Embodiment 1

[0020] An overhead insulated cable, comprising the following raw materials in parts by weight: 30 parts of polyolefin resin, 1 part of ferrite nanoparticles, 8 parts of carbon black, 1 part of light stabilizer, 0.5 part of antioxidant, 1 part of acrylic fiber, solvent 20 parts, 10 parts of filler.

Embodiment 2

[0022] An overhead insulated cable, comprising the following raw materials in parts by weight: 50 parts of polyolefin resin, 3 parts of ferrite nanoparticles, 12 parts of carbon black, 3 parts of light stabilizer, 1 part of antioxidant, 3 parts of acrylic fiber, solvent 30 parts, 40 parts of filler.

Embodiment 3

[0024] An overhead insulated cable, comprising the following raw materials in parts by weight: 40 parts of polyolefin resin, 2 parts of ferrite nanoparticles, 10 parts of carbon black, 2 parts of light stabilizer, 0.8 part of antioxidant, 2 parts of acrylic fiber, solvent 25 parts, 25 parts of filler.

[0025] Wherein, the antioxidant described in the above-mentioned Examples 1 to 3 is formed by mixing dihydroquinoline and amine phosphate according to a mass percentage of 1:2. The solvent is formed by mixing cyclohexane, toluene, n-octane, dimethyl carbonate and diethyl carbonate according to the mass percentage of 1:1.2:1:1.3:1.2. The light stabilizer is benzophenone or benzotripyridine. The filler is selected from one or more of talcum powder, calcium carbonate, aluminum hydroxide, silica lime, magnesium hydroxide, glass fiber, calcium silicate, mica, and potassium titanate.

[0026] The preparation method of the overhead insulated cables described in Examples 1 to 3 above...

Abstract

An overhead insulated cable comprises the following raw material in parts by weight: 30-50 parts of polyolefin resin, 1-3 parts of ferrite nanoparticles, 8-12 parts of carbon black, 1-3 parts of a light stabilizer, 0.5-1 part of an antioxidant, 1-3 parts of acrylic fibers, 20-30 parts of a solvent and 10-40 parts of a filler. The overhead insulated cable has the following beneficial effects: the overhead insulated cable has strong sunscreen ability and is not easy to age under long-term irradiation of ultraviolet rays; and meanwhile, the good telescopic performance and tensile strength are achieved.

Description

technical field [0001] The invention belongs to the field of cables, and in particular relates to an overhead insulated cable. Background technique [0002] The cable is usually a rope-like cable twisted by several or groups of wires [at least two in each group]. Each group of wires is insulated from each other and is often twisted around a center. Insulating covering. Most of them are erected in the air or installed underground or underwater for telecommunications or power transmission. [0003] Cables and wires are generally composed of three components: core wire, insulating sheath and protective sheath. [0004] Overhead cable (full name overhead insulated cable) is an overhead wire equipped with an insulation layer and a protective sheath. It is a special cable manufactured by a production process similar to cross-linked cables. It is a new power transmission between overhead wires and underground cables. Way. Aerial cables are all single-core, which can be divided ...
