A flame-retardant, heat-resistant, high-temperature-resistant, and highly elastic control cable

Abstract

The invention discloses an inflaming retarding, heat resisting, high temperature resisting and high elasticity controlling cable which comprises a main controlling conductor and an auxiliary controlling conductor. The main controlling conductor is bent around the auxiliary controlling conductor, the two ends of the main controlling conductor abut against the auxiliary controlling conductor, an elastic extruded bar is arranged between the main controlling conductor and the auxiliary controlling conductor, the main controlling conductor and the auxiliary controlling conductor are sequentially wrapped with a fireproof mica tape tapped covering, a tinned copper wire braided shielding layer and a polyvinyl chloride outer jacket layer, and gaps between every two of the main controlling conductor, the auxiliary controlling conductor and the fireproof mica tape tapped covering are filled with high temperature resisting material padding strips. The inflaming retarding, heat resisting, high temperature resisting and high elasticity controlling cable has the advantages of inflaming retarding, heat resistance, high temperature resistance, high elasticity and the like, the requirements for normal operation of the cable in a severe environment are met, discharge damage between cable cores and between cables is prevented, influences of the unsatisfactory shielding effect on operation of the cable are avoided, and the service life of the controlling cable is prolonged.

Description

technical field [0001] The invention relates to the technical field of control cables, in particular to a flame-retardant, heat-resistant, high-temperature-resistant and highly elastic control 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, industries such as 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 cable, but also to use it under high temperature conditions, that is, high temperature resistance. Especially for control cables used in environments such as anti-corrosion and high temperature resistance, and need to be able to prevent discharge damage between cable cores and between cables, and have high mechanical properties such as high tensile strength, elongation a...

Problems solved by technology

In addition, the shielding effect of ordinary fire-resistant control cables is not ideal, and the outer sheath is easily damaged, which will affect the operation of the entire cable during actual use.
