下有电缆标志桩按材质分类
Cable marking piles below are classified according to material
1.水泥电缆桩：由于水泥电缆桩制作成本和运输成本高，已经逐渐被淘汰。
1. Cement cable pile: Because of the high production and transportation costs of cement cable pile, it has been gradually eliminated.
2.玻璃钢电缆桩：经高温挤压而成，具有抗冲击、耐磨损、耐高温、耐腐蚀等特性并且适合各种酸碱土壤，使用寿命长达30年以上。便于运输和安装，相比于水泥重量轻，无回收价值，自然防盗。
2. FRP cable pile: extruded at high temperature, it has the characteristics of impact resistance, wear resistance, high temperature resistance, corrosion resistance and is suitable for various acid-alkali soils. Its service life is more than 30 years. Easy to transport and install, lighter weight than cement, no recycling value, natural anti-theft.
3.pvc塑钢电缆桩：塑钢电缆桩是采用PVC聚氯乙烯生产而成的。本材质具有轻便、弹性好、耐酸碱耐腐蚀，抗老化性能好，安装和运输方便，重量轻等特点。
3. PVC plastic steel cable pile: plastic steel cable pile is made of PVC polyvinyl chloride. This material has the characteristics of light weight, good elasticity, acid and alkali resistance, corrosion resistance, good aging resistance, convenient installation and transportation, light weight and so on.
