Abstract

The invention discloses an ethylene propylene rubber insulated salt-spray-resistant rubber jacketed flexible cable, and particularly relates to the technical field of wires and cables. The cable comprises a cable body, the inner layer of the cable body comprises four conductors, the conductors are coated with insulating layers, the four insulating layers are coated with a circle of flame-retardant wrapping tape layer, and a sheath layer is coated outside the flame-retardant wrapping tape layer. The miniature electric push rod pushes the two stranding pressing plates to be close to each other, the stranding pressing pads press and tighten a plurality of stranded wires entering the stranding cavity, the possibility of loosening of the stranded wires during stranding is reduced, the quality of conductors during stranding is improved, the driving motor drives the gear to be meshed with the outer gear ring, The plurality of stranded wires in the stranding seat can be stranded, a single conductor is formed after the plurality of stranded wires are stranded, the number of stranding processing procedures is small, the forming efficiency is high, the plurality of stranded wires can be tensioned through the arrangement of the hydraulic rod, and the stranding quality is improved.

Description

technical field [0001] The invention relates to the technical field of electric wires and cables, in particular to an ethylene-propylene rubber insulated and anti-salt spray rubber-sheathed flexible cable. Background technique [0002] Cable is a kind of electric energy or signal transmission device, which is usually composed of several wires or groups of wires. In the process of urban construction, it is the minimum construction requirement for cables to go into the ground. In the process of urban reconstruction, cables are mostly erected in the air or installed Underground and underwater, it is used for telecommunications or power transmission; in order to ensure the normal and stable operation of the cable, the cable must have basic safety performance, such as wear resistance, flame retardancy, fire resistance, etc. It has corresponding characteristic properties, such as insect repellency, anti-corrosion, cold resistance, etc. At present, the common cables realize the moi...
