为了实现上述目的，本发明是通过如下的技术方案来实现：其配方为PVCSG-3100g、增塑剂50g、环氧大豆油5g、氯化石蜡8g、氧化锑5g、抗氧剂0.5g、煅烧陶土5g、填料10g、稳定剂7g、光稳定剂3g、DOS30g和适量内外滑剂制作而成。 
作为优选，所述增塑剂为DOP和TOTM的混合物。 
作为优选，所述DOP占5%，所述TOMTM占10%。 
作为优选，所述阻燃剂为高性能阻燃剂。 
作为优选，所述增塑剂为TOTM。 
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。
