The utility model provides an insulating coat which comprises sleeves, wherein each of the sleeves is provided with an insulating ring to be connected with insulating gloves. According to the insulating coat, through arranging the insulating rings on the sleeves, the insulating gloves are connected onto the insulating rings by an operator wearing the insulating coat and insulating gloves, since the hands of the operator wearing the insulating gloves are clumsy, and the operator is difficult to unfasten the insulating gloves connected to the insulating rings independently without the help of others, thereby preventing the operator from taking off the insulating gloves at will during the operation process, preventing the occurrence of safety accidents, and enhancing security.
