Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0015] Such as figure 1 As shown, a reinforced polyvinyl chloride insulated control cable according to the present invention includes a conductor 3 twisted by oxygen-free copper wire bundle 1 and aramid fiber filament 2, and an insulating layer is arranged outside the conductor 3 4. A shielding layer 5 is provided on the outside of the insulating layer 4, and the conductor 3, the insulating layer 4 and the shielding layer 5 form a conductive unit. There is a reinforcing core 6, a filling layer 7 is arranged outside the conductive unit and the reinforcing core 6, a first wrapping layer 8 is arranged outside the filling layer 7, and a copper wrapping layer 8 is arranged outside the first wrapping layer 8. Wire braiding layer 9, a second wrapping layer 10 is arranged outside the copper wire braiding layer 9, an outer sheath layer 11 is arranged outside th...

Abstract
The invention relates to a reinforced polyvinyl chloride insulation control cable. The reinforced polyvinyl chloride insulation control cable comprises conductors, wherein each conductor is formed by twisting an oxygen-free copper harness and aramid fibers, an insulation layer is arranged outside each conductor, a shielding layer is arranged outside the insulation layer, the conductor, the insulation layer and the shielding layer form a conductive unit, the two conductive units are arranged, a reinforcement core is arranged at an external part where the two conductive units are tangential, a filling layer is arranged outside the conductive units and the reinforcement core, a first wrapping layer is arranged outside the filling layer, a copper wire weaving layer is arranged outside the first wrapping layer, a second wrapping layer is arranged outside the copper wire weaving layer, an outer sheath layer is arranged outside the second wrapping layer to form a cable body, and the diameter of each conductive unit accounts for one third of the diameter of the cable body. The reinforced polyvinyl chloride insulation control cable has good conductivity, is high in integral strength and long in service lifetime, is safe and reliable, and can continuously work for a long time.
Description
technical field [0001] The invention relates to a cable, in particular to a polyvinyl chloride insulated 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, there are various cables on the market, and they are used in various occasions. However, most cables have some problems, such as poor insulation effect, short service life, high manufacturing cost, and low overall strength. Contents of the invention [0004] Purpose of the invention: The purpose of the invention is to overcome the deficiencies in the prior art and provide a reinforced PVC insulated control cable with good electrical conductivity, high overall strength, continuous operation for a long time, safety and reliability, and long service life...
