Insulated bucket vans ended up created in an energy to assist safeguard workers from electrocution. This applies to linemen who might be doing the job on utility strains such as phone poles or transformers, and so on. These jobs have the included threat of not only staying situated in superior destinations, but functioning around particularly superior voltage strains. This is why there was a need to have to create something that could also defend these personnel and lessen the risk of electrical shock.
There are 3 main features of an insulated bucket truck that can present defense from electric shock. These are the most critical parts to maintain and hold within just the criteria as described by ANSI:

It truly is a fantastic plan to normally hold these elements in brain when functioning near electric power. In addition, you ought to contemplate the humidity of your present environment as perfectly as atmospheric electrical energy this sort of as lightning. You must under no circumstances be doing the job in a bucket truck, near energy strains or not, if there is a lightning storm getting spot.
