穿线用热浸塑穿线管随着电力工作、信息产业和国民经济的不断发展，环境保护问题逐步引起人们的注重，线缆入地在城市电网建造、通讯管道建造和改造中得到大规模推行。穿线用热浸塑穿线管是引入国外的技能和工艺研制生产的一种新式绿色环保管道，并取得电力工业电气设备质量检验测试中心签发的检测报告证书，产品符合G2电气装置用导管的技能要求，通用要求规范。表里防腐层可运用FPE聚乙烯粉末、环氧树脂粉末，经特殊工艺运用塑料层与钢管层表里壁高温熔结，与钢管有的结合力，涂层外表润滑、漂亮。

电缆涂塑套管是以焊接钢管或无缝钢管为基体，通过分外技术在内壁熔融喷涂或吸附食品级环氧粉末涂料或PE资料经高温固化而成的新式复合资料。为表里涂敷聚乙烯或改性环氧树脂粉末的钢塑复合管道。具有的耐化学安稳性和耐腐蚀性，机械功用好、抗压强度高，可以对电缆起到十分好的保护作用。

热浸塑电力钢管具有以下特色:1、强度高；2、绝缘无电腐蚀；3、阻燃，耐热功用好；4、内壁润滑，不刮伤电缆；5、承插式衔接，便利施工；6、重量轻，装置施工简捷便利，两人便可就地实施装置；7、运用范围广：适用电缆埋地敷设时作维护管用，也运用于电缆过桥过河等高要求场合。
Characteristics of plastic coated steel tubes for power cable threading; ( 1 ) high pressure bearing and excellent mechanical function of steel tubes. youcheng plastic-coated composite steel tube has the advantages of continuous steel tubes. it has high mechanical strength, strong ability to accept external impacts such as impacts, twists and turns, can accept harsh application conditions and is high in safety. ( 2 ) excellent chemical corrosion resistance and good anti-corrosion effect of the whole system. youcheng plastic-coated composite steel pipe has two strengths of steel pipe and plastic pipe, and plastic coating has strong acid and alkali resistance, soil corrosion resistance and weather resistance, which is suitable for transporting fluids containing sulfur, calcium, magnesium and other corrosive media in coal mines. The products can be coated with flanges, and all kinds of pipe fittings of tee and bend number one are subjected to exterior-interior plastic coating and anticorrosion treatment to ensure the anticorrosion effect of all pipelines, and the service life can be several times as long as that of ordinary steel tubes. ( 3 ) the coating adhesive force is strong, and youcheng plastic-coated composite steel pipe adopts physical deep treatment process, and the pretreatment reaches sa 2.5 specification, with anchor grain depth between 50 and 65; Grafting modified antistatic powder coating or adding polar groups, microcomputer full-automatic preheating control and automatic production are adopted, scientific and reasonable process and advanced equipment ensure the coating quality, and its adhesive force is obviously higher than national standard. ( 4 ) no nodulation, no scaling and little fluid resistance. the inner and outer coating of youcheng exterior-interior coated plastic composite steel tube is fine, with self-lubricating property, no nodulation and scaling. the wear resistance coefficient and roughness coefficient are less than those of ordinary steel tubes. the circulation capacity of the same pipe diameter can be increased by 15 - 30 %, the transportation power can be saved by 15 %, which is attributed to products with high economic, environmental protection and cost performance. ( 5 ): flame retardant and antistatic, the product is made of special mineral polyethylene powder coating, and its antistatic and flame retardant components are evenly distributed on the outer surface and inner layer of the pipe, which meets the requirements of mt 181 rule and is suitable for inflammable and explosive special places under the mine. In these circumstances, cable sleeves must be paid special attention to, and only by paying attention to good quality can they have good sales volume. The advantages of laying cable sleeves are that they are less influenced by external forces, occupy less land, can bear large loads, and cable laying has no mutual influence. After the construction of the civil part of the cable sleeve, the cable can be cast easily. Its disadvantages are: the pipeline construction cost is high, and it is not suitable for bending; thermal expansion and contraction of cables will lead to fatigue of metal sheaths, poor heat dissipation conditions of cables, and it is difficult to replace cables. The hot dip plastic cable threading protection tube has a very high sales volume, which is not only a comprehensive result of data, but also can be seen from its application range, such as civil circulating water, industrial circulating water, fire water supply, building drainage, chemical fluid transportation, mine drainage and so on, all of which need its assistance.
