Heat resistant elastic cable

Abstract

The invention discloses a heat resistant elastic cable. The cable comprises a protective sleeve, the outer wall of the protective sleeve is provided with a cable marking line, the inner wall of the protective sleeve fits a temperature-resistant elastic layer, the inner wall of the temperature-resistant protective sleeve is wrapped with a wire layer, the inner wall of the wire layer wraps a wire, the temperature resistant elastic layer comprises insulating shield, the inner wall of the insulating shield is wrapped with a tape, the inner wall of the tape is laminated with a tensile aramid layer,the inner wall of the tape is wrapped with an insulating layer, the inner wall of the insulating layer wraps a core, and a wire outer wall fits a main line. The cable has the advantages of high oxygen index, good flame retardancy, oil resistance, chemical corrosion resistance, tear resistance, low temperature flexibility, strong elasticity and good stress buffering through the arrangement of theprotective sleeve, the cable marking line and the heat resistant elastic layer, the requirements for normal operation of the cable in harsh environments are met, discharge damage between the cable core and the cable is prevented, the service life of a control cable is prolonged, and a product streamlined appearance structure is exquisite.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a heat-resistant elastic cable. Background technique [0002] With the rapid development of the national economy, the amount and scope of use of wire and cable are increasing. In recent years, power plants, substations, smelting and petrochemical industries have a great demand for control cables. In use, it is necessary not only to avoid mechanical damage, insulation damage, insulation aging and deterioration of the control cables, but also to protect them under high temperature conditions. It is used under the environment, that is, high temperature resistance, especially for control cables used in anti-corrosion, high temperature and other environments, and it is necessary to prevent discharge damage between cable cores and between cables, and have high tensile strength and fracture resistance. Mechanical properties such as elongation, as well as high and low temperature resista...
