pvc穿线管价格多少钱一米

 pvc穿线管的价格和它的性能也有关系。培达塑料生产的pvc穿线管性能特点有:
 
1、套管的内外壁光滑,摩擦系数小。可减少电线、电缆在管道内的阻力。
 
2、抗压性能高,可以明装也可暗敷于混凝土内,不会受压破坏,中型和重型管系列适合暗敷在混凝土中。
 
3、抗冲击、耐热性能好,套管在混凝土浇注过程中,能承受正常的捣固冲击而不破裂,且在混凝土凝结作用下,不会软化变形。
 
4、套管防潮耐酸碱性能优良,不会锈蚀,且耐酸、耐碱、耐油。各连接处按规定用PVC粘合剂粘接,可防水渗进管内,防潮效果更佳。因而适合在腐蚀性环境中使用。
 
5、阻燃性能好,具有难燃性,不易燃烧的特点。离火自熄,火焰不会沿着管道蔓延。
 
6、套管有优良的绝缘性能,抗电流击穿电压高,无带电危险。可有效的防止意外漏、触电事故。
 
7、防虫鼠,套管不会发出虫鼠喜欢的气味,可避免虫鼠啃咬破坏。
 
8、套管韧性好,易弯曲,套管内只须插入一根相应的专用弹簧,无需加热在常温下用手轻轻用力,即可进行随意弯曲成所需的角度。
 
9、适用性强,在冬季气温较低时仍可保证冷弯施工,不受季节影响。
 
10、施工方便,套管需要截断时,可用截管器轻便地截断。用PVC粘合剂可以快速而方便地将套管连接成施工所需形状的管道。
