Description

Technical Field

[0001] This utility model belongs to the field of overhead contact line cantilever insulator sleeves, specifically a cantilever insulator sleeve with bird protection function. Background Technology

[0002] The main purpose of cantilever insulators in electrified railways is to provide mechanical connection and electrical insulation between the contact wire and the support post, effectively supporting and fixing the contact wire to ensure its stable operation. It prevents direct contact between the wire and other metal components, thus guaranteeing the safety and smooth operation of railway transportation. The cantilever arm of the electrified railway cantilever insulator needs to be fitted with an insulating sleeve to protect the connection point from oxidation, corrosion, and damage caused by bare wires crossing above complex residential areas or demolished buildings, passing through tunnels, culverts, or bridges, as well as by wind, sand, dust, humid air, and acid rain. This effectively slows down outdoor corrosion of the bare metal wires. It also provides a certain degree of protection. While these devices prevent electric shock accidents, in actual use, they are mostly installed in relatively remote areas where birds frequently build nests on the covers. This makes the covers easily pecked and damaged, affecting their normal use. Furthermore, nests on the covers increase the probability of birds defecating on the surface, thus reducing the covers' lifespan. Therefore, to prevent birds from building nests on the covers and reduce the probability of birds landing on them, it is now necessary to add an ABS bird shield to the covers. However, since the two are installed separately, the covers must be installed first, making the installation process cumbersome and inefficient. Utility Model Content
