产品特点

特点关键词∶物理性能好、高韧性、耐腐蚀、施工方便、耐冲击、密封性好、抗裂

1、优异的物理性能∶既具有良好的刚性、强度，也有很好的柔性。

2、耐腐蚀，使用寿命长∶PE电力电缆护套管具有很强的耐腐蚀性，聚乙烯为惰性材料，可耐酸碱腐蚀、其本身就是极好的防腐材料，一般的土壤、酸碱等因素都不会使管材腐蚀损坏，使用寿命一般为50年。

3、较好韧性和挠曲性∶高韧性管材，其断裂伸长率达到350%以上，对基础不均匀沉降和错位的适应能力强，抗震性好，小口径管材可任意弯曲。

4、连接方便，施工简单，方法多样。管材重量轻，只有钢管的1/7，是玻璃钢管的1/2，寿命却是钢管的4～5倍，运输、安装便捷，能大大降低工人的劳动强度，提高工作效率。焊接容易，焊接口少。管壁光滑，摩擦系数小，穿缆容易，施工工期效率高。

5、强度大、耐冲击，机械性能优越。管材使用的PE树脂，抗老化性能好，不易脆化，有韧性，能吸收冲击能，安装时受地形沉降影响小。

6、密封性好∶PE电力电缆护套管本身采用熔接连接，本质上保证了接口材质结构与管体本身的同一性，实现了接头与管材的一体化。其接口的抗拉强度与爆破强度均高于管材本体，可有效抵抗内压力产生的环向应力和轴应力。因此，与橡胶圈类接头或其他机械接头相比，不相存在接头扭曲造成的泄露危险，密封性能十分良好。

7、抗应力裂性好∶具有低的缺口敏感性，高抗剪切强度及优异的抗痕能力，耐环境应力性非常突出。

8、低温抗冲击性好∶聚乙烯的低温脆化温度极低，可在-20～40℃温度范围内安全使用。冬季施工时，因材料抗冲击性好，不会发生管子脆裂。

9、多种全新的施工方式∶PE管道具有多种施工技术，除了可以采用传统的开挖方式进行施工外，还可以采用多种全新的非开挖技术如顶管、定向钻孔、衬管、裂管等方式进行施工，这对于一些不允许开挖的场所，是唯一的选择，因此电力电缆护套应用领域更广泛。

运输包装

（一）注意事项∶

1、聚乙烯管相对轻和柔韧，易被尖锐物和石块等划伤。而表面是运行中产生开裂的诱因。

2、长时间的剧烈的日晒将加速管材的老化，缩短使用寿命。

3、油类、酸、碱、盐，尤其是活性剂类有机化学物质（不能使用的有酸雾、王水、浓度在98%以上的酸、碱、盐），附在管材上将使其运行中在一定条件耐环境应力裂的性能有所降低。

4、聚乙烯管的刚度相对较低，重压支撑不均等均易造成永久变形，影响使用寿命，甚至造成报废。（二）运输

1、管材在运输，装卸或搬运时要小心轻放，不得受到剧烈撞击，不得抛、摔、滚动及烈日曝晒，缆绳与管材接触处宜有软质材料隔离保护，装运时严禁管材放在管件上。

2、管材贮存地应平整，堆放整齐，堆放高度不超过2m，距离热源不少于5m。不得露天曝晒，如露天堆放应加以遮盖。

（三）安装

1、管沟的开挖必须严格按照设计图纸或工程监理指导的开挖路线及开挖深度进行施工，而且在没有征得相关部门同意的情况下不得擅自进行改动。

2、PE管道的柔性好、重量轻，所以采用热熔对接的管材可以在地面上预制较长管线，当地形条件允许时，管线的地面焊接可使管沟的开挖宽度减小。狭窄管沟的开挖可以采用旋转开挖机、犁或铲具等开挖机具。

3、管道铺设应在沟底标高和管道基础质量检查合格后进行，在铺设管道前要对管材、管件等重新作一次外观检查，发现有问题的管材、管件均不得采用。管道不得铺设在冻土上。管材连接好后平稳入沟槽内。管材在吊动及放入沟内时，应采用可靠的软带吊具，平稳下沟，不与沟壁或沟底激烈碰撞应防止划伤、扭曲或过大的拉伸和弯曲。聚乙烯管道宜蛇形敷设，并可随地形弯曲敷设。

4、放缆时为避免发生缠绕，应采用放缆机放缆。牵引纲缆与直埋管的连接可使用较粗的铁丝纵向穿过轴心，与光（电）缆相连。

Features

Feature keywords: good physical properties, high toughness, corrosion resistance, convenient construction, impact resistance, good sealing, crack resistance

1. Excellent physical properties: not only has good rigidity, strength, but also good flexibility.

2. Corrosion resistance and long service life: PE power cable sheath has strong corrosion resistance. Polyethylene is an inert material and can resist acid and alkali corrosion. It is itself an excellent anti-corrosion material, ordinary soil, acid and alkali. Such factors will not cause corrosion and damage to the pipe, and the service life is generally 50 years.

3. Better toughness and flexibility: high-toughness pipes, with a breaking elongation of over 350%, strong adaptability to uneven settlement and dislocation of the foundation, good seismic resistance, and small-diameter pipes can be bent arbitrarily.

4. Convenient connection, simple construction and various methods. The weight of the pipe is light, only 1/7 of the steel pipe, which is 1/2 of the glass steel pipe, but the life span is 4 to 5 times that of the steel pipe. The transportation and installation are convenient, which can greatly reduce the labor intensity of workers and improve work efficiency. Welding is easy and there are few welding ports. The pipe wall is smooth, the friction coefficient is small, the cable is easily threaded, and the construction period is efficient.

5. High strength, impact resistance and superior mechanical properties. The PE resin used in the pipe has good anti-aging performance, is not easy to be brittle, has toughness, can absorb impact energy, and is less affected by terrain settlement during installation.

6. Good airtightness: The PE power cable sheath itself adopts welding connection, which essentially ensures the identity of the interface material structure and the pipe body itself, and realizes the integration of the joint and the pipe. The tensile strength and blasting strength of the interface are higher than the pipe body, which can effectively resist the hoop stress and axial stress generated by the internal pressure. Therefore, compared with rubber ring type joints or other mechanical joints, there is no risk of leakage caused by joint distortion, and the sealing performance is very good.

7. Good stress crack resistance: low notch sensitivity, high shear strength and excellent trace resistance, and outstanding environmental stress resistance.

8. Good low-temperature impact resistance: The low-temperature embrittlement temperature of polyethylene is extremely low, and it can be used safely in the temperature range of -20 to 40°C. During construction in winter, because the material has good impact resistance, the pipe will not be brittle.

9. A variety of new construction methods: PE pipelines have a variety of construction technologies. In addition to traditional excavation methods, a variety of new non-excavation technologies such as pipe jacking, directional drilling, and liner can also be used. It is the only choice for some places where excavation is not allowed. Therefore, the application field of power cable sheath is more extensive.

It has a strong applicable type, which is suitable for the wearing of cables, wires and many other cables.

transport package

(1) Matters needing attention:

1. Polyethylene pipes are relatively light and flexible, and are easily scratched by sharp objects and stones. The surface is the cause of cracking during operation.

2. Long-term intense sunlight will accelerate the aging of the pipe and shorten the service life.

3. Oils, acids, alkalis, salts, especially active agent organic chemicals (acid mist, aqua regia, acids, alkalis, and salts with a concentration of more than 98%), attached to the pipe will make it The performance of resistance to environmental stress cracking under certain conditions is reduced during operation.

4. The rigidity of the polyethylene pipe is relatively low, and the uneven support of heavy pressure can easily cause permanent deformation, affect the service life, and even cause scrap. (2) Transportation

1. Pipes should be handled with care during transportation, loading and unloading or handling, and should not be subject to violent impacts, throwing, falling, rolling and exposure to hot sun. The contact between the cable and the pipes should be protected by soft materials. It is strictly forbidden to put the pipes in the pipe fittings during shipment. superior.

2. The pipe storage place should be level and neatly stacked, the stacking height should not exceed 2m, and the distance from the heat source should not be less than 5m. Do not expose to the sun, and cover them if they are stacked in the open air.

(Three) installation

1. The excavation of the pipe trench must be carried out in strict accordance with the design drawings or the excavation route and the excavation depth guided by the engineering supervision, and shall not be modified without the consent of the relevant department.

2. PE pipes are flexible and light in weight, so long pipelines can be prefabricated on the ground using hot-melt butt pipes. When local conditions permit, the ground welding of the pipelines can reduce the excavation width of the pipe trench. Excavation of narrow pipe trenches can use excavating tools such as rotary excavators, plows or shovel tools.

3. Pipeline laying should be carried out after the ditch bottom elevation and the quality of the pipeline foundation are qualified. Before laying the pipeline, perform a visual inspection of the pipes and fittings. Any pipes and fittings found to be problematic shall not be used. The pipeline must not be laid on frozen ground. After the pipe is connected, it enters the groove smoothly. When the pipe is hoisted and put into the ditch, a reliable soft belt sling should be used to go down the ditch steadily and avoid violent collision with the ditch wall or the ditch bottom. It should be prevented from being scratched, twisted, or excessively stretched and bent. Polyethylene pipes should be laid in a serpentine shape, and can be bent along with the terrain.

4. In order to avoid entanglement when unwinding the cable, the unwinding machine should be used to unwind the cable. The connection between the traction cable and the direct buried pipe can use a thicker iron wire to pass through the axis longitudinally and connect with the optical (electric) cable.
