Problems solved by technology

[0004] The present invention provides a high-temperature-resistant and long-life cable and a preparation method thereof, which can effectively solve the problems in the above-mentioned background technology that the external protective shell of the cable currently used in electric power engineering is relatively soft, has weak protection ability for the cable wire, and is heat-resistant. The capacity is not ideal. When the temperature is high, the cable becomes soft seriously, which affects the service life of the cable and reduces the safety of the cable.

Abstract

The invention discloses a high-temperature-resistant and long-life cable and a preparation method thereof. The inner end surface of the outer protective shell is uniformly bonded with a support soft rod, and the inner side of the support soft rod is provided with an arc-shaped fixing groove. The inside of the shaped fixing groove is filled with polyimide filler, the two ends of the outer protective shell are symmetrically provided with embedded grooves, the inner of the embedded groove is embedded with a pulling wire, and the inner of the outer protective shell is wrapped with an inner protection shell, the present invention sets an outer protective shell, a supporting soft rod, an arc-shaped fixing groove and polyimide filling materials. The polyimide filling material inside the groove is not easy to deform in high temperature environment, supports the outer protective shell, and can withstand low temperature at the same time, the outer protective shell outside the cable is not easy to become soft and hard and cause rupture, prolonging the service life of the cable, and is safe High performance.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-temperature-resistant and long-life cable and a preparation method thereof. Background technique [0002] A cable is an electrical energy or signal transmission device, usually made of one or more mutually insulated conductors and an outer insulating layer, and a wire that transmits power or information from one place to another, usually consisting of several Or a rope-like cable made of several groups of wires twisted, each group of wires is insulated from each other, and is often twisted around a center, the entire outside is covered with a highly insulating covering, the cable has internal energization, external insulation Features, widely used in power engineering for the transmission of electrical energy; [0003] However, the quality of the outer protective shell of the cables used in power engineering is relatively soft, the protection ability for the cable conducto...
