针对现有技术上存在的不足，本发明目的是在于提供一种性能优良的散热性良好又节能的PVC电缆套管。 
为了实现上述目的，本发明是通过如下的技术方案来实现：其原料由70%-80%的聚氯乙烯树脂、5%-10%的稳定剂、3%-5%的润滑剂、3%-5%的填充剂、1%-2%的增色剂、1%-2%的抗压剂和1%-2%的其他材料制作而成； 
其制备方法：将上述原料经磨粉并在135-150℃拌料，机械均匀混合后，分别加入两台锥形双螺杆挤出机在180-210℃时共同挤出电缆护套 管。 
作为优选，所述稳定剂为有机锡类。 
作为优选，所述润滑剂为油酸。 
作为优选，所述填充剂为实心微珠。 
作为优选，所述抗压剂为苯乙烯共聚物，所述抗压剂还含有增塑剂。 
本发明产品具有耐高温和抗老化性能好，能适应电力电缆使用过程因过载短路而产生的高温，材料具有高绝缘强度和体积电阻率；柔性好且抗压强度大、抗不均匀沉降，在施工现场无须包封浇混凝土；内壁表面磨擦系数小，利于使用，产品寿命长。 
下面结合具体实施方式来详细说明本发明。
