：PE线在高温条件下应具备较高的热变形温度和长期使用温度，以保证其在工作环境中不会变形。通常要求PE线具有较高的耐热性能，能够承受高温环境的影响。

3. Heat resistance: PE wires should have high thermal deformation temperature and long-term use temperature under high temperature conditions to ensure that they will not deform in the working environment. PE wires are usually required to have high heat resistance and be able to withstand the effects of high temperature environments.

4. 阻燃性能：为确保，PE线应具备良好的阻燃性能，能够在火灾发生时自我熄灭，减少火势蔓延的风险。

4. Flame retardant performance: To ensure safety, PE wires should have good flame retardant performance and be able to self extinguish in the event of a fire, reducing the risk of fire spread.

5. 耐候性能：PE线一定具备较好的耐候性能，能够抵抗阳光、雨水、风沙等自然环境因素的侵蚀。耐候性能的好坏直接影响到PE线的使用寿命和性能稳定性。

5. Weather resistance: PE wires must have good weather resistance and can resist the erosion of natural environmental factors such as sunlight, rain, and sand. The weather resistance directly affects the service life and performance stability of PE wires.

6. 绝缘性能：PE线作为电缆保护管道，应具备良好的绝缘性能，能够在一定程度上隔离电缆与外界环境，防止漏电和电磁干扰。

6. Insulation performance: As a cable protection pipeline, PE wire should have good insulation performance, which can isolate the cable from the external environment to a certain extent, prevent leakage and electromagnetic interference.

7. 抗压能力：PE线需要具备一定的抗压能力，能够承受外部荷载和压力，防止因压力导致的形变和损坏。

7. Compression resistance: PE wires need to have a certain degree of compression resistance, be able to withstand external loads and pressures, and prevent deformation and damage caused by pressure.
