Problems solved by technology

Due to its structural characteristics, the overall reliability of this control cable is not strong, and it does not have good strength.
In the event of a fire, ordinary control cables cannot guarantee that the line will continue to work
In addition, due to the copper core copper sheathed magnesium oxide insulated cables on the market, due to the drawing process and the use of magnesium oxide as cable insulation, the number of cable cores is limited, and its insulation reliability is also very poor.

Abstract

The invention relates to a multi-core control cable, which comprises a conductor, wherein an insulation layer is arranged outside the conductor, a filling layer is arranged outside the insulation layer, an inner jacket layer is arranged outside the filling layer, a steel-wire armored layer is arranged outside the inner jacket layer, copper wires are uniformly arranged inside the steel-wire armored layer, and an outer jacket layer is arranged outside the steel-wire armored layer. The multi-core control cable is high in strength, good in insulation flame retardant effect and strong in reliability.

Description

technical field [0001] The invention relates to a cable, in particular to a control cable. Background technique [0002] With the rapid development of the national economy, as the main artery of the national economy, the amount and scope of wire and cable are increasing. In recent years, power plants, substations, smelting and petrochemical industries have a great demand for cables. [0003] At present, ordinary control cables generally use polyvinyl chloride as insulation, and the sheath material is cross-linked polyvinyl chloride. Due to its structural characteristics, the overall reliability of this control cable is not strong, and at the same time, it does not have good strength. In the event of a fire, ordinary control cables cannot guarantee that the line will continue to work. In addition, due to the copper core copper sheathed magnesium oxide insulated cables on the market, due to the drawing process and the use of magnesium oxide as cable insulation, the number o...
