Product characteristics of insulated type A ladder and precautions when using it
1. Overview of insulated ladders
The types of insulated ladders produced by our factory are: insulated single ladders, insulated combined ladders, insulated herringbone ladders, insulated telescopic single ladders, insulated lift combined ladders, insulated lift herringbone ladders.The company's insulating ladder is a ladder made of glass fiber reinforced plastic profiles pultruded with glass fiber and epoxy resin as the main materials.It has the advantages of high strength, corrosion resistance, beautiful appearance and good electrical properties.It can usually withstand the power frequency test voltage of “250kV/m”.Therefore, glass fiber reinforced plastic insulated ladders can be used as a climbing tool for power systems.
Second, the characteristics of insulated type A ladder
1．It is made of glass fiber reinforced plastic profiles that are pultruded with glass fiber and epoxy resin as the main materials.
2．The aluminum alloy parts have been anodized on the surface, and the shaft steel parts have a protective coating on the surface.
3．The surface of the parts made of insulating laminated materials is treated with insulating paint.
4．The non-slip design of ladder support and ladder feet is not easy to fatigue, the shape of each component of the ladder has no sharp edges and corners, the degree of ** is high, and the insulation performance is strong.
5．Low water absorption, corrosion resistance, suitable for live line operations; substation maintenance operations.
3. Insulation technical parameters
(1) The insulation type A ladder assembly is allowed to meet: 800N
(2) Insulated type A ladder power frequency withstand voltage: 250KV/1m, 1min
Fourth, precautions for the use of insulated type A ladder
1． Before use, it should be implemented in strict accordance with the GB17620-1998 standard. Before use, the operator should carefully check the main body and parts of the insulated ladder for defects or cracks.
2． Strictly abide by **operating procedures, put an end to luck, and ensure personal safety.
3． Prevent moisture and damage, so as not to affect the insulation level.
4． In order to ensure the reliability of product performance, the performance must be tested on an annual basis.
