Description

technical field [0001] The invention relates to the technical field of power cable protection tubes, in particular to a novel breakdown-resistant power cable protection tube. Background technique [0002] The power cable is the carrier of power transmission and information transmission. The protective tube material is an indispensable outer structure part of the power cable, which plays a role in protecting the cable, ensuring smooth transmission of electrical / optical signals in the cable, and making the wire and cable The conductive alloy / optical fiber inside is isolated from water, air and other media to avoid damage, interference with external substances, or loss of transmission function, and prevent transmission performance from deteriorating. With the strengthening of people's awareness of environmental protection, many countries in the world have banned harmful components such as lead and cadmium in protective tube materials, and with the progress of society and the ra...
