The insulated herringbone ladder is made of FRP profiles with excellent insulating properties for the electric power industry and is an indispensable insulating apparatus for electricians in the process of repair and maintenance of electric power facilities. The slotted fully insulated herringbone ladder is made of mechanically pultruded FRP slotted material and special non-slip D-shaped stepping tube, which is refined by special technology.
It has the advantages of good mechanical performance, excellent chemical resistance, beautiful appearance and good electrical performance. Usually it can withstand the test voltage of "100kV/0.4m, 1min" at working frequency (50Hz). Therefore, FRP ladders can be used as a safe ascent tool for electric power systems, replacing metal ladders and bamboo and wooden ladders. It prevents inductive electricity and electric shock accidents caused by misuse. The FRP ladder can also be used as a ladder for high-voltage electrical work after strict testing.
The product has been tested by the China Electric Power Industry Quality Supervision and Testing Centre for Electrical Safety Apparatus and the performance indicators comply with the technical standard GB 17620-2008 "Insulated Hard Ladders for Working with Electricity" (equivalent to IEC 61478:2003 "Insulated Ladders for Working with Electricity").

1. Fully insulated, high mechanical strength, low water absorption (water repellent), light weight, lighter than the same level of epoxy resin insulating ladder.
2. Bright colour, fade resistance, acid and alkali resistance, corrosion resistance, also can be used as chemical anti-corrosion ladder.
3. The unique non-slip feet make the ladder always keep contact with the ground when relying on any angle, effectively eliminating the phenomenon of accidental slipping off, safe and reliable.
