Abstract

The invention belongs to the technical field of insulating material preparation, and discloses an insulating adhesive tape. The insulating adhesive tape comprises an insulating adhesive tape body andanti-sticking layers arranged on the upper and lower surfaces of the insulating adhesive tape body, wherein the insulating adhesive tape body has a thickness of 0.8-2.3 mm, and the anti-sticking layerhas a thickness of 0.1-0.2 mm, and the insulating adhesive tape body is a polyvinyl chloride film. According to the insulating adhesive tape provided by the invention, the anti-sticking layers are arranged on the surfaces of the insulating adhesive tape body, so that the problem of interlayer adhesion of a wound insulating adhesive tape is solved.

Description

technical field [0001] The invention belongs to the technical field of insulating material manufacture, and in particular relates to an insulating adhesive tape. Background technique [0002] At present, one of the ways to solve the phase-to-phase short circuit problem caused by the climbing of small animals in the dry-type air-core reactor star frame is to set an insulating layer on the surface of the dry-type air-core reactor star frame. The insulating tape is convenient and quick for construction. It is widely used because of its high insulation performance. The thickness of the existing insulating tape is generally 0.3-1.0mm, and it is wound into a roll every 30-100m, but in the actual use process, it is found that the wound insulating tape will start to stick in about 3-7 days, resulting in the use of While inconvenient, it also affects the insulation performance and construction performance of the insulating tape, and in serious cases, it will even all stick together ...
