A vulcanization-free rubber insulated cable

Abstract

The invention discloses a vulcanization-free rubber insulated cable, which includes a support, a cable group, a protective layer, and a buffer layer. The cable group includes several twisted cables, and the outer surface of the cables is from the inside to the outside. Wrapped with an insulating layer and a heat insulating layer in sequence, the protective layer includes a shielding layer, a vulcanization-free rubber layer and a self-repairing layer arranged sequentially from the inside to the outside; the self-repairing layer is made of the following components in parts by mass: 5‑10 parts of carbon nanotubes, 5‑10 parts of graphene, 10‑15 parts of urea, 15‑20 parts of formaldehyde, 5‑10 parts of polyurethane, 4‑8 parts of azobisisoheptanonitrile, 6‑parts of dicyclopentadiene 12 parts, OP-10 6-8 parts, epoxy resin 10-15 parts, triethanolamine 2-4 parts and distilled water 20-30 parts. The invention is coated with a self-repairing layer, prolongs the service life of the cable, improves the safety of the cable, reduces detection and maintenance costs, and enhances the tear resistance and corrosion resistance of the cable.

Description

technical field [0001] The invention relates to the technical field of cable production, in particular to a vulcanization-free rubber insulated cable. Background technique [0002] With the continuous development of science and technology, the demand for electric power continues to increase. As the most basic tool for electric transmission, the quality requirements of cables are also particularly important. The traditional vulcanization-free rubber insulated cable has poor wear resistance and impact resistance, and lacks self-repair ability. After long-term use or external mechanical movement, it is very easy to cause damage and fracture and shorten its service life. At the same time, it will cause safety problems. Thus affecting the safe and normal operation of the power grid. However, in order to ensure the normal supply and demand of electricity, manual monitoring is required all the time. If a fault occurs, the old cable must be replaced in time. However, the user's ele...

The traditional vulcanization-free rubber insulated cable has poor wear resistance and impact resistance, and lacks self-repair ability. After long-term use or external mechanical movement, it is very easy to cause damage and fracture and shorten its service life. At the same time, it will cause safety problems. Thus affecting the safe and normal operation of the power grid

However, in order to ensure the normal supply and demand of electricity, manual monitoring is required at all times. If a fault occurs, the old cable needs to be replaced in time. However, the long time for detection and replacement often delays the user's power consumption, and the cost of detection and maintenance is high.
