Provided in the present invention is a 220 KV transformer movable sleeve for easy maintenance which includes a sleeve assembly and a connecting component. The sleeve assembly includes a sleeve and an end cap, and the access port is provided on the sleeve, the access port is matched with the end cap, and the connecting component includes a rotating part, a moving part and a driving part. The access port is arranged on the sleeve assembly, and the inspection can only be carried out by opening the access port during inspection, without dismantling the entire movable sleeve, and greatly improving the work efficiency. The rubber strip is combined with the metal sleeve. The method reduces the influence of magnetic flux leakage on the metal movable sleeve and prevents it from generating eddy current heating. Through the driving part, the end cap can be automatically opened, saving time and effort.

220KV transformer movable sleeve for easy maintenance

The present invention discloses a 220 KV transformer sleeve. The sleeve includes a sleeve assembly and a connecting assembly. The sleeve assembly includes a sleeve brace, an adjustable part coupled with the sleeve brace. The connecting assembly includes a rotating part and a mobile part. The sleeve is secured on the transformer core body through screws, and the adjustable part can be opened through the connecting assembly. When maintenance is required, there is no need to dismantle the entire sleeve. The work efficiency is greatly improved. This minimizes inductance leakage and prevents eddy currents from occurring.

220KV transformer sleeve

Disclosed is a personal care composition comprising cooling active and copolymer comprising acrylamidopropyltrimonium chloride, wherein the weight ratio of the amount of the cooling active to the amount of the copolymer is in the range from 1:5 to 100:1. The copolymer improves deposition of the cooling active during topical application of the product to skin.
