The invention relates to a hard insulating shield cover specialized for 35kV live operation. The hard insulating shield cover comprises two shield units which are symmetrical in shape. The two shield units are oppositely arranged. Each shield unit is formed by two epoxy resin bodies and one nylon framework. The upper ends of the two epoxy resin bodies are connected by the nylon framework. The front ends, the rear ends and the lower ends of the two epoxy resin bodies have an open structure. An installing area used for installation of an iron tower frame in a penetrating way is formed between the two epoxy resin bodies and the nylon framework. A handle is installed on the nylon framework. An open groove is manufactured at the front end of the nylon framework. The invention provides the hard insulating shield cover specialized for 35kV live operation through design, and the hard insulating shield cover is convenient for operation of live operation personnel and is safe and reliable. After insulating shielding is performed on a live part by live operation personnel, a closer iron tower is shielded by using the hard insulating shield cover so that reliable insulating protection is provided to the live operation personnel in operation.
