Abstract
The invention relates to a T-shaped cable with a fault prompt and a working method for the T-shaped cable. A whole electrothermal film is waterproof, is normal in working performance and free of an electric leakage phenomenon through a high-voltage test of above 3750v in water for 48 hours, so that the T-shaped cable can be used in a humid state environment, but a user needs to pay attention to insulated waterproof treatment on a connection part and a cutting part. The T-shaped cable provides a power supply to the electrothermal film, forms a loop for a whole circuit, is a component matched with the electrothermal film, but easily causes the weak spots of insulativity and connection reliability frequently, is inconvenient to detect after a fault appears, and cannot ensure the operation safety of an electrothermal film heating system. The T-shaped cable comprises a T-shaped three-way insulating sheath (1), wherein the T-shaped three-way insulating sheath (1) coats a group of cable cores (2); a signal generator (3) is arranged on the T-shaped three-way insulating sheath (1); and the group of cable cores comprise two sensing cable cores (9), two signal cable cores (11) and a main cable core (8). The T-shaped cable is applied as the T-shaped cable with the fault prompt.
