[0004] At present, PVC (polyvinyl chloride) is generally used as the outer sheath of high-precision intelligent instrumentation cables. Although this kind of cable has good flexibility and is convenient for laying during construction, it is prone to adhesion and compression resistance at high temperatures. Weak and easy to crack when in contact with oil substances and affect the reasonable service life is its shortcoming
