Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage insulation pads, in particular to a roll-type high-voltage insulation pad. Background Art

[0002] High-voltage insulating floor mats are widely used in substations, power plants, distribution rooms, laboratories and field live operations. They are mainly made of rubber insulating materials. There should be no harmful irregularities on the upper and lower surfaces of the insulating mats. Harmful irregularities refer to one of the following characteristics, that is, defects that destroy uniformity and damage the smooth contour of the surface, such as small holes, cracks, local ridges, incisions, inclusions of conductive foreign matter, folds, gaps, concave and convex corrugations and casting marks, etc. Harmless irregularities refer to surface irregularities formed during the production process.

[0003] When the high-voltage insulating pad is in use, it needs to be laid at the location where it is used. When the high-voltage insulating pad needs to be rolled up, it is mostly necessary to roll it up manually, which brings trouble to the rolling up of the high-voltage insulating pad and is inconvenient to automatically roll up the high-voltage insulating pad. Therefore, we propose a roll-type high-voltage insulating pad. Utility Model Content
