Embodiment Construction

[0035] The specific technical solutions of the present invention are described in conjunction with the accompanying drawings.

[0036] Such as figure 1 As shown, a water-blocking electrified railway anti-mildew, rodent and termite-proof cable, its structure includes: conductor 1, conductor water-blocking layer 2, conductor shielding layer 3, insulating layer 4, insulating non-metallic shielding Layer 5, insulating metal shielding layer 6, first water blocking layer 7, inner sheath layer 8, flame retardant wrapping layer 9, armor layer 10, second water blocking layer 11, outer sheath 12.

[0037] The conductor 1 is a stranded conductor in which a number of copper wires are regularly arranged according to the specified pitch and the adjacent layers are twisted in opposite directions; the bare copper wires have a single diameter of 2.86 mm, 37 pieces, and are concentrically adjacent to each other. The outer diameter of the layer is 28.6±0.05mm after tight-pressing and stranding ...

Abstract

The invention relates to a circular power cable for an oil-submerged pump and a preparation method of the cable, and belongs to the technical field of manufacture of cables for electrified railways ofrailway traffic equipment. The cable comprises a conductor, a conductor waterproofing layer, a conductor shielding layer, an insulating layer, an insulated non-metal shielding layer, an insulated metal shielding layer, a first waterproofing layer, an inner sheath layer, a flame-retardant wrapping layer, an armored layer, a second waterproofing layer and an oversheath successively from inside to outside. The provided cable has an excellent radial waterproof performance; the cable is resistant to moisture and prevented from mildew in the wet environment; the cable is characterized by resistantto mice and termites; the cable is convenient to install and operate due to the soft and tensile features; and the cable can meet the reality of continuously development of high-speed railway electrified equipment.

Description

technical field [0001] The invention belongs to the technical field of cable manufacturing for rail transit equipment electrified railways, in particular to a round power cable for submersible oil pumps and a preparation method thereof. Background technique [0002] With the rapid development of my country's electrified railway equipment technology, the requirements for wires and cables for electrified railway equipment are also increasing accordingly. Since cables in this field are generally laid underground or in cable trenches, the environment for cable laying is humid, and different There are a lot of rats and termites in the area, so the special laying environment requires that the ordinary cables currently in use cannot meet the actual needs. The anti-mildew, water-blocking characteristics, rodent-proof, termite-proof, softness and convenience of installation of cables are the trend of technological development in the industry; in order to pursue the development directi...
