The insulated centipede ladder is easy to transport, assemble, and relocate. It can be used as an effective supplement to insulation carrying tools in rural distribution overhead line pole devices with complex structures and many pole attachments, which are not conducive to carrying out insulated pole operations with foot buckles and climbing boards.
1.Components of Insulated Centipede Ladder
1.1The basic section length of an insulated centipede ladder is generally 3-6m, with a pull ring at the upper end of each section. The extension section can be 2-3m.
1.2 The pull wire should be insulated rope, and the insulated rope should be made of materials with low ductility.
1.3The anchor pile should be an iron anchor pile, and the length of the anchor pile should generally not be less than 1.2m.
2.Inspection before assembly of insulated centipede ladder
2.1Before on-site assembly, surface inspection should be carried out on all components of the insulated centipede ladder, including the base, foot nails, rope fixing rings, and connection parts, to prevent defects such as cracking, rust, and bubbles from affecting mechanical strength.
2.2Surface inspection should be carried out on insulation ropes to prevent excessive wear and defects such as broken strands from affecting their mechanical strength.
2.3The anchor pile should be free from deformation and severe deformation.
2.4Use a 2500V insulation resistance meter to test the insulation resistance value of the upper section of the insulation centipede ladder and the insulation rope (temporary pull wire). The insulation resistance value should not be less than 700M Ω.
