Embodiment Construction

[0011] Such as figure 1 As shown, it is an extra-soft non-twisting control cable, which includes a left and right two-way twisted cable core. The cable core includes four sets of cores 1, fillers 2 and PP wrapping tape 3, and PP wrapping tape 3 is wrapped in four Assemble the core 1 and the outer periphery of the filler 2. Each set of wire cores 1 is composed of a copper wire stranded conductor 1-1 and a cross-linked polyethylene insulating layer 1-2 extruded outside the conductor 1-1. The cable core is extruded and wrapped with a foamed polyethylene buffer layer 4, and the foamed polyethylene buffer layer 4 is wrapped with a tinned copper tape shielding layer 5, and the tinned copper tape shielding layer 5 is provided with seven copper wire drainage wires 6, tinned Copper tape shielding layer 5 is extruded and wrapped with outer sheath layer 7 .

Abstract

The invention provides a highly flexible non-twisting control cable, and belongs to the technical field of cables. The cable comprises a left and right bi-directionally twisted cable core; a foamed polyethylene buffer layer is externally extruded and covered on the cable core, a tin-plated copper band shielding layer wraps the foamed polyethylene buffer layer, and an external protection layer is externally extruded and covered on the tin-plated copper band shielding layer; the cable core comprises four groups of wire cores, filling materials and a PP lapping band, wherein the PP lapping band wraps the four groups of wire cores and the filling materials; and the cable core also comprises a conductor and a crosslinking polyethylene insulation layer externally extruded and covered on the conductor. The cable has the advantages of high electric performance, shielding performance, mechanical properties such as tensile property and twisting resistance, thermal resistance and ageing resistance, environmental resistance, chemical corrosion resistance and fire resistance, convenient use, no limitation of laying drop heights and the like; and the cable can be laid in fixed places, such as rooms, tunnels, cable trenches and tubes, where the shielding requirements are high, and the cable can be widely used and has better social and economic benefits.

Description

technical field [0001] The invention relates to an ultra-soft non-twisting control cable structure, which belongs to the technical field of cables. Background technique [0002] At present, with the rapid development of my country's industry, the degree of electrical automation is widely used in various industries. Traditional cables basically use a twisting direction when they are cabled—right direction. Since the cores of this kind of cable are all tightly twisted together, when the cable is working, the heat dissipation is not good, and the carrying capacity of the cable is reduced. Thus affecting the electrical conductivity and running quality of the cable. Contents of the invention [0003] In order to overcome the deficiencies of existing cables in terms of non-twisting, tensile and shielding properties, the present invention provides an extra-soft non-twisting control cable with good torsion resistance, corrosion resistance, aging resistance, good shielding perform...
