Description

Bare conductor insulation cladding structure

Technical Field

The utility model relates to a wire insulation technical field especially relates to an insulating cladding structure of bare conductor.

Background

In order to improve the power supply safety and reduce the fault rate, the national development reform committee issues guidance suggestions about accelerating the construction and the reconstruction of the power distribution network, and requirements on improving the equipment level of the power distribution network in the suggestions clearly indicate that the low-voltage line insulation is realized. However, since all the conventional low-voltage overhead line conductors are bare conductors, insulation modification of the bare conductors is required. At present, the insulation transformation of low-voltage overhead line conductors mainly has two modes: the bare conductor is replaced by the insulated conductor, and because the distance between the overhead bare conductor and the insulated conductor is long, the investment and reconstruction cost for directly replacing the insulated conductor is huge, a great amount of bare conductors within the service life are scrapped, and the waste is serious; and secondly, insulating the bare conductor on site, and the currently adopted method is to coat insulating paint, so that the modification cost is even higher than that of replacing the insulated conductor, and the comprehensive popularization condition is not met.

Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Referring to fig. 1, the present invention relates to a bare conductor insulation cladding structure, which includes an insulation layer 1, a fiber layer 2 for reinforcing structural strength, and a bonding layer 3 for bonding the bare conductor and the fiber layer 2, wherein the bonding layer 3 is coated on the outer surface of the bare conductor, the fiber layer 2 is coated on the outer surface of the bonding layer 3, the insulation layer 1 is coated on the outer surface of the fiber layer 2, and the thickness of the insulation layer is 1-3 mm.

Insulating cladding structure of bare conductor based on above-mentioned technical characteristics through setting gradually tie coat 3, fibrous layer 2 and insulating layer 1, directly covers tie coat 3 on bare conductor's surface with the gluing during the use, and insulating effect can be realized to insulating layer 1, and the construction is simple and convenient, and is with low costs. Meanwhile, the fiber layer 2 arranged in the middle can enhance the structural strength and ensure the insulation effect. The utility model discloses simple structure, excellent in use effect easily uses widely.

In this embodiment, the material of the bonding layer 3 is an RTV coating, and the RTV coating is a short-term Room Temperature vulcanized Silicone Rubber (Room Temperature Silicone Rubber) long-acting anti-pollution flashover coating, and has the advantages of excellent electrical performance and mechanical property, strong hydrophobicity and hydrophobicity migration, strong adhesive force, long service life, no need of blending during use, direct spraying after opening of a sealed package, curing to form a film after contacting with water molecules in the air, quality assurance, and simple construction, so the bonding layer 3 is very suitable for setting the cost. The thickness of the bonding layer 3 is 0.5-1.5 mm, and the specific thickness can be determined according to actual conditions. Generally, however, it is preferred that the adhesive layer 3 has a thickness of 1 mm.

It should be noted that, because the material of the bonding 3 layers is the RTV coating, in order to avoid the curing of the RTV coating, the bare conductor insulation coating structure should be put into a vacuum bag after being manufactured, and is vacuumized and sealed, and it is only required to be taken out when in use.

In this embodiment, the fiber layer 2 is made of a carbon fiber mesh, and the fiber layer 2 and the insulating layer 1 have the same size and are bonded by glue.
