Insulation ladder characteristics

The insulating ladder series

Insulation ladder product classification: insulation, insulation ladder type A ladder, insulation, insulation ladder, eight ladder insulation telescopic ladder, insulating A type telescopic ladder, insulating ladder, insulation, insulation platform ladder step etc.. (can be customized according to customer demand!)

Electrical insulating ladder is the use of glass steel material processing with glass fiber and epoxy resin as the main material and pultrusion molding a ladder. It has the advantages of high strength, corrosion resistance, beautiful appearance and good electric properties. Usually the power frequency test voltage tolerance "250kV/m" can be. Thus the glass steel ladder can be used as a safe climbing tool for power system. To replace the metal ladder and bamboo ladder. To prevent the induction and anti misoperation caused by electric shock accidents. To undergo a rigorous test of glass steel can also be used with the ladder high-voltage live homework.

The main technical parameters of electrical insulation ladder

1, insulation material density ≥ 1.95g/cm3

2, insulation material of <0.40% water absorption rate

3, the tensile strength of >350Mpa

4, the surface hardness of 50 (Pap)

5, the surface of the insulation material of pressure >12kv (r.m.s)

The >880 load 6, design (bovine)

(a) appearance, assembly

The 1 concept: ladder shape must not have sharp edges and corners of each component, should be inverted arc.

The 2 assembly: shall conform to the provisions of the YB3205

(two) General requirements

1 raw material should be pre inspection

2 aluminum alloy parts should be surface anodic oxidation treatment, shaft steel surfaces there should be protective coatings; insulating laminated material workpiece surface application of insulating paint processing.

3 metal parts surface roughness should be = 6.3

Surface components should be regular, smooth. Insulation parts surface should be smooth, no bubbles, wrinkle or crack, no obvious abrasion and overheating signs, color should be color (from shallow yellow to brown)

Insulation ladder standards: GB 17620-1998
